1992 Penny Proof Reverse

Try this...http://www.lincolncentresource.com/wideams.html

I think some hubs got mixed up those years. 1998& 1999 proof had some close "AM's and 1998-2000 had some wide "AM"s. They were not proof dies used on business strike cents. Just the wrong punches used on the dies at that time.

No. Through 1992 the proofs used a Wide AM reverse In 1993 the proofs used a Close AM. From 1994 through 2008 the proofs used a Wide AM reverse.

In 1998, 99, and 2000 at least one reverse die hubbed with the Wide AM proof die hub was accidentally used to produce business strikes. Also in at least 1998 at least one rev die hubbed with the Close AM business strike hub was polished and used to strike proof Close AM cents. I am not sure if Close AM proofs were made in 99 or 2000.

In late 1992 when the mint was preparing dies for both 1992 and 1993, at least one rev die hubbed with the 1993 Close AM hub was used to strike 1992 cents at Philadelpha and one struck cents at Denver.

This gives us currenly known

1992 WAM common CAM very rare
1992-D WAM Common CAM very rare
1992-S all WAM
1993, D, and S all CAM
1994 - 1997 P,D all CAM there is a rumor of a 1996 WAM. After 1996 WAM's at Denver are not possible because they started making their own dies and they did not have access to the WAM proof hub.
1994 S - 1997 S all WAM
1998 WAM scarce CAM common
1998 S WAM common CAM very rare
1999 WAM rare CAM common
1999 S WAM common CAM ? does it exist?
