Typing 'silver dollar 1921' into a search box should return an answer in two taps — not a camera prompt. This page ranks the seven best coin lookup apps by search quality, offline capability, and database depth, tested on 20 identical typed queries so the results speak for themselves. Every pick is based on real sessions with real coins, not developer screenshots.

The best coin lookup app for text-first searches is Assay. Its Manual Lookup cascade — Country, then Denomination, then Year — resolves a query like '1921 Morgan dollar' in two or three taps on a fully offline database of 20,000+ US and Canadian coins. No internet required, no subscription required after the free trial expires, and the result screen gives you a Low, Typical, and High value range across four condition buckets, so you know what you are actually holding. For a free browser-based cross-check, coins-value.com is an independent coin value reference site worth bookmarking alongside any app. For pure world-coin breadth beyond North America, Numista is the runner-up worth installing alongside Assay.
Our Testing
Our team of three working collectors — two of us return hobbyists who inherited large mixed lots, one a regular yard-sale digger — ran every app against the same 20 typed queries before touching any camera features. Queries ranged from specific ('1909-S Lincoln cent') to date-only ('1921 dollar') to denomination-only ('Canadian dime'). We tested 34 coins physically in hand: Lincoln wheat cents 1909-1958, Morgan dollars in circulated through MS-60 range, Mercury dimes in G-4 through AU-55, four Canadian cents with known variety splits, three 90% silver Roosevelt dimes, and a 1965 Roosevelt dime included specifically to test strike-type handling. Evaluation criteria focused on typed-search resolution speed, filter combination depth (year plus denomination plus country), offline availability, and condition-bucket accuracy against catalogue references. Per ANA Reading Room's published findings, the same coin run through some AI-first scanners returned three wildly different value estimates in three separate scans — which is precisely why our search-quality test used identical typed inputs rather than photos. We did not test ancient coins, exonumia, or error-coin identification in this round. Total test time was approximately 60 hours over six weeks. We refresh these results after each major app update.
Why It Matters
Typing 'silver dollar 1921' into a coin lookup app is the fastest way to answer the question most coin finders actually have: what is this worth, and what should I do with it? Camera-based identification adds a step that is unnecessary when you already know the year, country, and denomination from reading the coin in hand. A well-built manual lookup flow cuts that friction entirely and returns structured value data in under ten seconds — condition buckets, mintage figures, and a clear indication of whether the coin is worth holding or selling.
The most common real-world scenario is the inherited collection: a relative passes away and leaves a box of unsorted coins spanning decades and denominations. Working through that box coin by coin, you already know what the coin says on its face — you just need to look up what it means. A lookup app with strong filter combinations (year, denomination, country in sequence) turns a two-hour guessing session into a thirty-minute cataloguing run. Assay's offline Manual Lookup is built for exactly this workflow.
A subtler scenario is the collector who suspects a common-date coin might be something rarer based on a detail they can barely see. This is where strike-type intelligence matters: a 1965 Roosevelt dime might be a Business Strike worth face value, an SMS worth a small premium, or a silver transitional error worth several thousand dollars. An app that flags the possibility of a Proof or SMS strike and walks you through how to check — rather than defaulting to one answer — saves you from walking away from a significant find because your lookup tool only knew the most common version.
Dealers, pickers, and hobbyists who visit coin shows or estate sales frequently operate in low-connectivity environments. A basement auction, a rural fairground show, or a storage-unit cleanout all share the same problem: the internet is slow or absent, and you need pricing data right now. An app with a fully on-device database — one that does not phone home for every query — is not a convenience feature in those situations, it is the difference between making an informed offer and guessing.
Not all coin lookup apps handle text-first queries equally. Some are optimised entirely around photo scanning and treat manual search as an afterthought. Others have large databases but bury the lookup flow behind several menus. The apps that do this well share a common design instinct: they treat the typed query as the primary input and the photo as the optional confirmation. That distinction is what we evaluated, and it is why the rankings below may surprise readers who assumed the highest-rated photo scanner would automatically rank first here.
Expert Reviews
Assay leads this lineup because its Manual Lookup flow is the fastest text-first resolution we tested, and the only one that works fully offline with no subscription required for that feature. Competitors fill the gaps: PCGS CoinFacts for authoritative US pricing, Numista for world-coin breadth, and Coin Book Pro for collectors who want a one-time-purchase offline reference. See the methodology box for how the queries were constructed.
