Hi... Newbie here. A friend found this detecting in Greece. Near Thessalonica. ...But he also finds a lot of Roman. Instinct says Greek...it’s thick like Greek. Lambdas look Greek, but the letter C...isn’t a Greek letter. Any hints? Thanks a bunch! Lapiz
Yes. It's a Roman provincial coin of Domitian and his wife Domitia, minted in the part of the empire that was predominantly Greek. Quite a nice example, too.
You might like to point your friend to this list of countries with legal restrictions on metal detecting. It could safe them a lot of pain and trouble. I quote: "Greece. The owner of a metal detector must obtain a license which is issued by the Ministry of Culture. Metal detecting on beaches requires the mayor’s permission. It’s prohibited to search for archeological objects – jail term of 10 to 20 years" (emphasis mine).
The letter C is a Greek letter. It's called a lunate sigma and it was in widespread use during the Hellenistic and Roman eras.
