During nearly every year of the 1990s, the U.S. Mint made minor
design changes to the Lincoln cent, likely aimed at improving die life.
One change is significant enough to have captured the fancy of
collectors: the relative spacing of the letters AM in AMERICA on the
All Lincoln cents produced from 1959 to 1991 had a comparatively
broad spacing between these two letters. In 1993, all Lincoln cents
show a change; the letters AM in the word AMERICA are close together,
The year 1992 marks a transition. All Proof 1992 coins are of the
normal Wide AM variety, as are nearly all the circulation-issue coins.
But a very small number of 1992 cents from both the Denver and
Philadelphia Mints are known to have the Close AM reverse. Fewer than
two-dozen Denver Mint examples are reported, and only a handful of
1992 Close AM cents from the Philadelphia Mint have been found. The
rare Philadelphia Mint variety carries a catalog value in excess of $10,000.
On circulation issues, the Close AM reverse remained in use until
the final year of the Lincoln Memorial design in 2008. For Proof
issues, the Close AM reverse was used in 1993, but in 1994 the Wide AM
returned for use on all Proof issues until the end of the series.
There are exceptions, creating interesting coins for collectors.
In 2001, die-variety expert John Wexler found a circulation-issue
2000 Lincoln cent with a Wide AM reverse, the version intended for
Proof coinage. Shortly thereafter, a 1998 Lincoln, Wide AM cent was
also found. Both were discovered in roll quantity, and, although not
common, they are available.
Sometime later, the 1999 Lincoln, Wide AM cent was found to fill in
the gap. Only about 500 examples have been certified and they are the
scarcest of the Wide AM circulation Lincoln cents of this era.
To add to the intrigue of these coins, Proof coins also exist with
the Close AM reverse for the 1998-S and 1999-S issues. In other words,
the circulation-strike-style reverse was used to make Proof coins. The
1999-S Close AM cent is more common than the 1998-S Close AM cent.
Examples graded Proof 69 Red Ultra Cameo trade for around $175 and
$300, respectively, a hefty premium over the standard issue that is
available for under $20.
Enthusiasts will seek to complete the set of all reverse types for
both Proof and Mint State issues. For the rare 1992 issues,
professional certification is recommended.
