It's made of copper and about 27*26mm. It looks like a boat on one side and 4 lis on the other side. I cannot read the inscription. And here's an eye on the side of lis. Anyone knows about this hammered coin? Thanks for any information!
I find out at last. It is an anonymous Nuremberg 'ship-penny' jeton with fictitious legends, which was issued around 1490-1550.
