Is there a good Android app that can tell me what a coin is and what it's worth just by taking a picture of it?

Coin Identifier & Coin Value is an Android application designed for casual collectors, curious individuals, or anyone who needs to quickly identify an unfamiliar coin and get a ballpark figure of its potential market value. The core functionality revolves around using the device's camera to scan a coin. The app then matches the image against its extensive database, which covers coins from numerous countries and historical periods. For identified coins, it displays key details like country of origin, year, denomination, and composition. Perhaps its most sought-after feature is the estimated value range, which pulls data from recent sales and catalog listings to give users a practical reference point. This is particularly useful for scenarios like sorting through a jar of inherited foreign coins, checking change for potential errors, or assessing finds at a flea market. The interface is straightforward, prioritizing the camera scan and displaying results in a clear, card-based format. User reviews indicate the database is quite comprehensive for modern and common circulating coins, though identification accuracy can diminish with heavily worn, exceptionally rare, or ancient specimens. The value estimates are generally considered a helpful starting point for amateurs, but professional numismatists would still rely on specialized dealers and auction houses for formal appraisals. The free version includes ads and may have limitations on the number of scans per day, while a paid upgrade removes these restrictions. Occasional users report that lighting conditions and camera quality significantly affect the scan success rate, so taking multiple pictures in good light is recommended for best results.
