About Coin Identifier
Coin Identifier is the editorial website behind Coinara — widely regarded as one of the best coin identifier apps for iPhone. Coinara is an AI-powered iOS mobile app that identifies coins from a single photo and returns current market values. Whether you’re a serious collector, a casual hobbyist, or someone who just found an unfamiliar coin in a drawer, Coinara puts expert-level identification in your pocket.
The iOS App
Coinara is available exclusively on the iOS App Store for iPhone and is free to download. Snap a photo of any coin’s obverse and reverse, and the app’s AI matches it against a trained database of 50,000+ coin types — covering US, world, and ancient series. You’ll get the coin’s identification, key date and mint mark detail, historical context, and a current value estimate based on auction comparables from major houses (Heritage, Stack’s Bowers, PCGS price guide).

Important: AI Identification
Identifications and value estimates are produced by AI models. They are useful starting points, not professional appraisals. For high-value coins, always consult a certified grader (PCGS, NGC, ANACS) before buying, selling, or insuring.
