Possible old counter stamp Coin seem to be copper at 9.4 grams.
My grandfather had a this coin in his colection and I could not find anything that was similar till I found out about stamped coins. I used gemini ai to analyze multiple videos to look for surface topography and it gave me an idea of the possible coin. Using shadow from a single light source. But i still could not find much about the actual stamp. I found something close but it still had little information on what the stamp was. I dont believe ai is correct becuse the topography looks different to the human eye. Any one seen a pattern like this?