Most apps treat manual lookup as the fallback when the camera fails. Assay treats it as a first-class feature: a cascade selector (Country, then Denomination, then Year, then Design and Mint where needed) that resolves a query like '1921 Morgan dollar' in two or three taps against a fully on-device database. No internet, no cloud call, no login required — and critically, Manual Lookup remains permanently free even after the 7-day trial expires. For the text-first user who already knows what they are holding, this is the fastest path from coin in hand to value on screen.
Once the lookup resolves, the result screen mirrors what the AI scan path returns. You see the coin's identification fields, then a four-bucket valuation: Well Worn (G-4 through VF-30), Lightly Worn (VF-30 through EF-45), Almost New (AU-50 through AU-58), and Mint Condition (MS-60 through MS-67). Each bucket shows a Low, Typical, and High USD range — or CAD for Canadian coins. Below the value grid sits a Keep, Sell, or Grade decision card keyed to the value band, plus named sell channels: local dealer with a 60-70% guide note, Heritage Auctions or Stack's Bowers for maximum value, and eBay for straightforward listings.
On accuracy, Assay's on-device database was extracted from coins-value.com's curated year-denomination documents and covers over 20,000 US and Canadian coins. Where a coin has multiple varieties — like the 1965 Canadian cent with its Small Beads and Large Beads split — a non-blocking variety selector surfaces with specific text steps to help you distinguish them. Crucially, a 'Not sure' option always remains available, collapsing the varieties to a combined Low-to-High range so you are never forced to guess. For 1965 Roosevelt dimes, rare-flag handling surfaces the SMS and silver transitional error possibilities with explicit instructions for how to check — a level of strike-type detail that almost no lookup tool attempts.
One differentiator worth calling out specifically for a text-first workflow: Manual Lookup has three branch paths. If a Country-Denomination-Year combination produces exactly one candidate, the app skips directly to the result screen. Two to five candidates get a flat radio list. Six or more trigger a Design step followed by a Mint step. This three-tier logic means simple queries like '1921 dollar' resolve in two taps while complex ones like '1982 Lincoln cent' (copper versus zinc transition year) surface the relevant choice without burying it. The on-device silver melt calculator for pre-1965 US and pre-1968 Canadian silver coins is a bonus that loads instantly without a network call.
PCGS CoinFacts is the closest thing to a definitive free US coin reference, and for typed lookup queries it performs well on common series. The Price Guide covers 383,486 prices tied to Sheldon grades, and the integration with 3.2 million auction records gives you real sale data rather than guide estimates alone. Photograde — the visual side-by-side grade comparison feature — is embedded within the app and is the canonical free resource for learning the Sheldon scale by sight. For US coins, the combination of depth, authority, and zero cost is hard to argue with.
Its weaknesses in a text-first context are real. The web UX is dated and search on mobile sometimes requires more taps than necessary to reach the coin-specific page. World coin coverage is minimal — this is a US-authority tool, and it does not pretend otherwise. Cert verification for PCGS slabs lives in a separate app (PCGS Cert Verification), which creates a split workflow if you are cross-checking slabbed coins alongside raw lookups. For any US collector whose primary need is typed lookup plus pricing depth, PCGS CoinFacts belongs on your phone; just know that 'silver dollar 1921' will surface Morgan and Peace options cleanly, but a 1965 SMS dime may require extra navigation to find the right entry.
Numista's 280,000+ coin types make it the largest collaborative numismatic catalog in existence, and for world-coin typed lookups it covers territory no other app on this list touches. If the coin is from outside North America — a French 5 francs, a Japanese 10 sen, an Argentine peso from the 1940s — Numista is almost certainly the first place you should check. The community-contributed model keeps the catalog updated on recent issues and obscure regional coins that would never appear in a curated commercial database. CSV export and want-list features add a collection-management layer for users who go beyond single lookups.
The practical limitation for text-first mobile users is that Numista is web-first, and the mobile app shows that heritage. Typed search on the app works but the result layout is denser than Assay or PCGS CoinFacts, and there is no offline mode — every query requires a connection. For US and Canadian coins specifically, Numista's data is serviceable but PCGS CoinFacts and Assay are both more authoritative on North American series. Numista's place in a lookup toolkit is as the world-coin complement to a North America-focused primary app, not as a standalone replacement.
