Top 6 Free Coin Identifier and Value Apps for Android & iPhone
1. CoinKnow – Our Top Recommendation
Following a comprehensive evaluation across numerous applications, CoinKnow claims our highest recommendation as the premier free coin identifier and value app for Android & iPhone. Debuting in 2025, this application harnesses cutting-edge artificial intelligence, trained on millions of coin images, to deliver identification results that rival those of professional numismatists.
Precision defines the CoinKnow experience. Using the industry-standard Sheldon Scale for grading, this application achieves an impressive 2-point accuracy. Such remarkable precision is essential when evaluating coins, where minor grade differences can represent substantial value differences. Professional graders rarely achieve tighter margins.
The standout capability that distinguishes CoinKnow is automatic error coin detection. Manufacturing anomalies, including doubled dies and missing mint marks, can elevate ordinary pocket change into collectibles worth hundreds or even thousands of dollars. CoinKnow ranks among only two applications worldwide that offer automatic detection of these lucrative errors, a functionality that most competitors entirely lack.
Sophisticated collectors appreciate specialized features, including copper color classification that differentiates Red, Red-Brown, and Brown designations, and Proof finish recognition that identifies Cameo and Deep Cameo characteristics. Monthly database updates guarantee pricing reflects current market conditions. Daily free scans deliver substantial utility without pushy subscription tactics.
Perfect for: U.S. coin collectors demanding professional-grade accuracy with error detection capabilities.
Look elsewhere if: Your collection emphasizes international or ancient coinage.
2. Coinoscope – Worldwide Coverage Leader
When collections span multiple continents rather than just American currency, Coinoscope provides unparalleled international coverage. This free coin identifier and value app for Android & iPhone has accumulated 1.7 million downloads while maintaining an impressive 4.5-star rating, demonstrating consistent performance across diverse numismatic categories worldwide.
The extensive database powering Coinoscope encompasses over 300,000 coins and 120,000 banknotes representing virtually every nation. Whether examining ancient Roman denarii, medieval European pieces, or modern Asian commemoratives, this application identifies specimens that region-specific competitors cannot.
Unlike purely algorithmic solutions, Coinoscope uses visual comparison technology to present similar coins alongside your specimen. This methodology proves especially valuable when examining worn or damaged pieces where exact matching challenges even advanced artificial intelligence. Viewing visually comparable options helps users comprehend identification logic and evaluate close matches intelligently.
Offline capability deserves particular emphasis for this free coin identifier and value app for Android & iPhone. Basic identification functions without internet connectivity, proving indispensable at coin shows, estate sales, antique markets, or anywhere WiFi remains unreliable. Collection management tools efficiently organize discoveries, while marketplace integration enables trading directly on the platform.
Perfect for: International collectors or anyone requiring reliable offline identification functionality.
Look elsewhere if: Maximum grading precision for valuable U.S. specimens takes priority.
3. Maktun – Maximum Database Coverage
For absolute comprehensiveness, no free coin identifier and value app for Android & iPhone rivals Maktun's extraordinary database scope. The application grants access to over 300,000 coin varieties, 160,000 banknotes, and 15,000 tokens spanning virtually every nation and historical era. When obscure or unusual specimens require identification, Maktun frequently succeeds where competing applications fail entirely.
The visual recognition engine driving Maktun matches coins purely through appearance without demanding prior numismatic expertise from users. Simply photograph both sides of any specimen, and the system searches its massive database for corresponding matches. This methodology works exceptionally well for inherited collections containing unfamiliar pieces or travel souvenirs acquired without proper documentation.
Maktun accommodates both newcomers and experienced collectors with remarkable depth. The interface remains welcoming for beginners while providing sufficient detail to satisfy veteran numismatists researching obscure varieties. Cataloguing features organize diverse collections spanning multiple countries and centuries into coherent, searchable archives that grow alongside your collection.
Perfect for: Collectors with eclectic worldwide holdings or inherited collections of uncertain origin.
Look elsewhere if: Precise market valuation matters more than identification breadth.

CoinSnap embodies this philosophy, delivering a free coin identifier and value app for Android & iPhone that prioritizes effortless operation above everything else. Aim your camera, capture an image, receive identification results within seconds. No complex menus, no bewildering options, just immediate answers to your questions.
Despite remarkable simplicity, CoinSnap provides genuine capability. The database encompasses over 240,000 coin types ranging from ancient issues through modern currency with claimed 99% accuracy. The application distinguishes Mint State from Proof coins, delivers automatic grading estimates, and calculates market values based on detected condition.
Artificial intelligence powers error detection within CoinSnap, identifying minting anomalies that boost value beyond face amount. Collection management tools organize specimens by series, track cumulative worth, and monitor portfolio growth over time. Historical information accompanies identification results, adding educational context that enriches the overall collecting experience.

The gentle learning curve welcomes beginners without overwhelming them with professional terminology or complicated features. As expertise develops, users naturally transition to sophisticated applications while retaining CoinSnap for rapid lookups.
Perfect for: Beginners and casual enthusiasts prioritizing speed alongside simplicity.
Look elsewhere if: Maximum precision for rare or high-value specimens remains essential.

Perfect for: Investment-minded collectors requiring market analysis alongside portfolio tracking.
Look elsewhere if: Simpler interfaces appeal more, or international coins dominate your collection.
6. PCGS CoinFacts – Authoritative Reference Standard
Professional Coin Grading Service developed PCGS CoinFacts as the definitive encyclopedia for U.S. numismatics. This free coin identifier and value app for Android & iPhone differs fundamentally from camera-based alternatives by functioning primarily as a research tool. Users must already know their coin's identity before accessing the application's extraordinary informational depth.
