They stopped hand punching MMs into dies back in the 80s so it's not possible to have a repunched MM. I don't see anything out of the ordinary with your MM. Just looks to be a circulated quarter.
There might be some mechanical doubling at the Mintmark, although it can't be seen in the small photo. If so, that type of doubling is not considered to be an error, and it has no premium as an error coin. worth face value only.......