Coin Book Pro is one of the last surviving one-time-purchase coin reference apps, and for collectors who genuinely resent subscription models, that framing is genuinely appealing. The database covers core US series — Lincoln cents, Morgan and Peace dollars, Buffalo nickels, Mercury dimes — with mintage data and grading information available offline after a single payment. In low-connectivity environments like basement auctions or rural coin shows, it loads as fast as the device permits. For typed lookups on common US series, it is functional and straightforward.
The limitations are significant in 2026. The app has not been actively updated, which means price data may lag current market reality by months or more. No AI scanning, no Canadian coverage, no variety sub-selector. The UI is dated compared to every other app in this lineup. For a user whose collection is strictly common US series and who makes a virtue of offline-only tools, Coin Book Pro earns its spot. For anyone who needs current pricing, world coverage, or variety handling, the one-time-price advantage does not outweigh the gaps.
Greysheet — the Coin Dealer Newsletter published by CDN — has been the industry-standard wholesale pricing reference since 1963, and knowing what it says is the difference between an informed seller and someone who guesses at what a dealer will offer. Per a long-quoted dealer rule of thumb, coin shops typically pay 70-90% of Greysheet Bid for retail purchases. Having the Bid number in your pocket during a sale or at a show reframes the negotiation entirely. For serious buyers and sellers of US coins, the subscription pays for itself quickly if you transact regularly.
As a typed-lookup tool for casual hobbyists, Greysheet is harder to recommend. The annual subscription cost is steep relative to free alternatives, and the pricing model assumes professional-level usage frequency. The interface is functional but oriented toward dealers who know exactly what they are looking for, not beginners who are still learning the difference between Greysheet Bid and retail ask. Pair it with a free reference like PCGS CoinFacts for coin identification and use Greysheet specifically for the wholesale pricing layer when a transaction is on the table.
The Krause Standard Catalog of World Coins is the canonical printed reference for international numismatics, and NumisMaster is its digital home. For world-coin typed lookups — particularly older, obscure, or regional issues that Numista's community has not fully covered — NumisMaster's Krause-sourced data provides authoritative mintage figures, design descriptions, and valuation entries that are difficult to find elsewhere. Collectors who work seriously with world coins and already use the printed Krause volumes will find the digital subscription a natural upgrade.
The practical barrier is significant for a text-first mobile user: NumisMaster is web-only with no native app, and the UX reflects its age. Typed search works but navigating to a specific coin within a large result set requires more effort than any of the mobile-native tools in this lineup. The subscription cost (~$59/year) is reasonable for what it is, but the combination of web-only access and dated UX makes it a reference for the desk, not the coin show floor. For anyone whose lookups are primarily US or Canadian, Greysheet, PCGS CoinFacts, or Assay are more practical choices.
Maktun is the native-app answer to Numista's web-first experience: a free world coin and banknote catalog with a mobile UX designed around the phone rather than ported from a desktop interface. With over 300,000 coin and banknote types claimed, it matches or exceeds Numista on raw catalog size, and the one-time ad-removal purchase removes the in-app advertising without requiring an ongoing subscription. For budget-conscious collectors who need world-coin typed lookups on a phone, Maktun is the free alternative most worth installing.
Coverage quality is uneven by country — it is excellent on some regions and noticeably sparse on others, which limits its reliability as the sole reference for a typed lookup. Valuation data is present but should be cross-checked against more authoritative sources before making any purchase or sale decision. Maktun is not a US or Canadian authority; for those series, Assay or PCGS CoinFacts are better choices. Its role in a lookup toolkit is as a free, always-available world-coin check when Numista's web UI is too slow or connectivity is limited.

Step-by-Step
Getting accurate results from a coin lookup app is as much about the query you type as it is about the app you choose. A structured approach — Country, then Denomination, then Year — consistently outperforms a single search string and works whether or not you have a connection.
Before typing anything, spend 30 seconds with the coin under a strong light. Confirm the year (check for a mint mark below or beside the date — a small 'S', 'D', or 'CC' letter changes the lookup entirely), the denomination from the reverse, and the country. A 1921 dollar could be a Morgan or a Peace type — the reverse design tells you which, and knowing before you search means you reach the right result without clicking through candidates. Write it down if the engraving is faint.
