Found this in my change today. Thought it might have been post mint damage but all the lines seem to be facing the center of the coin. Definitely odd. Can anyone give me a definite answer? Thanks in advance!
If so, then using what? I'm sitting here trying to figure out what kind of tool or machinery could make lines that all face towards the center.
It's just a guess, but a file could have been used if the person took their time. Since you have the coin in hand, can you tell me if the marks are tapered toward the edge? This would prevent any damage to the devices in the middle of the coin. Chris
This is one of those times where knowledge of how coins are minted is proof that it couldn't have happened at the Mint, whether we ever know the cause of the current damage or not. The complete obverse rim proves the collar was present, meaning the reverse could not have been struck that way for any reason. All we have is speculation as to the cause of the damage, unless the person who caused it posts here. It's actually kind of interesting, though - has any of the base metal under the cladding been exposed? I would expect it to have been, had a file been employed.
Thanks for the replies. Now that you mention it, it does appear that the base metal is showing underneath. Guess it's a spender.
