History and Significance of the 1928-S Lincoln Wheat Cent
If you’ve recently discovered an old copper coin in a jar or an inherited collection, you might be holding a piece of American history from the Roaring Twenties. To accurately identify your find, many hobbyists use a top coin identifier app to distinguish between different mint marks and dates. The 1928-S Wheat Penny was struck at the San Francisco Mint during a year of high economic activity, just before the Great Depression began.
With a mintage of 17,266,000, the 1928-S is considered a semi-key date in the Lincoln Cent series. While seventeen million might sound like a lot, it is significantly lower than the outputs from Philadelphia that year. Because fewer were made and even fewer were saved in pristine condition, collectors are often willing to pay a premium for this specific San Francisco issue.
Using the CoinKnow app can help you determine if your coin features the sharp “S” mint mark located right under the date. This small letter makes a massive difference in value compared to coins without a mint mark. Identifying the luster and surface quality is the first step toward figuring out if your penny is a common circular find or a valuable treasure.

Determining the 1928-S Wheat Penny Value by Grade
The condition, or “grade,” of your coin is the most important factor in its market price. Most 1928-S pennies found today are in “Good” or “Fine” condition, meaning they have significant wear on Lincoln’s hair and the wheat stalks on the reverse. For these common grades, the price usually hovers between $1 and $5.

However, once you move into “About Uncirculated” or “Mint State” categories, the value jumps significantly. Collectors look for “Full Red” (RD) color, which indicates the coin has retained its original copper glow from the day it was minted. For detailed pricing on these high-end versions, check the 1928-S Wheat Penny price guide for Red specimens to see how color affects the bottom line.

| MS-60 (Uncirculated) | $35 – $45 | $55 – $70 |

Key Identifying Features and Variations
When examining your 1928-S Wheat Penny, you should look closely at the “S” mint mark. During this era, mint marks were hand-punched into the dies, leading to slight variations in position and clarity. Some collectors hunt for “Large S” or “Small S” varieties, though the 1928-S doesn’t have the famous variety distinctions of the 1928-D.
To truly understand what you have, check the current 1928 penny market value trends to see how the San Francisco mint compares to the Philadelphia and Denver issues. You will notice that the “S” mint mark usually carries the highest premium for that year because San Francisco had the lowest production numbers.
The CoinKnow app is particularly useful here for its high-resolution image comparison tools. By comparing your coin to known graded examples, you can spot “Woody” toning (rolling lines in the metal) or planchet flaws that might make your coin unique. Even if your coin isn’t a top-tier grade, these unique characteristics can sometimes attract a specific niche of buyer.

Rare Errors and Varieties to Look For
While the 1928-S isn’t as famous for errors as the 1955 Doubled Die, there are still several things to keep an eye out for. These include “off-center strikes,” where the image isn’t perfectly centered on the copper planchet, and “die cracks,” which look like raised lines running through the design.
One of the most valuable occurrences is a “re-punched mint mark” (RPM). This happens when the person punching the “S” into the die hit it twice, creating a shadowed or doubled effect on the letter. Such errors can double or triple the value of the coin compared to a standard strike of the same grade.
| Error Type | Estimated Added Value |
|---|---|
| 10% Off-Center Strike | $20 – $50 |
| Lamination Error | $5 – $15 |
| Die Crack (Major) | $10 – $30 |
How Color Affects the Value of Copper Coins
Copper is a unique metal because it reacts with oxygen over time. For the 1928-S Wheat Penny, professional graders categorize the color into three buckets: Red (RD), Red-Brown (RB), and Brown (BN). A “Red” coin looks exactly as it did when it left the mint, while a “Brown” coin has developed a dark patina from circulation.

The price difference between these colors is staggering. For instance, a 1928-S in MS-65 condition might sell for $300 if it is Brown, but it could fetch $2,000 or more if it is designated as Full Red. This is because copper naturally turns brown over 90 years, making “Red” survivors incredibly rare.
If you aren’t sure which color category your penny falls into, CoinKnow provides side-by-side color charts. Most coins found in everyday settings will be “Brown.” If you find one that still looks bright and shiny, do not clean it! Cleaning a coin actually destroys its numismatic value. Keep it in a soft flip or a plastic container to preserve what remains of its original finish.
FAQ
Q: Why is the “S” mint mark so important on a 1928 penny?
A: In 1928, the San Francisco Mint produced significantly fewer pennies than the Philadelphia Mint. Because of this lower supply, the “S” versions are rarer and more desirable to collectors than those with no mint mark.

Q: Can I find a 1928-S Wheat Penny in my pocket change today?
A: While it is extremely rare, it is still possible to find Wheat Pennies in circulation. However, most 1928-S pennies have been pulled from circulation by collectors over the last 90 years. You are more likely to find them in estate sales or old coin jars.
Q: Does cleaning my 1928-S penny increase its value?
A: No! Never clean your coins. Collectors prefer the natural patina and aging of the copper. Chemical cleaners or abrasive cloths will leave microscopic scratches that drastically reduce the coin’s professional grade and market value.
Q: What is the most expensive 1928-S Wheat Penny ever sold?
A: A 1928-S Lincoln Cent graded MS-66 Red once sold at auction for over $7,000. These high prices are reserved for coins that are virtually perfect with no visible scratches or spots under magnification.
