Welcome to the forum.  Sorry to say it is only damage.  The only mint marks in 1982 were D and S, definitely not one of those.

Welcome to the Forum

Not a mint mark and there is no exact location of a D mint mark. It can be anywhere below the date and to the right of Abe's jacket. Also there are no "A" mint marks.

That looks like  a plating blister or possibly some other damage. Photo a little out of focus to say for sure.

It could be a "D" mintmark that has been partially scraped off.
