Help with identification of unknown coin

[OliwierEB]

Hello, I've had this coin for a while but am unsure of what it actually is. Hopefully on eof you'll be able to help me identify this coin, it seems quite mysterious to me.

Thank you.

Pictures are too dark to be much use, but it looks like IOAN CASI and the date is 1661 in which case it is probably Johann Casimir of Thorn in Poland. I can't match anything, but there again I can't see much in the picture. Whether it is real or not I can't say. Size?

Sorry for the lighting, it has a diameter of 16mm.

Hello can anyone help to identify this coin, found in my garden. Many Thanks

Not a coin, but a counting token or Rechenpffenig. Made in Nuremberg, Germany and used on a counting board to work out accounts before Europe adopted the Arabic concept of zero as a number. Just google rechenpffenig and all will be clear.

These Nuremberg Jetton are actually quite common metal detecting finds in the U.K., but you were nonetheless lucky to spot it. It might improve with a gentle scrub with a soft brush in cold water.
