1998-S Lincoln Penny Value: How Much Is Your Proof Coin Worth?

The 1998-S Lincoln Penny is worth anywhere from $1 in typical proof condition to over $500 for a perfect specimen. While these coins weren’t meant for your pocket change, finding one can be an exciting discovery for any casual collector hoping to turn “pocket trash” into real profit.

Condition / Grade	Estimated Value
PR 65 (Deep Cameo)	$2.00 – $5.00
PR 69 (Deep Cameo)	$15.00 – $25.00
PR 70 (Perfect Grade)	$350.00 – $550.00

What Makes the 1998-S Lincoln Penny Unique?

The “S” mint mark on your 1998 Lincoln penny indicates that it was struck at the San Francisco Mint. Unlike the pennies you use at the grocery store, which are minted in Philadelphia (no mint mark) or Denver (“D” mark), the San Francisco coins from this year were produced exclusively as “Proof” coins.

If you’ve found one of these in your change, you might be wondering how it got there. Proof coins are specially prepared for collectors using polished dies and planchets, resulting in a mirror-like finish and sharp details. If you aren’t sure if your coin is a proof or just a shiny regular strike, using a top coin identifier app can help you distinguish the manufacturing process and minting origin instantly.

Most 1998-S pennies were sold in official United States Mint Proof Sets. However, over the years, many of these sets were broken open, and the individual coins sometimes found their way into circulation. Even if your coin has lost some of its original luster, it still carries a premium over its face value because of its proof status. To get an accurate reading on current market trends, the CoinKnow app is a fantastic resource for checking real-time sales data.

Grading the 1998-S Lincoln Memorial Cent

For collectors, the value of a 1998-S penny is almost entirely determined by its “grade” or condition. Because these were produced with extra care, most 1998-S pennies are expected to be in pristine condition. A grade of PR 69 (meaning nearly perfect) is very common, which keeps the price low for those specific coins.

However, the leap from PR 69 to PR 70—the perfect grade—is where the real money is made. A perfect PR 70 coin shows absolutely no scratches, fingerprints, or manufacturing flaws, even under 5x magnification. Because so few coins achieve this status, professional collectors are willing to pay a premium. You can check the current 1998-S penny price guide to see how much of a difference one grade point can make in the final sale price.

Grade Designation	Visual Description	Market Demand
PR 60-64	Noticeable prints or light scratches	Low ($1)
PR 65-68	Attractive, mirror-like, minor flaws	Moderate ($5)
PR 69 DCAM	Virtually flawless to the naked eye	High ($20)
PR 70 DCAM	Completely flawless under magnification	Extreme ($450+)

Identifying the Deep Cameo (DCAM) Effect

When looking at a 1998-S penny, you will often see the term “DCAM” or “Deep Cameo.” This refers to the visual contrast on the coin. On a Deep Cameo coin, the raised images (like Abraham Lincoln’s bust and the Lincoln Memorial) have a frosted, matte appearance, while the flat background (the “field”) is highly polished and reflective like a mirror.

During the 1990s, the San Francisco Mint had perfected this process, so almost all 1998-S pennies are considered Deep Cameo. If you find one that lacks this contrast—perhaps because it has been worn down in circulation—its value drops significantly toward the base price of a dollar or less.

If you are unsure whether your coin’s frosting is thick enough to qualify for a high-value designation, using CoinKnow can provide side-by-side photo comparisons. Understanding how to value 1998 pennies requires a keen eye for this contrast, as it is a major requirement for any coin intended for high-end auction houses.

Rare 1998 Penny Varieties to Watch For

While the 1998-S Proof is the star of the San Francisco mint, there is another 1998 variety that drives collectors wild: the “Wide AM” error. This error occurs on business-strike pennies (those without an ‘S’ mark, mostly from Philadelphia).

On a normal 1998 penny, the letters “A” and “M” in the word “AMERICA” on the reverse side should be almost touching. However, due to a mistake where a proof die was used for a regular coin, some pennies have a distinct space between the A and the M. This is known as the Wide AM variety.

Variety Type	Mint Mark	Average Value
1998 Wide AM	None (Philly)	$10 – $100
1998 Close AM	All	Face Value / $0.01
1998-S Proof	S	$1 – $500

This error is proof that even common years like 1998 can hold hidden treasures. If you have a jar of pennies, it’s worth taking a magnifying glass to the reverse of every 1998 coin you find. While the 1998-S is more of a “planned” collectible, the Wide AM is a true “treasure in your pocket” scenario.

How to Handle and Store Your 1998-S Penny

If you believe you have a high-grade 1998-S Lincoln Penny, you should handle it with extreme care. The surfaces of proof coins are incredibly sensitive. A single fingerprint can leave oils that eventually “eat” into the copper-plated zinc surface, creating permanent black spots or “toning” that collectors may dislike.

Always hold the coin by its edges, preferably using cotton gloves. If the coin is currently loose, place it in a PVC-free plastic flip or a cardboard “2×2” holder. This prevents the coin from getting scratched by other coins. For those who want to build a serious collection, CoinKnow offers a digital inventory feature where you can track the condition and estimated value of your coins as the market fluctuates.

Remember, cleaning a coin is the fastest way to destroy its value. If your 1998-S looks a bit dull, leave it as it is. Collectors prefer an honest, aged coin over one that has been scrubbed with chemicals, which leaves microscopic scratches that professional graders will spot immediately.

Summary of 1998 Penny Value Factors

To sum it up, the 1998-S penny is a beautiful example of modern minting technology. While it is not “rare” in the sense that millions were made, it is rare to find one in perfect, flaw-free condition.

The most valuable 1998-S pennies will always be those that are certified by professional grading services like PCGS or NGC. If your coin has a deep, mirror-like finish and looks like it just came out of a fresh mint set, it might be worth the investment to have it graded. For the casual finder, keep an eye on the “S” mark and the spacing of the “AM” on the reverse—you might just find a coin worth significantly more than a cent!

FAQ

Q: Why does my 1998 penny have an ‘S’ on it?

A: The ‘S’ stands for the San Francisco Mint. In 1998, this mint only produced “Proof” coins for collectors. These were not intended for general circulation but are sometimes found in change if a collector’s set was broken apart.

Q: Is a 1998-S penny made of real copper?

A: Not entirely. Like all Lincoln pennies made after mid-1982, the 1998nd penny is composed of a core of 97.5% zinc, with a thin outer plating of 2.5% copper. This is why you should never use chemicals to clean them, as the copper layer is very thin.

Q: How can I tell if my 1998 penny is a “Wide AM” error?

A: Look at the word “AMERICA” on the back. On a normal coin, the A and M are almost touching at the bottom. On the Wide AM error, there is a clear, visible gap between the two letters. This error is typically found on Philadelphia minted coins (no mint mark).

Q: What is the most a 1998-S penny has ever sold for?

A: High-grade examples in PR 70 Deep Cameo condition have sold at auction for prices ranging from $300 to over $500 depending on the current demand and the specific grading service that certified the coin.
