Looks like the coin was already minted then some damage occurred. The damaged area looks like a completely different metal than the coin. I look forward to your 2 cents @paddyman98, have at me!
Oh god how could I have forgotten the pic? I'm so impressed at my own mistake I'm not even embarrassed. Well maybe a bit. Am I at least entertaining? Maybe slightly extremely annoying? Pardon me I'll show myself out. Or will I? Stay tuned for another blunder .
Don't worry. It happens. Look like some old soder attached to your coin. It maybe had a pin attached to it at one time. But that is definitely not a Die Break nor any kind of mint error.
