1990-S Lincoln Penny Value What It’s Worth and Why Collectors Care
The 1990-S Lincoln Penny is worth anywhere from $3 in average condition to over $10 in top certified grades, with proof versions being the most sought-after coins from this year. If you found one in a old collection or coin roll, you’re in the right place to learn exactly what you’ve got.
Whether you’re a casual collector or just someone who stumbled across an old penny, using a free coin identifier app is one of the easiest ways to get started identifying what you have before diving into values. Once you know what you’re looking at, understanding the details makes all the difference.
What Makes the 1990-S Lincoln Penny Special
The 1990-S Lincoln Penny was struck at the San Francisco Mint, and that little “S” mintmark is the key to its identity. Unlike the regular business-strike pennies made at Philadelphia and Denver that year, the San Francisco Mint produced 1990 pennies almost exclusively as proof coins — meaning they were specially made for collectors, not for everyday pocket change.
Proof coins are struck using polished dies and specially treated planchets, giving them a mirror-like background and sharp, frosted design details. They come in sealed proof sets and are rarely found in circulation. If you have a 1990-S penny, there’s a very good chance it came from one of these official U.S. Mint proof sets.
What makes this coin even more interesting to collectors is the famous 1990 No-S Proof Lincoln Penny — a rare error coin that was accidentally struck without the mintmark. But more on that in a moment.
1990-S Lincoln Penny Value by Grade and Type
For most 1990-S Lincoln Pennies, value is tied closely to their condition and whether they’re standard proof or a special variety. Proof coins in perfect condition (graded PR-69 or PR-70 by PCGS or NGC) command the highest prices.
Here’s a quick breakdown of typical values:
| Type | Grade | Estimated Value |
|---|---|---|
| 1990-S Proof | PR-65 | $3 – $5 |
| 1990-S Proof | PR-69 | $8 – $15 |
| 1990-S Proof | PR-70 DCAM | $50 – $100+ |
| 1990 No-S Proof Error | PR-69 | $2,500 – $4,000+ |

The Famous 1990 No-S Proof Penny Error
No conversation about the 1990-S Lincoln Penny is complete without mentioning the legendary No-S error. In 1990, a small number of proof pennies were accidentally struck with a die that had not been punched with the “S” mintmark. These coins went unnoticed until they reached collectors, and once the error was discovered, the numismatic world took notice fast.
Only around 200 examples are believed to exist, making the 1990 No-S Proof Lincoln Penny one of the most valuable modern U.S. coin errors. Depending on grade, certified examples regularly sell for $2,500 to over $4,000 at major coin auctions. In top grades, prices can go even higher.
If you think you have a 1990 proof penny without an “S” mintmark, get it authenticated by PCGS or NGC before assuming it’s the real thing. Unfortunately, the mintmark can sometimes be faint or worn, so professional certification is essential.
How to Check Your 1990-S Penny’s Condition and Value
Condition is everything when it comes to coin values. CoinKnow is a great tool for everyday collectors who want to quickly assess what they have. The app helps you identify coins by photo, compare grades, and estimate values — all from your phone. It’s especially useful if you’re working through a collection and don’t want to haul coins to a dealer just yet.
For the 1990-S proof penny, look for the following in good examples:
– Sharp, well-defined details on Lincoln’s portrait
– Mirror-like fields (the flat background areas)
– Frosted, cameo contrast on the design elements
– No spots, scratches, or cloudiness
Coins that show any hazing or handling are graded lower and worth less. If yours is still in the original sealed proof set, that’s the best case scenario — it keeps the coin protected and verifiable.

Tips for Selling or Keeping Your 1990-S Lincoln Penny
If your 1990-S penny is a standard proof in decent shape, it may not be worth a huge amount — but it’s still a collectible coin worth preserving. Keep it in a coin flip, 2×2 holder, or its original proof set packaging.
If you believe you have the No-S error variety, do not clean it under any circumstances. Cleaning a coin destroys its numismatic value. Instead, take it straight to a professional grading service or show it to a reputable coin dealer.
CoinKnow can also help you research comparable sales and understand where your coin fits in the market before you decide to sell. Having that knowledge puts you in a much better position when negotiating with dealers or listing on platforms like eBay.
For most people, the 1990-S Lincoln Penny is a small but satisfying piece of American coin history — and if you happen to have the No-S variety sitting in a drawer somewhere, it could be worth a very pleasant surprise.

FAQ
Q: How do I know if my 1990 penny is the rare No-S error?
A: Look under magnification at the area just below the date on the obverse (front). The “S” mintmark should appear as a small letter to the right of the “9” in 1990. If there is no mintmark at all and the coin is a proof (mirror-like finish), it could be the rare error. Have it authenticated by PCGS or NGC to confirm.
Q: Is the 1990-S Lincoln Penny rare?
A: The standard 1990-S proof penny is not especially rare — millions were made as part of proof sets. However, the 1990 No-S Proof Penny is extremely rare, with only around 200 known examples, making it one of the most valuable modern Lincoln cent errors.
Q: Can I use CoinKnow to identify and value my 1990-S penny?
A: Yes! CoinKnow is designed for exactly this kind of situation. You can photograph your coin, get an identification, and see current estimated values — all without needing expert knowledge. It’s a great starting point before consulting a professional dealer or grading service.
