The 1990s: A Quiet Revolution in Coin Minting
While not as historically romantic as coins from the 1800s, the 1990s were surprisingly rich in rare minting errors and experimental die varieties. The U.S. Mint was transitioning to new minting technologies and updating designs — and some slip-ups happened along the way. For collectors, those mistakes are goldmines.
These errors were often not caught until years later, when sharp-eyed collectors spotted inconsistencies and flagged them for grading. As a result, coins that were once worth a single cent are now worth thousands. Let’s explore the rarest of them all.
Coin #1: 1990 No-S Proof Lincoln Cent
What It Is
In 1990, proof pennies were minted at the San Francisco Mint. Proof coins normally carry an “S” mintmark. However, due to a die error, a small batch of these coins were released without the mintmark. This minting mistake turned them into one of the rarest Lincoln cents ever produced.
How Much It’s Worth
High-grade examples have sold for over $20,000. Lower-grade versions still command several thousand dollars.
How to Identify It
Look for a 1990 Lincoln cent with a mirrored, high-quality finish (proof), but without the “S” mintmark. Be cautious, as regular Philadelphia cents also lack a mintmark but are not proof coins.
Coin #2: 1992 Close AM Lincoln Cent (Philadelphia and Denver)
What It Is
A Close AM variety means the letters “A” and “M” in “AMERICA” on the reverse side of the coin are almost touching. This feature was supposed to appear only on proof coins, but a few circulation-strike coins received the proof reverse die by mistake.
How Much It’s Worth
Prices range from $500 to over $10,000 depending on condition and mint mark.
How to Identify It
Look at the reverse of the coin. If the “A” and “M” in “AMERICA” are touching or very close, you might be holding a rare Close AM cent.
Coin #3: 1999 Wide AM Lincoln Cent
What It Is
This is the opposite of the 1992 error. In 1999, Lincoln cents were supposed to feature a Close AM design. However, a proof-style Wide AM die was mistakenly used for some business strikes.
How Much It’s Worth
In uncirculated condition, these coins can bring in between $250 to over $1,000.
How to Identify It
Check the spacing between the “A” and “M” in “AMERICA.” If there’s a noticeable gap, you’ve got the Wide AM version — a collector’s favorite.
Coin #4: 1990 Washington Quarter Mint Errors
What It Is
While most 1990 quarters are standard, a number have been found with striking errors — including off-center strikes, wrong metal planchets, or doubled dies.
How Much It’s Worth
Prices can range from $50 to $500+ depending on the nature and severity of the error.
How to Identify It
Look for irregularities like a misaligned image, clipped planchet, or incorrect coloration. These visual clues are often signs of a valuable minting error.

Real-World Case Study

According to a 2023 report by the Professional Numismatists Guild, the U.S. rare coin market reached over $6 billion in annual sales. High-quality error coins and varieties are seeing increased demand as investors seek tangible assets amid market uncertainty.
