Understanding the Unique Nature of the 1999-S Lincoln Penny
If you have found a 1999 penny with a small “S” directly under the date, you are looking at a Proof coin. Unlike the millions of pennies minted in Philadelphia or Denver for daily commerce, the San Francisco Mint produced these specifically for collectors. They were sold in official United States Mint Proof Sets, meaning they were never intended to be spent at a grocery store. To get a quick estimate on any coin you find, many collectors use a top coin identifier and value app to scan the details instantly.
The “S” mint mark signifies a higher level of craftsmanship. Proof coins are struck using specially polished dies and planchets (coin blanks), resulting in a mirror-like background and frosted details. Because they were issued in protective plastic lenses, a 1999-S Lincoln Penny should still look brand new. If you find one that is scratched or dull, it likely escaped its set and spent some time in circulation, which significantly lowers its collector value. Identifying these subtle differences is easy with the CoinKnow app, which helps novices distinguish between standard strikes and premium proofs.
Even though these were made for collectors, the 1999-S is not considered “rare” in the traditional sense, as over 3.3 million sets were produced. However, the value climbs sharply when a coin is “perfect.” Serious numismatists look for the PR 70 Deep Cameo (DCAM) designation, which represents a coin with no visible flaws even under 5x magnification. For everyday Americans, checking your old mint sets could reveal a hidden gem if the penny looks exceptionally clear and deep in its contrast.

How Condition and Grading Impact the 1999-S Value
Grading is the most significant factor in determining the price of a 1999-S penny. Since all proof coins start in “Mint State,” the scale used is the Sheldon Scale from 1 to 70. Most 1999-S pennies found in original packaging will grade around PR 67 or PR 68. At these levels, the coin is worth a few dollars. However, jumping just two points to a perfect PR 70 can increase the price by hundreds of dollars. The 1999 penny auction prices and grading data show that high-quality specimens are highly sought after by Registry Set collectors.

Another term you will see often is “Deep Cameo.” This refers to the visual contrast between the shiny, reflective fields (the flat parts) and the frosted devices (Lincoln’s portrait and the Lincoln Memorial). In 1999, the US Mint was quite efficient at producing this contrast, so most 1999-S pennies are Deep Cameos. If you have a coin that lacks this frostiness, it might actually be more unusual, though not necessarily more valuable. For those unsure of their coin’s grade, CoinKnow offers a streamlined way to compare your coin against high-resolution images of graded examples.
Evaluating the condition yourself involves looking for “hairlines”—tiny scratches caused by cleaning or poor handling. Even sliding a coin across a table can drop it from a premium grade to a standard one. Always handle your 1999-S by the edges and never touch the face of the coin, as the oils from your fingers can cause permanent spotting over time, effectively ruining its premium value.

| Grade Designation | Visual Characteristics | Rough Value |
|---|---|---|
| PR 67 DCAM | Strong contrast, few tiny spots | $3 – $5 |
| PR 68 DCAM | Almost perfect, very eye-appealing | $7 – $12 |
| PR 69 DCAM | Visually perfect to the naked eye | $15 – $25 |
| PR 70 DCAM | Flawless under magnification | $150 – $450+ |
The Famous 1999 Wide AM Penny Variety Explained
While the 1999-S is a proof coin, there is a legendary “error” or “variety” associated with 1999 pennies that every collector should know about: the Wide AM. Generally, this variety is found on Philadelphia (no mint mark) coins, but the concept is vital for understanding 1999 penny values. In 1999, some pennies were accidentally struck with a die intended for Proof coins. On a standard penny, the letters “A” and “M” in “AMERICA” on the reverse should be touching. On the Wide AM variety, they have a clear space between them.
Interestingly, for the 1999-S Proof penny, the “Wide AM” is actually the standard design. Because Proof coins were supposed to have the Wide AM design, finding a 1999-S with a “Close AM” would be the ultimate discovery. To date, these are extremely rare or non-existent in the 1999-S series, but collectors always keep an eye out. You can find more details about 1999 penny varieties and errors online to ensure you aren’t overlooking a multi-thousand dollar rarity.
Identifying these varieties requires a steady hand and a good magnifying glass. If you find a 1999 penny in your change that has a wide gap between the A and M, you might have the Philadelphia Wide AM version, which is worth $100 to $500 depending on its condition. It is the most valuable “common” error of that year. Using an app like CoinKnow can help you zoom in on these specific areas to see the spacing clearly without needing an expensive jeweler’s loupe.

