The 1972-S Lincoln Penny is worth anywhere from $0.05 in circulated condition to over $1,000 for high-grade Deep Cameo proof specimens. While most found in pocket change are common, certain San Francisco mintages and rare errors hold significant value for collectors looking to complete their sets.
| Condition / Grade | Estimated Value |
|---|---|
| Circulated (Average) | $0.02 – $0.10 |
| Uncirculated (MS-63) | $1.00 – $3.00 |
| Proof (PR-67) | $5.00 – $15.00 |
| Deep Cameo (PR-69) | $40.00 – $150.00 |
Understanding the 1972-S Lincoln Penny History
If you have just found a “S” mint mark penny in your jar, you are holding a piece of San Francisco history. By 1972, the United States Mint was producing billions of one-cent pieces to keep up with the demands of commerce. The San Francisco Mint, however, played a specialized role during this era. While Philadelphia and Denver pumped out coins for circulation, the “S” mint mark often signified lower mintage numbers or specialized proof strikes intended for collectors.
Determining the exact variety of your coin is the first step toward a big payday. Many beginners struggle to tell the difference between a business strike intended for spending and a proof strike intended for an album. Using a top coin identifier app can help you zoom in on the mint mark and surface texture to see if your coin has the mirrored finish typical of San Francisco’s finest work.
The 1972-S is unique because it marks one of the final years that the San Francisco Mint produced pennies for general circulation. After 1974, the “S” mint mark primarily appeared only on proof sets. This makes any 1972-S found in a “wild” environment like a vending machine or tip jar a more interesting find than a standard 1972 Philly penny. If you aren’t sure what you have, the CoinKnow app can provide instant recognition.

Grading and 1972-S Lincoln Memorial Cent Values
In the world of coin collecting, condition is king. A 1972-S penny that has been rattling around in a piggy bank for fifty years will likely be “Circulated,” meaning it has scratches and lost its original luster. These are worth roughly their copper melt value (about 2 cents) or a small premium to a casual collector. However, if the coin looks brand new, it might be “Uncirculated” or “Mint State.”
Professional graders use a 70-point scale. For 1972-S business strikes, the jump in price from an MS-63 to an MS-67 is massive. You can view the current 1972-S penny auction trends and price data to see how much collectors are paying for these high-grade red specimens. Most business strikes were poorly handled, so finding a “Red” (RD) coin with no brown oxidation is the goal.
Proof coins, which were sold in sets, are graded using the “PR” prefix. These coins were struck twice on polished blanks. A 1972-S Proof penny is common, but one with a “Deep Cameo” (DCAM) effect—where Lincoln’s portrait looks like frosted white sugar against a black mirror background—is where the real money lies.

| Red (RD) | Original copper luster | $5.00 – $20.00 |
Identifying Rare 1972 Double Die Varieties
While the 1972-S is the star of the San Francisco mint that year, the most famous penny of 1972 is the Philadelphia Double Die Obverse (DDO). However, students of numismatics know that the San Francisco mint also had its share of “doubled dies,” though they are much rarer and often more subtle than the famous Philly version.
When checking your 1972-S, look closely at the words “IN GOD WE TRUST” and the date markers. If you see a clear secondary image or “doubling” of the letters, you may have found an error coin. These errors occur when the die used to strike the coin has a misaligned image on it. These are highly sought after by specialists and can push the price of a humble cent into the hundreds of dollars.

For a detailed breakdown of what to look for, you should check out the 1972 Lincoln penny value guide and error list. It provides high-resolution images of what genuine doubling looks like compared to “machine doubling,” which is a common manufacturing flaw that doesn’t add value. Using CoinKnow allows you to compare your coin against a database of known errors to see if yours matches.
The “S” Mint Mark: Proof vs. Business Strike
In 1972, the San Francisco mint produced about 376 million pennies for general circulation. This sounds like a lot, but compared to the 2.9 billion struck in Philadelphia, it’s a relatively low number. This makes the 1972-S business strike an “uncommon” find in modern change. Most of these coins have been pulled from circulation by collectors over the last 50 years.
The 1972-S Proof coins are a different story. About 3.2 million proof sets were sold by the U.S. Mint in 1972. While these were not intended for spending, many have been broken out of their plastic cases and spent by people who didn’t know their value. A “circulated proof” will look very shiny compared to a regular penny but will have lots of fine scratches (hairlines).

