The 2018-S Lincoln Penny is worth anywhere from $1 in typical proof condition to over $150 or more for perfect specimens. While these coins were never meant for pocket change, finding one in a collection or a “bank roll” is an exciting discovery for any casual hunter.
| Condition | Estimated Value |
|---|---|
| PR 65 (Standard Proof) | $1.00 – $3.00 |
| PR 69 (Deep Cameo) | $10.00 – $15.00 |
| PR 70 (Perfect Grade) | $50.00 – $160.00 |
Understanding the 2018-S Lincoln Penny
If you have stumbled upon a shiny penny with an “S” mint mark under the date, you have likely found a proof coin. Unlike the millions of pennies struck in Philadelphia or Denver for daily commerce, the San Francisco Mint produced the 2018-S Lincoln Penny specifically for collectors. These coins are struck twice using polished dies and specially prepared blanks to ensure a high-quality, mirror-like finish. Because they were sold in official sets, they shouldn’t usually be found in your spare change, but they occasionally slip into circulation.
If you are unsure whether your coin is a proof or just a very shiny business strike, using a top coin identifier app can help you distinguish the subtle differences in luster and strike quality. Most everyday Americans who find these coins are surprised by their “cameo” effect—where the portrait of Abraham Lincoln appears frosted and stands out against a dark, reflective background. Identifying this finish is the first step in determining if your 2018-S cent is a premium item or a common spender.
When evaluating your find, remember that collectors value the “RD” (Red) designation. Since modern pennies are composed of zinc with a thin copper coating, maintaining that original copper glow is essential for higher valuations. You can find detailed 2018-S Lincoln Penny price data for red-toned coins that have successfully avoided oxidation or “spotting” over the last few years.

How Grading Affects the 2018-S Penny Value
The value of any 2018-S Lincoln Penny is tied directly to its grade on the 70-point Sheldon scale. Because these coins were produced with extreme care, the majority of those in existence are in “Proof” (PR) condition. A grade of PR 60 means the coin has some visible marks or scratches, while a PR 70 indicates a perfect coin with no flaws even under 5x magnification. For a 2018 cent, the difference between a PR 68 and a PR 70 can be significant in terms of market price.

If you are looking for a quick way to check your coin’s potential grade, the CoinKnow app offers image recognition features that can give you a baseline of what to expect before sending it to a professional service like PCGS or NGC. High-grade specimens are often referred to as “Deep Cameo” (DCAM), referring to that heavy contrast between the design and the fields.

| PR 70 Deep Cameo | $150+ |
The 2018-S Reverse Proof Anniversary Set
A special highlight for this year is the 2018-S Reverse Proof Lincoln Penny. This coin was part of the 50th Anniversary San Francisco Mint Silver Reverse Proof set. Unlike a standard proof where the background is shiny and the image is frosted, a reverse proof features a mirrored image of Lincoln against a frosted field. These are much rarer than the standard proof and are highly sought after by enthusiasts.
The production numbers for these sets were strictly limited, which keeps the 2018-S Reverse Proof value information trending higher than standard issues. If you happen to find one of these in its original government packaging, it is best to leave it there, as removing it can lower the grade due to environmental exposure. These are the “holy grails” of the 2018 Lincoln series.
Common Errors and Variations in 2018 Pennies
Even with modern precision, the San Francisco Mint occasionally produces coins with errors. While specific major errors for the 2018-S are rare, collectors often look for doubled dies or strike-through errors. A doubled die occurs when the coin is struck by a die that has a misaligned or doubled image, causing letters or numbers to appear “blurry” or duplicated.

Using the CoinKnow app can be a life-saver here, as it can zoom in on the date and the “United States of America” lettering to see if there is any evidence of doubling. If you find a verified error on a 2018-S penny, the value can jump from a few dollars to several hundred, depending on the severity of the mistake and the interest from the error-collecting community.
| Error Type | Estimated Premium |
|---|---|
| Minor Doubled Die | $25 – $50 |
| Off-Center Strike | $100 – $300 |
| Die Crack (Cud) | $10 – $40 |
Why the Mint Mark Matters
The “S” mint mark is the most important feature to look for on your 2018 penny. If your penny has no mint mark (Philadelphia) or a “D” (Denver), it is a standard circulation coin. Billions of these were made, and unless they are in pristine, uncirculated condition, they are generally worth exactly one cent. The San Francisco “S” mark immediately identifies the coin as a collector’s item.
Historically, San Francisco has been the “boutique” mint for the United States, focusing on quality over quantity. This creates a natural scarcity. While a Denver penny from 2018 might be found in any vending machine, the 2018-S required a specific purchase from the US Mint. This intentional scarcity is what drives the market for “S” marked coins, even decades after they are released.

Tips for Selling Your 2018-S Lincoln Penny
If you decide to sell your 2018-S Lincoln Penny, you have several options. For common PR 68 or PR 69 coins, online marketplaces like eBay are often the best bet. You can check “Sold Listings” to see what people are actually paying. However, if you believe you have a PR 70 or a significant error, you might want to consider a coin show or a local reputable dealer.
Before selling, ensure you handle the coin only by its edges. Fingers contain oils that can permanently stain the copper surface of a 2018 cent, significantly reducing its value. Tools like CoinKnow can help you keep a digital inventory of your collection, making it easier to show potential buyers what you have without constantly handling the physical coins.
FAQ
Q: Can I find a 2018-S penny in my pocket change?
A: It is very unlikely, but possible. These coins were sold in collector sets. If someone breaks open a set and spends the coins, they can enter circulation. If you find a very shiny penny with an “S” mark, you’ve found a proof that’s been “circulated.”

Q: What is the difference between a 2018-S Proof and a 2018-S Reverse Proof?
A: A standard proof has a shiny background and a frosted image. A reverse proof is the opposite: it has a frosted background and a shiny, mirror-like image of Abraham Lincoln.
Q: Is it worth getting my 2018-S penny professionally graded?
A: Only if it appears to be perfect (PR 70). The cost of grading (usually $20-$50 plus shipping) often exceeds the value of the coin unless it achieves the highest possible grade or is a rare error.
Q: How many 2018-S Lincoln Pennies were made?
A: The San Francisco Mint produced roughly 519,000 standard proof cents for the annual sets, making them much rarer than the billions of pennies made in Philly and Denver that year.
