@Anoris. Welcome to Coin Talk. You will probably get more replies if you started a new thread. Also, post clear photos of the coin so we will be able to see what you're talking about. From what you did say, it sounds like you already know the coin was struck by a grease filled die, which does not add much value to the coin
