CoinSage: Coin Identifier

Ever wondered what that old coin is worth?

Point your camera at any coin, snap both sides, and CoinSage tells you what you're holding: name, country, year and an honest value estimate.

WHY COINSAGE IS DIFFERENT
Most coin apps promise certainty and inflated prices. CoinSage shows the real confidence score for every identification and realistic value ranges based on recent sales, clearly marked as estimates, not appraisals. If we get a coin wrong, you can correct it in two taps.

• Honest confidence scores and alternative matches, always visible
• Manual correction with catalog search when we miss

KNOW WHAT IT'S WORTH

PRIVACY FIRST
Coin photos are analyzed to identify your coin, then discarded. They are never used to train AI models unless you explicitly opt in.

All value information is an estimate based on recent sales data and does not represent a professional appraisal. For buying, selling or insurance decisions, consult a certified numismatist.
