Without pictures hard to tell anything. Only thing might we might be able to help with is the "wide AM" for 1988 is that PCGS
lists is confusing. They actually mean that the 1988 has the reverse of the 1989 coin. Both 1988 and 1989 have AM separated, and the change is only really noticeable in in the "G" of the FG initials. Look at pictures of 1988 reverse and 1989 reverse in that area.