Common Errors Found on 1999-S Proof Pennies
Even though Proof coins undergo a rigorous inspection process, errors can still slip through the cracks at the San Francisco Mint. These errors are what drive the “everyday” value of a coin into the triple or quadruple digits. One of the most common errors to look for is a “Double Die.” This occurs when the hub strikes the die twice at slightly different angles, creating a doubled appearance on the lettering or the date.
Another rare but possible error on a 1999-S is a “Clipped Planchet,” where the coin is missing a circular slice, or “Off-Center strikes,” where the design is pushed to one side. Because Proof sets are hand-packaged, these errors are rarely found, making them highly valuable. If you happen to find a 1999-S that looks “wrong”—perhaps the coloring is off or the shape is irregular—it is worth having it appraised by a professional or checking it against a database of known mint errors.
| Error Type | What to Look For | Estimated Value |
|---|---|---|
| Double Die Obverse | Doubling on “In God We Trust” or Date | $50 – $200 |
| Die Planching / Spots | Black or “milk” spots on the surface | Decreases Value |
| Off-Center Strike | Design not centered on the coin | $100+ |
Where to Sell Your 1999-S Lincoln Penny
If you have determined that your 1999-S penny is in top-tier condition or features a rare error, your next step is deciding where to sell. For coins worth only a few dollars, local coin shops or eBay are your best bets. Because shipping can cost more than the coin itself, selling as part of a larger collection or set is often more profitable. However, if you believe you have a PR 70 or a significant error, professional grading by services like PCGS or NGC is recommended.

Graded coins sell for significantly more because the “grade” is guaranteed by a third party. A 1999-S certified as a PR 70 Deep Cameo can be sold through major numismatic auction houses like Heritage Auctions or GreatCollections. For the average person, the easiest way to start is by getting an initial valuation through a mobile tool and then visiting a reputable local dealer for a second opinion. Always remember that “raw” (ungraded) coins will almost always sell for less than their “slabbed” (graded) counterparts.
Summary of the 1999-S Penny Market
In the world of modern coin collecting, the 1999-S Lincoln Penny remains an accessible and beautiful piece of American history. While it may not make you a millionaire overnight, finding a perfect specimen can provide a nice payday. The key is in the details: the “S” mint mark, the Deep Cameo contrast, and the absence of any tiny surface scratches. Whether you are a seasoned collector or someone who just found an old mint set in the attic, the 1999-S is a testament to the artistry of the San Francisco Mint.
Always keep your 1999-S in its original protective holder if possible. If the holder is cracked, move the coin to a PVC-free plastic flip to prevent “environmental damage.” As the years pass, perfect 70-grade coins become harder to find, potentially increasing the value of the few remaining flawless examples. Happy hunting, and keep your eyes peeled for those mirrored surfaces!
FAQ
Q: Why does my 1999 penny have an “S” but looks like copper?
A: All Lincoln pennies struck in 1999 are actually copper-plated zinc. Even though the 1999-S is a Proof coin, it is made of the same materials as regular pennies. Its “special” status comes from the way it was polished and struck, not from a different metal composition.

Q: Can I find a 1999-S penny in my pocket change?
A: It is very rare but possible. These are called “Proof Impaired” coins. They usually end up in circulation if someone breaks open a mint set to spend the money. If found in change, they are usually scratched and only worth about $0.10 to $0.50.
Q: Is the 1999-S penny made of silver?
A: No, the 1999-S Lincoln Penny is not silver. While the US Mint produces Silver Proof Sets that include silver quarters, dimes, and half dollars, the penny and nickel in those sets remain composed of their standard base metals.
Q: How can I tell if my 1999-S is a “Deep Cameo”?
A: Look at the contrast. If Lincoln’s portrait looks like it has a white, frosted matte finish while the background looks like a dark, perfect mirror, it is a Deep Cameo. If the contrast is weak, it is just a standard “Proof.”
