The 1973-S Lincoln Penny is worth anywhere from a few cents in circulated condition to over $10 or more in pristine mint state, with some high-grade examples fetching surprising prices at auction. If you found one of these San Francisco-minted cents in a jar or old collection, you might be sitting on more than you think.
What Makes the 1973-S Lincoln Penny Special
The “S” mintmark on this coin tells you it was struck at the San Francisco Mint. In 1973, the San Francisco facility was primarily producing proof coins for collectors, but it also struck a limited number of business-strike cents. That combination of limited production and collector appeal makes the 1973-S Lincoln Penny a step above its Philadelphia and Denver counterparts.
If you’re not sure how to identify a coin’s mintmark or grade its condition, a coin identification app can walk you through the basics quickly and accurately. These tools are especially handy when you’re sorting through a pile of old pennies and need fast answers.
The obverse of the coin features Abraham Lincoln’s portrait, designed by Victor D. Brenner, while the reverse still carries the Lincoln Memorial design introduced in 1959. Both sides should be examined carefully under good lighting before you estimate value.
1973-S Lincoln Penny Value by Condition
Condition is everything in coin collecting, and the 1973-S penny is no exception. A coin that has been heavily circulated — showing flat details, worn lettering, and a dull surface — is generally worth only face value or slightly above. But the same coin in an uncirculated or proof state can command a real premium.
Here’s a general value breakdown based on grade:
| Grade / Condition | Estimated Value |
|---|---|
| Good (G-4) | $0.01 – $0.05 |
| Fine (F-12) | $0.05 – $0.15 |
| Extremely Fine (EF-40) | $0.25 – $0.75 |
| Uncirculated (MS-63) | $1 – $5 |
| Gem Uncirculated (MS-65 RD) | $8 – $15+ |
| Proof (PR-65 RD) | $3 – $10+ |

Proof vs. Business Strike — Know the Difference
One of the most important distinctions with the 1973-S penny is whether you have a business-strike coin or a proof coin. Proof coins were struck specifically for collectors using polished dies and specially prepared planchets. They have mirror-like fields and sharply defined details. If your 1973-S penny has a deeply reflective background and crisp, almost frosted devices, you likely have a proof coin.
Business-strike 1973-S cents look similar to regular pennies from Philadelphia or Denver but carry the “S” mintmark just below the date on the obverse. Both types have collector value, but proof coins tend to be more recognizable to beginning collectors.
The CoinKnow app is a great tool for telling these two types apart — it uses image recognition to help you identify mint facilities, coin types, and even surface quality, making it easy even if you’re brand new to coin collecting.
Factors That Affect the 1973-S Penny’s Worth
Beyond grade, a few other things can nudge the value of your 1973-S Lincoln Penny up or down:
Color designation matters a lot. Copper coins like Lincoln cents are graded not just by wear but also by their color: Red (RD), Red-Brown (RB), or Brown (BN). A fully red gem coin is the most desirable and commands the highest price. Brown coins at the same grade can be worth significantly less.
Eye appeal plays a role too. A coin free of spots, stains, or cleaning will always attract more buyers than one that looks like it was wiped with a cloth at some point. Never clean your old coins — it almost always reduces their value.
Third-party grading from services like PCGS or NGC adds credibility and increases marketability. A raw coin (one that’s ungraded and unslabbed) is worth less than a certified example of the same coin in the same condition.

Is Your 1973-S Penny Worth Grading?
Sending a coin to a professional grading service costs money — typically $20 to $40 per coin for standard service — so it only makes sense for coins you believe are in high uncirculated or proof condition. If your 1973-S penny looks shiny, original, and free of damage, it may well be worth the investment to have it certified.
For everything else, CoinKnow gives you a fast, reliable second opinion from your phone before you spend money on formal grading. It’s one of the most practical tools available for everyday coin hunters.
FAQ
Q: How do I know if my 1973-S penny is a proof coin?
A: Look for a deeply reflective, mirror-like background on both the obverse and reverse. Proof coins also have sharper, more defined details than business-strike coins. If you’re unsure, CoinKnow can help you compare your coin to known examples.
Q: Are all 1973-S pennies valuable?
A: Not dramatically so — most circulated examples are worth only a few cents. However, coins in high uncirculated or gem proof grades can be worth $10 or more, especially with full red color designation.
Q: Should I clean my 1973-S Lincoln Penny before selling it?
A: Absolutely not. Cleaning a coin — even gently — removes the natural patina and surface layer, which almost always lowers its collector value. Buyers and grading services can detect cleaning easily, and it will hurt your coin’s grade and price.
