Sounds like a "wrong stock" error, although I think the weight is a
bit high for it to have been struck on quarter stock.

I might add that the thickness looks slightly thinner on this 1980 vs.
other coins from that era. Maybe it was a thinner planchet that was
used?

Assuming that quarter stock instead of half dollar stock was inadvertently used
to make blanks, the details of the coin should be weak and indistinct.
Unless, of course, the dies were not properly adjusted.

I might add that the thickness looks slightly thinner on this 1980 vs.
other coins from that era. Maybe it was a thinner planchet that was
used?
Does it have all 3 clad layers? Possibly delaminated before being struck?
