About Coin Collector

Coin Collector is a mobile-first app built for numismatists, hobbyists, and collectors of United States coins and paper currency. Whether you're just starting out or managing a large portfolio of bullion and rare currency, Coin Collector helps you catalog every item, research its background, and track its estimated value over time — all from your phone.

Our AI-powered identification tool lets you look up a coin or bill by description or photo, pulling details like year, denomination, metal composition, mint mark, and estimated market value based on recent sold listings. Premium subscribers can bulk-scan entire trays with the Collection Scanner, view portfolio growth charts, and store an unlimited number of items. Free users can manage up to 20 items with manual entry and base price information, so the app is useful at every level of collecting.

Coin Collector is built and maintained by an independent developer based in the United States. We're committed to keeping the app simple, private, and genuinely useful for collectors at every level — no clutter, no noise, just the tools you need to understand and grow your collection.
