I have having a problem on finding this one. The obverse is a galloping rider with a dog underneath. I can make out some of the inscription as SE?MUAIKON. The reverse is incuse squares, more or less The weight is 13.5 grams, presumably of silver. Any help much appreciated.
I'm not sure what it's supposed to be but it doesn't look ancient. Edited: it loosely copies a rare coin of Sermylia. CNG example: Sale: Triton VIII, Lot: 126. Estimate $15000.

Looks like a reproduction of a coin from Sermyle https://nomosag.com/default.aspx?pa...ionid=2&id=54&p=1&s=&ca=0&co=0&re=0&ci=0&ru=0
