The 2004-S Lincoln Penny is worth anywhere from $3 in typical Proof condition to over $500 for flawless Deep Cameo specimens. While your pocket change usually holds common 2004 pennies, the “S” mint mark signifies a special production meant for collectors that can carry a surprising premium.
| Condition / Grade | Estimated Value |
|---|---|
| PR 65 Deep Cameo | $3.00 – $5.00 |
| PR 67 Deep Cameo | $8.00 – $12.00 |
| PR 69 Deep Cameo | $15.00 – $25.00 |
| PR 70 Deep Cameo (Perfect) | $250.00 – $550.00 |
Understanding the San Francisco Mint 2004-S Lincoln Penny
If you have found a penny from 2004 with a tiny “S” below the date, you are looking at a Proof coin. Unlike the billions of pennies minted in Philadelphia or Denver for daily commerce, the San Francisco Mint produced these specifically for annual Proof Sets. These coins were never intended to touch a cash register or a vending machine. Because they were handled with extreme care by the Mint, most surviving examples are in beautiful condition.
To accurately identify your coin and check for rare variations, many collectors use a top coin identifier app to get instant results. By using CoinKnow, you can simply take a photo of your penny to see if it matches the specific strike characteristics of the 2004-S Proof.
The 2004-S Lincoln Penny features the classic design by Victor David Brenner on the obverse and Frank Gasparro’s Lincoln Memorial on the reverse. Its composition is copper-plated zinc, which makes it susceptible to “zinc rot” if stored in damp conditions. Seeing an “S” mint mark on a modern penny is an immediate sign that the coin was once part of a collector’s set before somehow finding its way into circulation.

The Difference Between Proof and Business Strikes
To understand the 2004-S Lincoln Penny value, you must first distinguish between a “Business Strike” and a “Proof Strike.” Business strikes (from Philadelphia or Denver) are made quickly for mass circulation. Proof strikes, however, are struck at least twice using polished dies and planchets. This results in a mirror-like background (the field) and a frosted appearance on the portrait of Lincoln (the device).
When you look at the 2004-S Lincoln Penny auction records, you will notice the abbreviation “PR” (Proof) or “PF” instead of “MS” (Mint State). A “Deep Cameo” (DCAM) designation is the gold standard for these coins, indicating a sharp contrast between the shiny field and the white, frosted portrait.

If you find a 2004 penny without an “S” mint mark, or one with a “D” (Denver), it is likely only worth its face value unless it is in pristine, uncirculated condition. The CoinKnow app can help you distinguish these mint marks if they are worn down or dirty from being in your pocket.
Official Mintage and Rarity Factors
The mintage for the 2004-S Proof Penny was 2,965,422. While nearly 3 million might sound like a lot, compare that to the nearly 4.8 billion pennies struck in Philadelphia that same year. The relatively low supply makes the 2004-S a constant target for collectors building “Dansco” albums or registry sets.

| Mint Location | Mint Mark | Mintage Quantity |
|---|---|---|
| Philadelphia | None | 4,835,200,000 |
| Denver | D | 4,616,000,000 |
| San Francisco (Proof) | S | 2,965,422 |
Because these were sold in protective plastic lenses, “finding” one in your loose change is rare. These are called “Impaired Proofs.” An impaired proof that has been scratched or dulled by circulation will lose much of its collector value, often dropping to just $0.25 to $1.00. However, if you have a 2004-S that is still in its original Mint packaging, it maintains its premium.
Grading and the Pursuit of the PR70 Perfect Grade
In the world of coin collecting, the “Grade” is everything. For the 2004-S, most coins will grade at PR68 or PR69. Because the Minting process was so refined by 2004, these high grades are common. However, the jump in value between a PR69 and a PR70 (a perfect coin) is massive.
A PR69 Deep Cameo might sell for roughly $15, but a PR70 Deep Cameo—certified by professional services like PCGS or NGC—can fetch several hundred dollars. Collectors often use the CoinKnow app to zoom in on the surfaces of their coins to check for microscopic “carbon spots” or tiny hairline scratches that would prevent a perfect grade.

Detailed current 2004 Lincoln penny market values show that even though there are many Proofs available, the demand for “Registry Set” quality coins keeps the prices for PR70 specimens very high. If your 2004-S looks like a flawless mirror even under a magnifying glass, it might be worth sending in for professional grading.
Are There Any 2004-S Lincoln Penny Errors?
Error hunters are always on the lookout for doubled dies, off-center strikes, or “mule” errors. While no major, headline-grabbing errors have been widely reported for the 2,004-S Proof Penny specifically, minor anomalies do exist. These can include “die polish lines” or small “struck-through” errors where a piece of dust was caught between the die and the coin.
Most errors found in 2004 are actually on the Philadelphia (No Mint Mark) or Denver (D) strikes. For example, some 2004-D pennies show doubling on the ear of Lincoln or on the columns of the Lincoln Memorial. If you find a 2004-S that looks “fuzzy” or has double letters, you could be looking at a unique discovery coin.
Always inspect the “S” mint mark carefully. Occasionally, the mint mark itself can show doubling (RPM or Repunched Mint Mark), though this is much rarer in the modern era due to improved technology. Using a high-resolution app like CoinKnow is the best way to document and share these findings with the numismatic community.

How to Store and Protect Your 2004-S Penny
If you have a 2004-S Lincoln Penny, protection is key to maintaining its value. Because the coin is made of a zinc core with a thin copper plating, atmospheric moisture can cause tiny bubbles to form under the skin of the coin. This is often referred to as “plating blisters.”
For a Proof coin, you should never touch the surface with your bare fingers. The oils from your skin can leave permanent fingerprints that “eat” into the copper over time. Instead, handle the coin by its edges or use cotton gloves. Store the coin in a PVC-free plastic flip or a specialized coin capsule.
| Storage Method | Level of Protection |
|---|---|
| Original Mint Lens | Excellent |
| Plastic Coin Capsule (Air-Tite) | Maximum |
| Cardboard 2×2 Flip | Good (Budget) |
| Loose in a Jar | Poor (Avoid!) |
Investing in proper storage ensures that if you decide to sell your 2004-S Lincoln Penny in ten years, it will still retain its brilliant luster and satisfy the requirements of a high-end collector.
