1992 Proof Lincoln Cent

Quote:
Until 1992, both proof and business strike Lincoln cents were made using the same type of reverse die all with a Wide AM. In 1992 the mint created a new reverse with a Close AM for that seems to be intended for use starting with 1993 cents. All 1993 cents, proof and business strikes, have a Close AM reverse. Beginning in 1994, the mint began using the old Wide AM reverse on all proof strikes and the new Close AM reverse on all business strikes. In other words, instead of using the same reverse on both proof and business strikes, the mint began using different reverses on cents dated 1994 and beyond. If things went according to plan all proof cents dated 1994 and on would have the Wide AM design, and all business strikes would have the Close AM design. Naturally all 1959 - 1992 cents should have had Wide AM designs on both proof and business strikes. Well, mistakes must have been made because several variations have appeared. 1992 and 1992 D business strike cents have been found with Close AM reverses. 1998, 1999, and 2000 business strike cents have been found with Wide AM reverses. And, 1998 S and 1999 S proofs have been found with Close AM reverses.
