About
Coinaikon is the ultimate digital companion for coin collectors and numismatists. Using advanced computer vision AI, it can identify thousands of US coins—from Lincoln pennies to Morgan Silver Dollars—simply by snapping a photo. Users get instant professional-grade condition assessments and real-time market valuations without waiting days for a traditional appraisal. The platform supports both photo-based and text-based searches (by coin name, year, and mint mark), giving collectors multiple ways to look up their pieces. A standout feature is the hybrid intelligence model: the AI provides grading and valuation estimates, but users can override these with their own assessments based on local market knowledge or personal expertise. Coinaikon includes robust collection management tools that let users organize coins by sets, track portfolio value over time, and access comprehensive historical data about each coin. The experience is fully cross-platform—scan coins on iPhone or Android and manage your collection on the web, with everything syncing seamlessly. The app is free to download and offers a free trial, with a subscription unlocking full features. It is built by Lhotse Vision, LLC and is ideal for casual hobbyists, serious numismatists, and professional coin dealers who want fast, accurate, and portable grading and valuation.
