Is this a double die on the 8, 7 and on the D? 20230212_213145.jpg

In my opinion, it looks lower and step or shelf like. I believe it's what they call worthless doubling. Another thing to note is, prior to the mid 1990s, the working dies which made coins, were created first. It was after that the mint marks were added. So, if some sees doubling on the mint mark, it could be either worthless doubling or, a repunched mint mark.

Mechanical doubling, machine doubling, ejection doubling, strike doubling, are considered worthless doubling since it happens so often.
