    Our model reads the design, legends, mint marks, and metal to identify exactly what you’re holding.

Questions

Frequently asked

How accurate is Coin Identifier?

Coin Identifier uses advanced AI to recognize coins from a photo and is remarkably good at naming country, denomination, era, and design. That said, it is an AI assistant — always confirm grade, authenticity, and value with a qualified dealer or certified grading service before buying, selling, or insuring.

Can it estimate what my coin is worth?

Yes. Each report includes an estimated value range plus the factors that drive it — condition, rarity, metal content, and collector demand. Treat it as a starting point for research, not a formal appraisal.

Do I photograph both sides of the coin?

For the best result, capture both the obverse (front) and reverse (back) in good light. Clear shots of the design, lettering, and any mint marks help the AI pin down the exact coin and variety.

Is it free to use?

Coin Identifier is free to download and start identifying coins right away, on both the App Store and Google Play.
