What Makes the 1990 No S Lincoln Penny So Special
Most Lincoln pennies minted at the San Francisco Mint for proof sets carry a small “S” mintmark just below the date on the obverse side. That little letter tells collectors where the coin was made. In 1990, however, a small number of proof pennies were accidentally released without that mintmark — creating what’s known as the 1990 No S Proof Lincoln Penny.
This wasn’t supposed to happen. The U.S. Mint intended every proof penny in the 1990 proof sets to bear the “S” mintmark. Somewhere in the production process, a small batch slipped through without it. Estimates suggest fewer than 200 examples exist, though only a portion of those have been professionally certified. That extreme rarity is the engine behind the coin’s impressive value.
This isn’t your everyday penny error. It belongs to a prestigious category of modern U.S. proof errors that collectors and investors actively seek out. If you think you might have one, the first step is getting it properly authenticated.

How to Identify the 1990 No S Lincoln Penny
Identifying this coin takes a careful eye. Here’s what you need to look for:
– Date: The coin must read 1990.
– Mintmark: There should be NO “S” mintmark below the date. This is the defining feature.
– Proof quality: The coin should have sharp, cameo-style details — frosted devices on a mirror-like field. This is not a circulation coin. It came from a proof set.
– Condition: Most genuine examples grade from PR63 to PR69 on the Sheldon scale.
If your coin looks like a regular circulation penny, it’s likely not the rare No S version. The 1990 No S coin has the unmistakable, high-contrast look of a proof coin. You can cross-reference detailed 1990 penny value information by grade and variety to better understand what you’re looking at before sending it in for grading.
Always have a suspected 1990 No S Lincoln Penny certified by a reputable third-party grading service like PCGS or NGC. An uncertified coin will struggle to reach its full market value.

FAQ
Q: How do I know if my 1990 penny is the rare No S proof version?
A: Look for proof-quality surfaces — sharp details, frosted devices, and a mirror-like background. Then check below the date for the “S” mintmark. If it’s missing and the coin clearly has proof characteristics, you may have the rare variety. Send it to PCGS or NGC for authentication.
Q: How many 1990 No S Lincoln Pennies exist?
A: The exact number is unknown, but most experts estimate fewer than 200 examples are known, with only a portion of those certified by major grading services. This low population is a key reason the coin commands such high prices.
Q: Can I find a 1990 No S Lincoln Penny in circulation?
A: Almost certainly not. This coin originated exclusively in U.S. Mint proof sets sold directly to collectors. It was never intended for general circulation. Your best chance of encountering one is by searching through old proof sets from 1990 or buying through established coin dealers and auction houses.
