Welcome to Numista. You said it yourself. Mangled and damaged in it's 44 year history of circulation  Meaning this is not an error at all and it  is post mint damaged. Exactly what is to be expected in a heavily circulated coin. This all happened long after it was minted. It is still worth exactly 10 cents. You must understand the definition of error or implied Mint error before proclaiming a coin to have one.
