1991-S Lincoln Penny Value How Much Is It Really Worth
The 1991-S Lincoln Penny is worth anywhere from $1 to $5 in typical circulated condition, but certified proof examples can fetch $3 to $10 or more depending on grade and eye appeal. If you found one in a old collection or coin roll, you’re in the right place — let’s break down exactly what it’s worth.
The 1991-S penny is a special coin, but it’s not one you’d normally find in everyday pocket change. The “S” mintmark tells you it was struck at the San Francisco Mint, and unlike regular business-strike pennies, San Francisco made the 1991-S exclusively as a proof coin for collector sets. That means it was never intended for circulation. If you’re trying to figure out whether your coin is genuine and what condition it’s in, a free coin identifier app can be a great starting point — it helps you quickly read mintmarks and assess surface quality before you dive deeper into research.
What Makes the 1991-S Penny Different from Other 1991 Pennies
Most pennies you find in change from 1991 came from either the Philadelphia Mint (no mintmark) or the Denver Mint (D mintmark). Those are everyday business-strike coins produced by the hundreds of millions. The 1991-S, on the other hand, was produced at the San Francisco Mint specifically for inclusion in the annual U.S. Proof Set. The total mintage for the 1991-S Lincoln Cent was approximately 2,867,787 — which sounds like a lot, but compared to the over 5 billion combined business-strike pennies made that year, it’s relatively modest.
Because proof coins are struck with specially polished dies and planchets, they have a mirror-like background field and sharp, frosted design elements. The 1991-S Lincoln cent features the familiar portrait of Abraham Lincoln on the obverse and the Lincoln Memorial on the reverse — the classic design that ran from 1959 to 2008. These coins were carefully handled from the start, so most surviving examples are still in excellent condition.
1991-S Lincoln Penny Value by Grade
Value for the 1991-S penny is almost entirely tied to its proof grade. Because these coins were made for collectors, you’ll almost always see them graded on the PR (Proof) or PF scale by services like PCGS or NGC. Here’s a look at typical values:
| Grade | Description | Estimated Value |
|---|---|---|
| PR 65 RD | Gem Proof, full red | $3 – $5 |
| PR 66 RD | Gem+ Proof, full red | $4 – $6 |
| PR 67 RD | Superb Gem Proof | $5 – $8 |
| PR 68 RD | Near-perfect Proof | $8 – $15 |
| PR 69 DCAM | Deep Cameo, near flawless | $15 – $30+ |
| PR 70 DCAM | Perfect Proof (rare) | $50 – $100+ |

How to Tell If Your 1991-S Penny Is Worth More
The biggest value driver for the 1991-S Lincoln cent — beyond the grade — is the cameo contrast. Proof coins can be graded as Cameo (CAM) or Deep Cameo (DCAM), which refers to the frosted look on the raised design against the mirror-like fields. Deep Cameo examples are the most desirable and command a premium over regular proof coins at the same numeric grade.
You’ll also want to check for any signs of damage: hairlines from improper cleaning, spots, or hazy toning can all reduce value significantly. Never clean your coins — even a gentle wipe can leave microscopic scratches that drop a coin’s grade. If your coin is still in its original government proof set packaging, that’s a good sign it’s been protected all these years. CoinKnow is a handy app that can help you evaluate the visual quality of your coin’s surfaces using your phone camera and get an instant estimate before consulting a professional dealer.
Should You Get Your 1991-S Penny Graded?
Honestly, for most 1991-S Lincoln cents, professional third-party grading through PCGS or NGC probably isn’t worth the cost unless you believe you have a PR 68 DCAM or higher. Grading fees typically start around $20–$30 per coin, and for a coin worth $5 to $8, the math doesn’t work in your favor. However, if you have a coin that looks absolutely flawless — super-sharp cameo contrast, zero visible hairlines, blazing red color — it might be worth submitting to see if it comes back as a PR 69 or PR 70 DCAM, which can sell for real money.
If you have a whole proof set from 1991, the set itself in its original box and packaging typically sells for $5 to $12, making it an easy and convenient way to sell without cracking out individual coins.

FAQ About the 1991-S Lincoln Penny
Q: Is the 1991-S penny rare?
A: It’s not considered rare by most collector standards — nearly 2.9 million were made. However, it is scarcer than regular business-strike 1991 pennies, and high-grade DCAM examples in PR 69 or PR 70 are genuinely hard to find.
Q: Can I find a 1991-S penny in circulation?
A: It’s very unlikely. The 1991-S was made exclusively for proof sets and never released into general circulation. If you do find one in change, it was likely removed from a proof set at some point, which means it’s probably been handled and may show wear or contact marks.
Q: How do I use CoinKnow to check my 1991-S penny?
A: Download the CoinKnow app, select Lincoln Cents from the catalog, enter the year and mintmark, and the app will show you current market values by grade along with comparison images so you can estimate where your coin might fall on the grading scale.
