History and Significance of the 1928 San Francisco Penny
Produced during an era of economic prosperity, the 1928-S Lincoln Wheat Cent is a favorite among numismatists. While the Philadelphia mint struck over 134 million pennies that year, the San Francisco mint (identified by the “S” mint mark) produced a much lower volume. If you aren’t sure how to identify your coin, using a free coin identifier app can help you confirm the minting location and date within seconds.
The San Francisco mint was known for sometimes having “mushy” strikes during this period. Because of this, finding a 1928-S with sharp, crisp details is quite a challenge. Most of the pennies you will find in jars or old collections have been circulated heavily, losing their original luster and high-relief features.
For a modern collector, the CoinKnow app provides an excellent way to track the rarity of these west-coast beauties. Whether the coin is a Brown (BN), Red-Brown (RB), or Red (RD) variety significantly impacts the market price. The specialized 1928-S Wheat Penny price guide for Red specimens shows that the brightest coins fetch the highest premiums at auction.
How to Grade Your 1928-S Wheat Penny
Grading is the most critical factor in determining how much your coin is worth. To the untrained eye, two pennies might look similar, but a single grade point difference can mean hundreds of dollars. Professional graders look at the wear on Lincoln’s cheekbone, the “IT” in “LIBERTY,” and the clarity of the wheat stalks on the reverse.
In “Good” condition, the coin will be heavily worn. The outlines of Lincoln and the wheat ears are visible, but the finer details are gone. By the time a coin reaches “Extremely Fine,” most of the hair lines and the lines in the wheat ears are sharp. “Mint State” coins have no wear at all and still possess the original copper glow from the day they were struck.
For many everyday Americans, trying to distinguish between EF-40 and AU-50 is frustrating. Using a tool like CoinKnow allows you to compare your coin’s photo against a database of graded examples. This helps you get a realistic idea of the 1928 Wheat Penny value based on current market trends before you visit a coin shop.
| Grade Definition | Visual Indicators |
|---|---|
| Good (G-4) | Main features are flat; date and mint mark are legible. |
| Fine (F-12) | Some separation in Lincoln’s hair; wheat lines are mostly clear. |
| About Uncirculated (AU-50) | Only slight wear on the highest points; looks nearly new. |
| Mint State (MS-63) | No wear; original luster present, though some marks may exist. |
The Importance of Copper Color (BN, RB, RD)
Copper coins are unique because their color changes over time as they react with oxygen. The 1928-S penny is categorized into three color grades: Brown (BN), Red-Brown (RB), and Red (RD). Collectors prize “Red” coins most because they look exactly as they did in 1928.
A Brown 1928-S is the most common for circulated coins. These have turned a chocolatey or dark brown hue. Red-Brown coins have a mixture of both original orange-red and brown oxidation. True “Red” coins are rare for the San Francisco mint from this year, as many coins were released into circulation immediately or stored in poor conditions.
If you happen to find a 1928-S that still looks bright orange or red, do not clean it! Cleaning a coin destroys its numismatic value. Instead, use CoinKnow to see how much of a premium a “Red” designation adds to your specific 1928-S Wheat Penny.
| Color Class | Typical Price (MS-63) | Availability |
|---|---|---|
| Brown (BN) | $55 – $70 | Common |
| Red-Brown (RB) | $80 – $110 | Scarce |
| Red (RD) | $250 – $450 | Very Rare |
Valuable Errors and Varieties for the 1928-S Penny
While the standard 1928-S is worth a decent amount, error hunters look for specific anomalies that can skyrocket the value. One of the most sought-after varieties for this year involves the mint mark itself. Some 1928-S pennies feature a “Large S” or “Small S” mint mark, though the distinction is often subtle.
Other errors to look for include Repunched Mint Marks (RPM), where the “S” appears doubled or shifted. Die cracks, where a thin line of raised metal appears across the coin’s surface, are also common but usually only add a small premium. Off-center strikes are much more valuable, where the image was not centered on the copper planchet.
If you find a penny that looks “weird” or has extra lines or letters, keep it separate from your other coins. Many of these errors are sold for $20 to $100 even in lower grades. Using a magnifying glass or a high-resolution phone camera is the best way to spot these hidden treasures.
Comparing the 1928-S to Philadelphia and Denver Mints
To truly understand the value of your 1928-S, it helps to see how it stacks up against its cousins from Philadelphia (no mint mark) and Denver (D mint mark). In 1928, the Philadelphia mint produced the most coins, making them generally the least valuable today. The Denver mint produced about 31 million, while San Francisco produced approximately 17 million.
Because the 1928-S has the lowest mintage of the three, it typically carries a higher price tag in almost every grade. While a 1928 Philadelphia penny might only be worth a few cents in worn condition, a 1928-S will almost always be worth a premium over its face value.
| Mint Mark | Mintage Quantity | Avg. Value (Fine) |
|---|---|---|
| None (Philly) | 134,116,000 | $0.15 |
| D (Denver) | 31,170,000 | $0.75 |
| S (San Francisco) | 17,266,000 | $2.00 |
Where to Sell Your 1928-S Wheat Penny
If you’ve discovered that you own a high-grade 1928-S, you might be wondering how to turn it into cash. For lower-grade, circulated coins, your local coin shop or an eBay listing is usually the best bet. These venues are great for selling coins worth $1 to $20.
For high-value coins (those worth over $100), you should consider having the coin professionally graded by services like PCGS or NGC. This “slabbing” process authenticates the coin and locks in its grade, making it much easier to sell to serious collectors at auction houses like Heritage Auctions or GreatCollections.
Always remember to research recent “Sold” listings rather than “Asking” prices. Anyone can ask $1,000 for a penny, but what matters is what people are actually paying. Keeping an eye on auction results will ensure you get a fair price for your piece of 1920s history.
FAQs
Q: Where is the mint mark on a 1928-S Wheat Penny?
A: The “S” mint mark is located on the obverse (front) of the coin, directly underneath the date “1928.” If there is no letter below the date, it was minted in Philadelphia.
Q: Is the 1928-S Wheat Penny rare?
A: It is not “rare” in a general sense, as millions were made. However, it is considered “semi-key” in high uncirculated grades (MS-65 and above) and is much harder to find in those conditions than the Philadelphia version.
Q: Should I clean my old 1928-S penny to make it look newer?
A: No! Never clean your coins. Cleaning causes microscopic scratches and removes the natural patina, which can reduce a coin’s value by 50% or more. Collectors prefer coins with natural aging.
Q: What is the most expensive 1928-S penny ever sold?
A: High-grade specimens in MS-66 Red condition have sold for over $10,000 at major auctions. These are exceptionally rare and possess perfect surfaces and brilliant original color.
