What Is the 1992 Close AM Error?
This tiny design mistake makes all the difference:
Reverse Design Anomaly
- The “A” and “M” in AMERICA are touching or nearly touching
- Regular 1992 pennies have a wide gap between the letters
- The reverse was originally intended only for proof coins, but it was mistakenly used on regular pennies
Obverse Side
- Standard 1992 Lincoln design
- Found with no mintmark (Philadelphia) and with “D” mintmark (Denver)
- The 1992-D version is much rarer and far more valuable

5-Step Authentication Checklist
Check AM Spacing → The “A” and “M” nearly touch
Verify the Mintmark → Must be 1992 or 1992-D, no damage or doubling
Reverse Diagnostics → FG initials placement confirms proof reverse
Grade & Color → Red (RD) Mint State coins bring top prices
Certification → Must be graded by PCGS or NGC with FS-901 label
