    I found a 1982 d penny that appears to have 2 mint marks in completely separated locations. One in the correct location and the other to the left of the date. Does this appear to be a minting error or is it caused from bubbling of the copper playing?

    That would be Plating bubble issue.

    Happens when air gets in the metal. Very common on zinc cents.
