Here is a list of coins with close and wide AM varieties that one could find in circulation. 1992: Close AM 1992-D: Close AM 1996: Wide AM 1998: Wide AM 1999: Wide AM 2000: Wide AM
I am sure anything is possible. Prior to 1992, the Mint used the same reverse design for both proofs and circulation strike coins. In 1992, the Mint began using different reverse designs for proof and circulating coinage. This year marked the beginning of the Close and Wide AM varieties. Between 1992 and 2000 looks like the years these varieties can be found. The 1996 I listed was in the Redbook.
