The US Mint produced two major varieties of the 1999 Lincoln Memorial Cent (Penny). The most common variety for the Philadelphia-minted 1999 is the close "AM" variety. In the word "AMERICA" on the reverse of the coin: The close "AM" meant that the letters "A" and "M" were very close and almost touching while the wide "AM" had the two letters separated much more. In Addition: The initials "FG" was closer to the Lincoln Memorial Building on the wide "AM" variety and it was further away on the close "AM" variety.
