The AI catches details other apps completely miss, like copper color variations (red, red-brown, brown) and proof finishes. What makes CoinKnow exceptional is its ability to automatically detect error coins, which could mean the difference between a $5 coin and a $500 treasure.
You’ll get monthly price updates without annoying ads cluttering your screen. If you’re testing wheat pennies from Grandma’s collection or verifying pocket change, CoinKnow nails the identification every time. For iPhone users serious about accuracy, this is your best choice.

The app claims 99% accuracy across 300,000+ U.S. coins, which you’ll confirm through use. The interface takes some getting used to, but once you learn it, you’ll have professional-level market data right on your iPhone.
4. Coinoscope
Got a box of international coins from your travels? Coinoscope becomes your lifesaver. When you find a 1943 Canadian penny in the mix, the app’s visual search shows you similar coins side-by-side, making identification easy even when the coin is worn.
With 300,000+ coins and 120,000+ banknotes from around the world, it handles foreign currency that U.S.-focused coin identifier apps simply can’t identify. You’ll appreciate the offline functionality—perfect when you’re at estate sales or coin shows without reliable internet.
The visual comparison approach works brilliantly for damaged or worn coins. With over 1.7 million downloads and a 4.5-star rating, you’re getting proven reliability. If you’ve got a drawer full of coins from different countries or inherited a mixed collection, you’ll find Coinoscope absolutely essential for your iPhone.
5. PCGS CoinFacts
When you need to verify the authenticity of a 1909-S VDB Lincoln cent, PCGS CoinFacts is your answer. This isn’t just an identifier—it’s the definitive encyclopedia created by the Professional Coin Grading Service.

If you love the stories behind coins, you’ll find Numiis magical. The database covers nearly 30,000 U.S. coins with rich historical context about each era, political situation, and cultural significance.
When you scan various buffalo nickels, you’ll discover fascinating details about the Native American chief who modeled for the design. The filtering options let you search by year, country, mint mark, and historical period. You’ll find it perfect for education or if you view coin collecting as a window into history. The downside? Only the trial period is free, but if you’re a history enthusiast, you’ll find the subscription absolutely worth it.
