The 2011-S Lincoln Penny is worth anywhere from $3 in typical proof condition to over $100 for high-grade Deep Cameo specimens. While your everyday pocket change usually features the Philadelphia or Denver mint marks, finding an “S” mint mark from 2011 means you have a coin specially struck for collectors.
| Condition / Grade | Estimated Market Value |
|---|---|
| PR 65 (Standard Proof) | $3.00 – $5.00 |
| PR 69 Deep Cameo | $10.00 – $18.00 |
| PR 70 Deep Cameo (Perfect) | $40.00 – $110.00+ |
Understanding the 2011-S San Francisco Proof Penny
If you’ve recently sorted through a collection and found a shiny penny with a small “S” under the date, you are looking at a proof coin. Unlike the billions of pennies struck for circulation in Philadelphia and Denver, the 2011-S Lincoln Shield Penny was produced exclusively at the San Francisco Mint for inclusion in annual United States Mint Proof Sets. These coins were never intended to spend at the grocery store, which is why they look so different from the brown, scratched pennies in your pocket.
If you are unsure whether your coin is a proof or just a very shiny regular strike, using a top coin identifier app can help you distinguish between various minting techniques. The San Francisco Mint produced exactly 3,483,124 of these pennies in 2011. While three million might sound like a lot, it is a tiny fraction compared to the nearly 5 billion pennies struck in total that year.
To get an instant reading on your find, the CoinKnow app allows users to scan their coins and receive immediate historical data. Because these coins were handled with gloves and struck using polished dies, they feature a mirror-like background (fields) and frosted foregrounds (the portrait of Lincoln), a finish technically known as “Deep Cameo.”

The Shift to the Union Shield Design
The 2011-S Lincoln Penny belongs to the “Union Shield” series, which began in 2010. This modern design replaced the 2009 bicentennial themes and the long-running Lincoln Memorial reverse that Americans used for fifty years. The shield design was chosen to represent President Abraham Lincoln’s preservation of the United States as a single, united country.

The reverse features a union shield with 13 vertical stripes and a horizontal bar across the top. You’ll notice the inscription “E Pluribus Unum” (Out of many, one) and the denomination “One Cent.” Even though the design is common, the 2011-S version is special because of its limited mintage. Many people use CoinKnow to track the changing market prices for this specific design year.
Collectors often look for perfection in these modern coins. Because they were sold in plastic “slabs” or lenses from the Mint, most surviving copies are in high grades. However, minor spots or “haze” can develop over time, which significantly impacts the price. You can find detailed 2011-S Lincoln Penny price data by looking at auction records for graded specimens.

How Grading Affects 2011-S Lincoln Penny Value
In the world of coin collecting, “Grade” is everything. For a 2011-S penny, grades are measured on the Sheldon Scale from 1 to 70. Since these are proof coins, they are prefaced with “PR” or “PF.” A PR 60 coin might have some visible scratches or fingerprints from being removed from its original packaging. A PR 70 coin is considered flawless under 5x magnification.
Most 2011-S pennies you find in original sets will grade between PR 67 and PR 69. A PR 69 is very common and usually only worth a few dollars more than the cost of shipping. However, a PR 70 is the “holy grail” for modern builders of Registry Sets. The premium for a perfect grade can be ten times higher than a PR 69.
| Grade Level | Visual Characteristics | Value Range |
|---|---|---|
| PR 63-65 | Visible spots or light scratches | $2 – $4 |
| PR 68 | Nearly perfect, invisible flaws | $8 – $12 |
| PR 69 | Flawless to the naked eye | $15 – $20 |
| PR 70 | Perfect under magnification | $50 – $125 |
Comparing the 2011-S to P and D Mint Marks
It is vital to distinguish the San Francisco proof from the standard Philadelphia (no mint mark) and Denver (D) coins. If you found a 2011 penny in your change, it is almost certainly a 2011-P or 2011-D. These coins were minted by the billions and are generally only worth their face value of one cent unless they are in exceptionally high uncirculated grades.

Collectors using the CoinKnow app often find that while the S-mint coins are rarer, the P and D strikes in “Mint State 68” can actually be more valuable because they are so hard to find in perfect condition after being banged around in ballistic bags. To see how these compare, checking a 2011 penny value guide will show you that a high-grade 2011-D can sometimes fetch over $100 just like the proof.
The 2011-S, however, remains a favorite because of its aesthetic beauty. The contrast between the shiny “fields” and the frosted “relief” makes it a “Deep Cameo” (DCAM), which is the standard for modern San Francisco proofs. If your “S” penny looks dull or like a normal shiny penny, it may have been “impaired” by being circulated.
What to Look for: Are There 2011-S Errors?
While the US Mint has high quality control for proof coins, errors can still happen. Collectors look for “Doubled Dies,” which occur when the hub strikes the die multiple times at slightly different angles. While no major, high-value doubled die has been confirmed for the 2011-S specifically, there are minor “RPM” (Re-punched Mint Mark) varieties that specialists look for.

If you find a 2011 penny that looks like it has a “double” image on the date or “In God We Trust,” it could be worth significantly more than the standard value. Always use a jeweler’s loupe to inspect the coin. Most “doubling” found by beginners is actually “mechanical doubling,” which is a flat, shelf-like appearance caused by the machine vibrating, rather than a true doubled die.
| Error Type | Description | Potential Value |
|---|---|---|
| Off-Center Strike | Design is not centered on the coin | $50 – $200+ |
| Die Break (Cud) | A lump of metal where the die broke | $10 – $50 |
| Proof Impairment | Fingerprints or heavy cleaning | Face Value to $1 |
Summary: Should You Save Your 2011-S Penny?
If you find a 2011-S Lincoln Penny, the answer is a resounding yes! Even in lower proof grades, it is worth far more than one cent. It is a piece of numismatic history that represents the transition of the penny’s design into the 21st century. While it won’t make you rich enough to retire, it is a fantastic “gateway” coin for new collectors.
To keep its value, avoid touching the surfaces of the coin with your bare hands. The oils from your skin can cause permanent spots that lower the grade from a PR 70 to a PR 63 in just a few years. Store it in a PVC-free plastic flip or a dedicated coin album to preserve that beautiful San Francisco shine.
FAQ
Q: Why does my 2011 penny have an “S” but looks scratched?
A: This is likely an “impaired proof.” It was originally part of a collector set, but someone took it out and spent it. Once a proof coin enters circulation, its value drops significantly, often to just $0.50 or $1.00.

Q: Is the 2011-S penny made of real copper?
A: No. Like all Lincoln pennies since mid-1982, the 2011-S is made of a core of 99.2% zinc, which is then plated with a thin layer of pure copper. This is why you should never “clean” your penny, as you might rub through the copper layer.
Q: How can I sell my 2011-S Lincoln Penny?
A: If it is not professionally graded, your best bet is selling it on platforms like eBay or to a local coin shop. However, because the value is relatively low (under $20 for most), the shipping costs might be more than the coin is worth unless you have a “Perfect 70” specimen.
Q: What is the most expensive 2011 penny ever sold?
A: High-grade examples of the 2011-S in PR 70 Deep Cameo condition have sold at major auctions for over $150. Surprisingly, rare high-grade 2011-D (Denver) pennies in MS 68 condition have also fetched hundreds of dollars due to their rarity in that specific grade.
