Mint and issuing power
MintIdentifies the place of manufacture or issue of a numismatic object.: | Cos | Ancient regionAncient region.: | Caria (islands) | Modern countryModern country: Greece | AuthorityIdentifies the issuing power. The authority can be "pretended" when the name or the portrait of X is on the coin but he/she was not the issuing power. It can also be "uncertain" when there is no mention of X on the coin but he/she was the issuing power according to the historical sources: |
