is this a true mint error? the '1' in the date is missing, and that looks like a grease die error. what the heck happened to the 8 or 9 though? It is definetly an 8 or 9 because there in a nice S mintmark on the reverse of the coin. the reverse of the coin has no marks on it (i.e. completely normal), as does the rest of the obverse.

let me know what you think.

Looks like something was on the die when the coin was struck.

Actually it's a simple case of an altered coin with no value.