If you find a 1972-S that looks exceptionally shiny, even if it’s a bit scratched, keep it! It was likely part of a government-issued proof set. Identifying these differences is much easier if you download the CoinKnow app, which guides you through the visual markers of proof strikes versus business strikes.
| Mintage Type | Mintage Quantity | Rarity Score |
|---|---|---|
| 1972 (Phila) | 2,933,255,000 | Very Common |
| 1972-D (Denver) | 2,665,071,400 | Very Common |
| 1972-S (Business) | 376,939,108 | Common/Uncommon |
| 1972-S (Proof) | 3,260,996 | Collector Only |
What Makes a 1972-S Penny Especially Valuable?
Beyond the standard grades, there are “pedigreed” coins and specific color designations that drive prices up. For the 1972-S Lincoln Cent, the “Red” designation is essentially required for any coin to be worth more than a few dollars. Copper reacts with oxygen, turning from a bright orange-red to a dull brown. A 1972-S that has remained “Red” for 50 years is a rarity.
Another factor is the auction record. Sometimes, two collectors get into a bidding war over a specific coin that has been graded MS-67 or higher by the NGC or PCGS. These coins can sell for $500 to $1,200 depending on the day. For the average person, finding one of these in a coin jar is like winning a small lottery.
Finally, look for “Lamination Errors” or “Clipped Planchets.” While not as valuable as a major Double Die, these manufacturing mistakes are very popular. A lamination error looks like the skin of the coin is peeling off. If you find something that looks “wrong” with the metal itself, don’t clean it! Cleaning a coin actually destroys its numismatic value.

Summary: Should You Save Your 1972-S Pennies?
The short answer is yes. While a standard circulated 1972-S might only be worth 2 to 5 cents today, the price of copper alone makes it worth more than its face value. Currently, pennies struck before 1982 are 95% copper, and their metal content is worth roughly double the one-cent face value.
If you find an exceptionally clean, “Red” 1972-S, it is definitely worth setting aside in a protective flip or a small plastic bag. As the years go by, these S-mint mark coins become harder and harder to find in circulation. What is a 10-cent coin today might be a $5 coin in a decade as the supply of raw, unsearched 1970s coinage continues to dry up.
Before you spend it, use a coin app to ensure you aren’t missing a rare variety. Many 1972-S pennies look ordinary to the naked eye but reveal interesting die cracks or minting quirks under magnification. Keeping a small collection of these “S” cents is a great way to start a low-cost hobby that could eventually pay off.
FAQ
Q: Where is the mint mark on a 1972-S penny?
A: The “S” mint mark is located on the obverse (front) of the coin, directly below the date “1972.” If there is no letter there, the coin was minted in Philadelphia. If there is a “D,” it was minted in Denver.
Q: Is a 1972-S penny rare?
A: It is not “rare” in the sense that millions were made, but it is much less common than the Philadelphia or Denver versions. It is considered a “semi-key” date for casual collectors of the Lincoln Memorial series.

Q: How can I tell if my 1972-S is a proof?
A: Proof coins have a mirror-like background and very sharp, detailed strikes. Business strikes (for circulation) have a more “satin” or dull finish. If the background reflect light like a mirror, it’s a proof.
Q: Why is my 1972-S penny turning green?
A: This is called “environmental damage” or corrosion. Copper reacts with moisture and chemicals. Unfortunately, coins with green corrosion are generally only worth their face value or melt value, as collectors prefer clean coins.
Q: What is the highest price ever paid for a 1972-S penny?
A: While prices fluctuate, high-grade Deep Cameo proofs (PR-69 or PR-70) and MS-67 business strikes have been known to sell for over $1,000 at major heritage auctions.
