dimples on 1988-S Lincoln - what are they?

CarlWohlforth

Old Abe looks like he has the hives or a major case of pimples. Does anybody know what this is or how it happened?

PMD, Rusted Die?

Interesting though.

It appears I won you giveaway contest Carl.
I hope it's not poor form of me to decline the prize.

CarlWohlforth

Gee, that is kind of you to decline the prize, I'm sure someone else will enjoy this extra Saint I have here

just kidding, there are no prizes or extra Saints here...


Thanks for the replies folks!

Carl, can you make the bubbles 'move' by touching them with a pin? Or puncture the surface? If not, it would be pre-plating contamination or surface irregularities. Cheers, RickO

RickO - This Lincoln resides in a proof set. I don't want to crack it out of the US Mint plastic holder. They look solid though.

This happened to a lot of the Zincolns, especially from the mid and late 80's business strike and proofs.

This variety had more than it's share of the problem.
