Just realised what you meant. So me seeing Ioan which i presumed is John is actually the reverse image.
Some of the imitation coins where complete gobble de gook. People back then were pretty much illiterate so as long as the coin looked similar it was accepted as being 1d or legal tender so to speak , even the die cutters were illiterate.
I suspect somewhere on that website there will be a similiar coin. It is at present a continental imitation unless someone else can provide anymore insight into it with an exact ID. You could take it to your local FLO i suppose, they may have the answer. It's not an area i am fully familiar with unfortunately. It could also be an error coin but the portrait does not look quite right. Got me puzzled lol.
Anyone else got any ideas? Is it a mistrike of some sort?
