Understanding the Unique Status of the 1999-S Proof Penny
If you have found a penny dated 1999 with a small “S” mint mark under the date, you are holding a “Proof” coin. Unlike the billions of pennies minted in Philadelphia or Denver for daily commerce, the San Francisco Mint produced these specifically for collectors. They were originally sold in protective plastic sets, featuring a mirror-like finish and sharp details.
However, many of these sets get broken open over time, and some of these shiny coins end up in change jars. If you aren’t sure if your coin is a proof or just a very shiny business strike, using a top coin identifier app can help you distinguish the strike type instantly.
The CoinKnow app is particularly useful here, as it uses high-resolution image recognition to spot the distinctive frost on the portrait of Abraham Lincoln that defines the 1999-S. Because these coins were never intended to circulate, finding one in “the wild” is a rare treat.

Current Market Value for 1999-S Lincoln Cent Proofs
The value of a standard 1999-S Lincoln Penny is heavily dependent on its “Deep Cameo” (DCAM) effect. This refers to the contrast between the frosted design and the mirror-like fields (the flat background). Most 1999-S pennies found today still retain most of this luster, but scratches or fingerprints can lower the price significantly.
For most people, a 1999-S penny is worth a few dollars. However, serious collectors look for “Perfect 70” grades. You can track the current auction prices for 1999 Lincoln pennies to see how much the market fluctuates based on these tiny details.
| Appointed Grade | Average Selling Price |
|---|---|
| Proof 63 (Slightly impaired) | $1.50 |
| Proof 67 (Great condition) | $7.00 |
| Proof 69 (Nearly flawless) | $22.00 |
| Proof 70 (The Gold Standard) | $115.00 |
The Rare 1999-S “Close AM” Variety Worth Thousands
The real excitement regarding the 1999-S Lincoln Penny Value lies in a rare minting error known as the “Close AM” variety. In a normal 1999-S proof penny, the letters “A” and “M” in the word “AMERICA” on the reverse should be clearly separated (Wide AM). This was the standard design for proof dies in 1999.

However, a few proof coins were struck using “Business Strike” dies intended for Philadelphia or Denver pennies. On these dies, the “A” and “M” are nearly touching at the bottom. This mistake created one of the modern “Holy Grails” of penny collecting.
If you suspect you have one of these, CoinKnow can help you zoom in to see the gap between the letters. Finding a verified 1999-S Close AM can change your financial day, as these have sold for over $2,000 in high grades. You can find more comprehensive 1999-S value details through dedicated numismatic databases.

Key Features to Look For on Your 1999-S Penny
When evaluating your coin, you need to look at more than just the date. The 1999-S is part of the “Memorial” series, featuring the Lincoln Memorial on the back. Since it is a proof coin, the finish should be noticeably different from a standard penny.
Check for the “S” mint mark under the date. If the “S” is blurry or blob-like, it might be a filled die error. Also, look at the initials of the designer, Frank Gasparro (FG), located to the right of the Memorial steps. On the rare Close AM variety, the “FG” initials are usually further away from the building than on the Wide AM variety.
Taking a clear photo and uploading it to CoinKnow allows the app’s AI to analyze these specific markers for you. Even if it isn’t the rare error, a 1999-S in pristine condition is still a piece of history worth preserving in a flip or capsule.

How Condition Influences the Price of 1999 Pennies
Condition is everything in the world of coin collecting. For the 1999-S, the coin starts at a “Proof” grade, but its state can deteriorate if it has been handled. Coins are graded on a scale of 1 to 70. A 1999-S with a grade of PR-60 might have scuff marks or “haze” on the surface, making it worth only its face value or a few cents to a curious collector.
In contrast, a PR-70 coin is flawless even under 5x magnification. Because the San Francisco Mint produces these with such care, many 1999-S pennies are found in 68 or 69 condition. This means the jump in value between a 69 and a 70 is enormous because collectors pay a premium for perfection.
If you find a 1999-S in a roll of pennies from the bank, it is likely “impaired.” This means it has circulated and lost its mirror finish. While it won’t fetch a high price at auction, it is still a “keeper” for most hobbyists because it’s much rarer to find in circulation than a Denver or Philly penny.
Comparing the 1999-S to Other 1999 Pennies
To understand why the 1999-S is special, you have to look at its siblings from the same year. The 1999 Philadelphia (no mint mark) and 1999 Denver (D) pennies were minted by the billions. These are the ones you see in your pocket every day.

The values for these standard coins are generally just one cent unless they are in exceptional “Mint State” condition. However, 1999 was a “transitional” year for the Mint, leading to several errors across all mint facilities. This makes 1999 one of the most interesting years for modern penny hunters.
| Mint Location | Mintage Quantity | Standard Value (MS65) |
|---|---|---|
| Philadelphia (No Mark) | 5,237,600,000 | $1.00 – $3.00 |
| Denver (D) | 6,360,065,000 | $1.00 – $3.00 |
| San Francisco (S) | 3,347,966 | $5.00+ |
Final Tips for Your 1999-S Lincoln Penny
If you believe you have a valuable 1999-S, the first rule is: Do not clean it. Rubbing a proof coin with a cloth or using chemicals can instantly destroy its numismatic value. Even a soft tissue can leave hairline scratches on the delicate mirror surface of a proof penny.
Store your coin in a PVC-free plastic holder or a cardboard 2×2 flip. If you think you’ve found the “Close AM” variety, your next step should be to have it “attributed” or certified by a professional grading service like PCGS or NGC. Before spending money on grading fees, check it against the high-quality photos in a coin app to ensure it’s a strong candidate.
The 1999-S remains a favorite for collectors because it represents the peak of modern minting technology, while still hiding one of the most famous errors of the last 30 years. Whether it’s worth $3 or $3,000, it’s a fascinating piece of the American story.
FAQ
Q: Why is my 1999 penny shiny but has no “S” mint mark?
A: If it has no mint mark, it was made in Philadelphia. If it’s very shiny, it might be an “Uncirculated” coin from a mint set, or it might just be a very clean penny that hasn’t spent much time in circulation. These are generally worth face value unless in perfect condition.

Q: How many 1999-S Close AM pennies exist?
A: While the exact number is unknown, experts estimate that only a few dozen to a couple of hundred exist. They are significantly rarer than the regular Wide AM version, which is why they command such high prices.
Q: Can I find a 1999-S penny in my pocket change?
A: It is possible, but very unlikely. Standard proof coins are occasionally spent by people who don’t know their value, but because they look so different (highly mirrored), they are usually pulled out of circulation quickly by observant collectors.
Q: What is the highest price ever paid for a 1999-S Penny?
A: A perfect PR-70 Deep Cameo specimen of the 1999-S Close AM rare variety sold at auction for over $2,000. Standard PR-70 coins without the error usually sell for between $100 and $200.