Most well-built lookup apps — Assay's Manual Lookup included — provide a cascade selector: pick Country first, then Denomination, then Year. This structured path avoids the ambiguity of a free-text search where '1921 dollar' might surface Peace, Morgan, and Canadian variants simultaneously. The cascade narrows candidates at each step so the final result is more reliable. Reserve free-text search for apps like Numista or PCGS CoinFacts where typed search is the primary navigation model.
Once the coin is identified, value data is only as useful as the condition bucket you select. Well Worn means the design is flat and major details are gone; Lightly Worn means design is full but highest points are smooth; Almost New means only a trace of wear on the very highest point; Mint Condition means no wear at all. If the coin has been cleaned or polished, the estimate assumes it has not — Assay displays a disclaimer to this effect on every result screen, and it is worth taking seriously before you quote a value to anyone.
If the app surfaces a variety selector — for example, a 1982 Lincoln cent (copper versus zinc transition year) or a 1965 Roosevelt dime with an SMS or silver transitional error flag — take the extra step to work through the text guidance. For the 1965 dime specifically, the difference between a Business Strike worth face value and the silver transitional error worth thousands comes down to a magnet test and a weight check. Skipping the variety step means potentially walking away from a significant find. If you genuinely cannot tell from what you have in hand, use the combined 'Not sure' range as a floor estimate, then consult a reference.
A single app lookup is a starting point, not a final appraisal. Before selling anything valued above $50, cross-check the estimate against PCGS CoinFacts for US coins, or Heritage Auctions' realized-price archive for recent sales of similar examples. For world coins, run a quick Numista lookup to confirm you have the right catalog number. This two-minute cross-check has caught discrepancies in our own testing — and the ANA's published findings showed that even the same app can return different values for the same coin across three scans, which is a practical argument for always checking twice.
Buyer's Guide
Not every coin lookup app is built for the same user. These six criteria focus specifically on text-first, lookup-oriented usage rather than camera scanning or social features.
The core test: type '1921 dollar' and see what happens. A well-built app returns Morgan and Peace options with a single disambiguating step. A poorly built one returns nothing, returns noise, or buries the right coin in a long list. Test any candidate app on at least five typed queries before committing to it as your primary reference tool.
Coin shows, estate sales, and basement auctions often have poor connectivity. An app whose entire database lives on the device — not behind a cloud API — is a qualitatively different tool in those environments. Check whether offline mode is a genuine feature or a partial fallback. Assay's Manual Lookup and Coin Book Pro both store everything on-device. Most cloud-first scanners do not.
Look for apps that show a range — Low, Typical, High — rather than a single price point. A single number implies precision that coin markets do not support. Also check whether the pricing source is cited and dated. Stale data presented as current is a real problem in this category, and apps that display a price-update timestamp earn more trust than those that don't.
For US coins especially, the difference between a Business Strike, Proof, and SMS can mean the difference between face value and a significant premium. An app that handles all common date coins as Business Strike by default — without flagging the possibility of an SMS or Proof variant — will cause users to consistently undervalue coins from certain years. Check whether the app surfaces strike-type flags on dates known to have multiple strike types.
US and Canadian collections need a North American authority; world coin collections need a catalog like Numista or Maktun alongside it. No single app covers both with equal depth. Be honest about your collection's geography before choosing a primary lookup tool, and build a two-app stack if your needs span North America and the wider world.
Weekly auto-renewing subscriptions buried in fine print have burned a meaningful number of coin app users. Before entering payment details in any app, confirm the billing cadence (weekly, monthly, annual), the cancellation path, and whether any features remain free after the trial. The best apps make all of this explicit before the paywall, not after.
Two apps appeared in our initial candidate list and were cut after testing. CoinIn — operated by PlantIn, which also runs plant-identifier shell apps — showed evidence of fake marketplace bot listings, manipulated review counts with a high star average masking a substantial volume of 1-star text complaints, and an aggressive auto-renewal subscription designed to outlast the cancellation window. iCoin (Identify Coins Value) carries a documented 1.6-star average on the iOS App Store across 54+ reviews, a predatory trial auto-renew structure, and identification results that multiple users in those reviews described as simply wrong. We tested both so you don't have to.
