About This Tool
Ancient coin identification is one of the most challenging and rewarding areas of numismatics. Our AI has been trained on thousands of ancient coin types from every major civilisation. For Greek coins, it identifies the issuing city-state, the deity or hero depicted, and the period. For Roman coins, it identifies the emperor, the reverse type, and mint marks. For Byzantine coins, it covers the complex succession of emperors from Constantine through the fall of Constantinople in 1453.
📸 Tips for Best Results
- ✓Ancient coins are often poorly preserved — submit the best-lit photo you can
- ✓Try raking light (light from the side at a low angle) to reveal relief detail on worn coins
- ✓Include a scale reference — ancient coin sizes vary enormously
- ✓Note whether the coin is gold (electrum/aureus/solidus), silver (denarius/drachm/tetradrachm), or bronze (sestertius/as/follis)
- ✓Photograph any legible lettering clearly — emperor names and mint marks are key identifiers

Frequently Asked Questions
Can it identify very worn ancient coins?
Yes, within limits. For heavily worn coins, the AI may provide a type-level identification (e.g., 'Roman Imperial bronze, 3rd–4th century') rather than a specific emperor and reverse type.
Are ancient coins legal to buy and sell?
Laws vary by country. In general, ancient coins with documented provenance pre-dating cultural property laws can be legally traded. Always verify the legal status in your jurisdiction.
