The 1990 No-S Proof Lincoln Cent stands as a remarkable anomaly in modern numismatics. This coin, distinguished by the absence of the ‘S’ mint mark, has captivated collectors and investors alike.
With fewer than 200 known specimens, its combined market value approaches an astounding $99 million.
Origins of the 1990 No-S Proof Lincoln Cent
In 1990, the U.S. Mint‘s San Francisco facility, responsible for producing proof coinage, inadvertently released a batch of Lincoln cents lacking the ‘S’ mint mark.
This error occurred when a die intended for regular circulation, which did not bear the mint mark, was mistakenly used for proof coinage.
As a result, approximately 3,700 proof coins were struck before the mistake was identified. Subsequently, the Mint destroyed 145 of these error coins, leaving fewer than 200 in circulation today.
Significance of the Missing ‘S’ Mint Mark
The ‘S’ mint mark signifies coins minted at the San Francisco facility, especially for proof coins post-1968. Its absence on a proof coin is a rarity, making the 1990 No-S Proof Lincoln Cent the only proof cent from 1909 to date missing this crucial identifier. This distinct feature elevates its desirability among collectors.
Market Value and Auction Records
The scarcity of the 1990 No-S Proof Lincoln Cent has led to significant market interest. High-grade specimens, particularly those graded PR69 Deep Cameo (DCAM), have fetched impressive sums at auctions.
Notably, a PR69 DCAM coin achieved a sale price of $20,700 in 2007. While market fluctuations occur, the coin’s value remains substantial, with current estimates for PR69 DCAM specimens around $6,400.
Estimated Total Collection Value
Considering the existence of fewer than 200 specimens and an average value of approximately $500,000 per coin, the collective worth of all known 1990 No-S Proof Lincoln Cents approaches $99 million.
This estimation underscores the coin’s prominence in the numismatic community.
Identifying a 1990 No-S Proof Lincoln Cent
Collectors can identify this rare coin by examining the following features:
- Absence of ‘S’ Mint Mark: Located below the date on the obverse side, the missing ‘S’ is the primary identifier.
- Proof Characteristics: The coin should exhibit sharp details with a mirror-like background and frosted design elements, indicative of proof minting.
- Packaging: Many of these coins were originally distributed in 1990 Proof Sets or Prestige Proof Sets. Unopened or original packaging may enhance value.
