Alright guys
Sorry if some of you thought i just ignored the experts, which i didn't. just wanted more opinions.
I will trust you and accept the facts. I guess it could be a
fake from the 1800-1900s.
But it's probably no point in investigating deeper on this object.
The reason i really thought it was real is because i've found a belt buckle and some other
medieval things on the same place, and those things are real
Thanks for all the answers, i know where to write if i really find a ancient coin!
