Over Mintmarks (OMM's)
The above list represents the most commonly accepted over mintmarks
(OMM's). It may seem strange to you that the mint would change its mind after
punching a mintmark, especially if you think that the S mintmark is punched at
the San Fransisco Mint and the D mintmark is punched at the Denver mint.
The truth is that both the S and D mintmarks are punched at the Philadelphia
mint were all dies are prepared.
What about the 1980 D/S cent?
The 1980 D/S omm 1 was debunked in 2006. Die Variety News
had an article proving that what looked like an S was actually die gouges
in the field. The article was Vol. No 2. July/Aug 2006 written by Billy
Crawford.
