The 1992-D Close AM penny is one of the most famous modern varieties in the Lincoln Cent series.
The United States Mint struck these pennies in Denver in 1992 using a copper-plated zinc planchet.
Most Lincoln cents from that year used the standard Wide AM design on the reverse.
A few working dies intended for proof coins ended up in the regular production line at the Denver Mint.
These misplaced dies created coins with closely spaced letters on the back.
Collectors watch for this red-colored coin because it represents a rare production mix-up from the early 1990s.
It holds the number 15 spot on our list of the 200 most valuable pennies.
A standout example of this variety crossed the auction block for $14,100.
Heritage Auctions sold the piece in February 2014.
The coin received a certified grade of MS-65 with a Red color designation.
The MS-65 grade stands for Mint State 65.
This means the coin shows no wear from circulation and keeps strong original luster.
The Red designation means the copper coating retains almost all of its bright, original factory color without fading to brown.
Serious collectors pay top dollar for high-grade specimens that carry strict third-party authentication.
Record prices like this one belong to elite, certified pieces rather than typical pocket change.
The Denver version of the 1992 Close AM variety is exceptionally hard to find.
The Philadelphia Mint produced a small number of Close AM pennies that year, but the Denver issue is even rarer.
Mint workers accidentally used a proof reverse die meant for the San Francisco Mint on standard Denver planchets.
The proof design placed the letters A and M in AMERICA right next to each other.
Billions of normal pennies entered circulation from Denver that year, but almost none of them used the proof die.
Because so few slipped out of the mint, survival numbers remain extremely low.
Lincoln Cent enthusiasts actively search for this variety to complete their modern collections.
The mix of extreme scarcity and strong collector demand drives the high market value.
You can look for this variety using a standard pocket magnifier or a coin loupe.
Start by looking at the front of the coin below the 1992 date.
Confirm that you see the small D mint mark for the Denver Mint.
Turn the coin over and look closely at the word AMERICA on the reverse.
Focus entirely on the bottom corners of the letters A and M.
On the rare Close AM variety, the bases of the two letters nearly touch or fully touch.
On a normal 1992-D penny, you will see a wide, distinct space between the bottom of the A and the bottom of the M.
You can also use CoinKnow or Coin Value Checker on your phone to get a quick first opinion before visiting a dealer.
Always inspect the letters under bright lighting to avoid mistaking surface dirt or contact marks for joined letters.
A verified Close AM with the Denver mint mark is a major find for any coin hunter.
