Scan a coin

AI-powered coin recognition in seconds

How scanning works

1. Take or upload a photo — Click the upload zone and select a photo of your coin. You can also use the camera directly on mobile devices.
2. AI analysis — The AI analyzes your image and identifies the coin. This usually takes less than 5 seconds.
3. Review results — You will see: country, name, mint year, material, weight, diameter, condition grade, and estimated market value (range).
4. Add to collection — Everything correct? Click "Add to collection". You can also edit the data beforehand.

Tips for best recognition

Duplicate detection

When you scan a coin that already exists in your collection, CoinScan shows a duplicate alert. This prevents accidental double entries. You can still add the coin if you actually own it multiple times.
