The 1998-S Lincoln Penny is worth anywhere from $2 to $5 in typical proof condition to over $1,000 for rare “Close AM” business strike varieties. While most 1998 pennies in your pocket change are only worth one cent, the “S” mint mark signifies a special production made specifically for collectors.
Understanding the Special Nature of the 1998-S Proof Penny
The letter “S” below the date on your copper-looking coin indicates it was minted at the San Francisco Mint. Unlike the billions of 1998 pennies made in Philadelphia or Denver for daily commerce, the 1998-S was issued as a “Proof.” These coins were struck using polished dies and specially prepared blanks to create a mirror-like background and frosted details.
If you have found one of these in a coin folder or inherited a collection, you are looking at a piece of numismatic history. Finding a high-quality specimen is easier with a top coin identifier app, which can help you distinguish between a standard shiny penny and a genuine proof.
Most collectors possess these as part of a 1998 Proof Set. However, when these sets are broken up, individual pennies enter the secondary market. While common, they remain a staple for anyone trying to complete a full run of Lincoln Memorial cents. To accurately track your collection, using an app like CoinHix allows you to catalog each mint mark and condition grade instantly.
Current Market Value and Price Comparison Table
The value of a 1998-S penny is heavily dependent on its “Deep Cameo” (DCAM) status. This refers to the sharp contrast between the shiny fields and the white, frosted appearance of Lincoln’s portrait. Most 1998-S pennies graded PR69 or PR70—the highest possible grades—sell for a modest premium, but rare errors found within this year can skyrocket in price.

The Rare 1998-S Close AM Penny Variety
While most “S” pennies are proofs, a rare mistake occurred at the mint in 1998. The San Francisco Mint accidentally used a “Business Strike” reverse die (intended for normal circulating pennies) to strike a very small number of proof coins. Conversely, the Philadelphia mint accidentally used “Proof” dies to strike normal pennies.
The “Close AM” variety is the holy grail for 1998 penny hunters. On a standard 1998-S proof, the “A” and “M” in “AMERICA” should be clearly separated (Wide AM). If you find a 1998-S where the “A” and “M” are nearly touching at the base, you have discovered a rare transitional error.
For a detailed visual guide on these specific errors, checking a 1998 penny value guide is essential. These errors are often missed by the naked eye, leading many to spend them as regular pocket change. Using a high-resolution magnification tool or the CoinHix photo identification feature can help you spot these microscopic differences that signify a high-value coin.
Assessing the Condition and Surface Quality
When determining the 1998-S Lincoln Penny value, the surface quality is everything. Because these were struck with high pressure, any scratch, fingerprint, or spot of “milkiness” can drastically drop the price. Collectors look for “Red” (RD) designations, meaning the coin still retains at least 95% of its original orange-copper luster.
Fingerprint oils are acidic and can permanently etch the surface of a proof penny. If you find one, handle it only by the edges or wear cotton gloves. Even a tiny smudge can reduce a coin from a $50 specimen to a $1 specimen.
Many Americans find these in “Uncirculated Sets” that have been sitting in a drawer for decades. If the plastic packaging is intact, the coin is likely in Excellent condition. If you find one loose in a jar, it is likely “impaired,” meaning it has circulated, and its value will be closer to the lower end of the spectrum.
How to Sell Your 1998-S Penny and Next Steps
If you believe you have a high-grade 1998-S or the rare Close AM variety, your first step should be digital authentication. Professional grading by services like PCGS or NGC can cost $30 to $50, which isn’t worth it for a standard $3 proof coin. You should only consider professional grading if the coin appears to be a perfect PR70 or a confirmed error.
Start by using CoinHix to compare your coin against a database of known high-value sales. This gives you a baseline for negotiation if you decide to take the coin to a local dealer or list it on an auction site like eBay.
Remember that the market for modern pennies is very active. Many collectors are looking to complete their “Memorial Cent” sets, and a clean, beautiful 1998-S is always in demand. Keep your coins stored in PVC-free flips or capsules to preserve their value for years to come.
Frequently Asked Questions
Q: How can I tell if my 1998 penny is a Proof?
A: A 1998-S proof penny will have a distinct “S” mint mark under the date. It will also have a mirror-like, shiny background that reflects light like a glass mirror, while the raised parts (like Lincoln’s head) will appear frosted.
Q: Is a regular 1998 penny with no mint mark worth anything?
A: Most 1998 pennies without a mint mark (made in Philadelphia) are only worth face value. However, look for the “Wide AM” error on these; if the A and M in AMERICA are spaced apart, the coin could be worth $10 to $25.
Q: Are all 1998-S pennies rare?
A: While they were produced in lower numbers than regular pennies (about 2 million sets), they are not considered “rare” in the world of coin collecting. They are common in the collector market unless they are a perfect Grade 70 or a transition error variety.
Q: What is the most expensive 1998 penny ever sold?
A: High-grade error versions, such as a 1998-S “Close AM” in high grade, have sold at auction for over $1,000. Standard proofs usually top out around $50 to $100 if they are flawless “70” grades.
