Proof vs Business Master Hub Discrepancy
From 1994 to 2008, the U.S. Mint maintained two distinct master hubs for the Lincoln Memorial reverse: the Business Strike Hub (Close AM) and the Proof Strike Hub (Wide AM):
In 1998, 1999, and 2000, Philadelphia mint technicians mistakenly paired proof-intended reverse dies with business strike obverse dies, releasing the coins into circulation.
Relative Scarcity & Mintage Survival
The 1999 Wide AM is by far the rarest of the trio, having been struck from only an estimated 1 to 2 reverse dies:
Additionally, designer Frank Gasparro's initials ('FG') on the Wide AM reverse sit significantly closer to the Memorial base and feature a distinctive serif on the letter 'G'.

Frequently Asked Questions
What is the 'Wide AM' Lincoln Cent error?
It is a rare transitional variety where business strike pennies (normally featuring 'A' and 'M' in AMERICA touching) were accidentally struck using a reverse die intended for proof coins (which features wide spacing between A and M).
Which years have the Wide AM variety?
The Wide AM error occurs on Philadelphia circulation pennies from three specific years: 1998, 1999, and 2000.
Why is the 1999 Wide AM worth more than 1998 or 2000?
The 1999 Wide AM is vastly scarcer than the other two years. An estimated 2,500 exist for 1999, compared to roughly 25,000 for 1998 and over 100,000 for 2000, making 1999 worth $400 to $1,500+.
Can I find a Wide AM penny in pocket change?
Yes! Millions of 1998, 1999, and 2000 pennies are currently in circulation. Anyone searching bank penny rolls can cherrypick these varieties with a simple 10x magnifying glass.
What secondary marker confirms a Wide AM?
Look at the designer's initials 'FG' to the right of the Memorial base. On a Wide AM, the initials sit very close to the building (Close FG) and the 'G' has a distinct horizontal serif.
Is there a 'Close AM' variety that is valuable?
Yes! The exact opposite variety exists for 1992: in 1992, the normal strike was Wide AM, but rare mules were struck with Close AM (Style of 1993), which are worth over $25,000!
Does the Denver Mint (D) have Wide AM errors?
No. The 1998, 1999, and 2000 Wide AM varieties only occurred on Philadelphia strikes (no mintmark).
