Hello Everyone, I got a question as to whether the coin I have in my possession is an original or not. The coin says "BURG.COTYR.1780.X" I checked it online and have found quite a bit of details about but don't know if my one is original. I have this coin for a long time but can't remember how I came about it. I hope someone can help or know someone or somewhere that might. I thank in advance for any help given. If anyone requires a picture please give me your email and I will send it as I cannot post it here.
