The 1915-S Wheat Penny is worth anywhere from $20 in worn condition to over $1,200 in pristine mint state. While not the rarest coin in the Lincoln Cent series, the San Francisco mint mark makes it a highly desirable piece for collectors looking to complete their early 20th-century sets.
| Condition / Grade | Estimated Value |
|---|---|
| Good (G-4) | $20 – $25 |
| Fine (F-12) | $35 – $45 |
| Extremely Fine (XF-40) | $75 – $95 |
| Uncirculated (MS-63) | $250 – $400 |
| Mint State Red (MS-65 RD) | $1,100 – $3,000+ |
Why the 1915-S Wheat Penny Status Matters
If you’ve found a penny dated 1915 with a tiny “S” underneath the date, you have found one of the lower-mintage years for the early Lincoln Wheat Cent series. In 1915, the San Francisco Mint produced only about 4.8 million coins. Compared to the hundreds of millions produced in modern years, this is a tiny number that keeps demand high.
Because these coins were released into general circulation over a century ago, most surviving examples are heavily worn or damaged. Finding a high-quality survivor can be difficult, which is why accurate identification is key. Using the best coin identifier app can help you confirm the mint mark and distinguish between common dirt and valuable patina.
For everyday Americans, the 1915-S is often a “hidden treasure” in old jars or inherited collections. Collectors value the “S” mint mark because San Francisco generally had lower production runs than Philadelphia (which has no mint mark).

Grading and 1915-S Lincoln Cent Price Factors
The value of your 1915-S penny is primarily determined by its grade. Grading is a scale from 1 to 70 used by professionals to describe a coin’s condition. In the world of Wheat Pennies, even a small difference in detail can mean a difference of hundreds of dollars in market price.
A “Good” grade means the coin has seen heavy use; the lines of the wheat stalks on the back are likely worn smooth, and Lincoln’s bust is just an outline. As you move up to “Extremely Fine,” you should see distinct lines in Lincoln’s hair and sharp “Wheat” ears. The most valuable coins are “Red” (RD), meaning they still have the original copper glow from the day they were minted.
Understanding the 1915-S Wheat Penny Mint State red auction results is essential for anyone who thinks they have a high-grade specimen. These coins are exceptionally rare because copper naturally oxidizes and turns brown over time.
| Color Designation | Visual Description | Price Impact |
|---|---|---|
| Brown (BN) | Dark chocolate color, no luster left. | Standard market value. |
| Red-Brown (RB) | At least 5% to 95% original orange color. | Moderate premium. |
| Red (RD) | Over 95% original orange-red copper luster. | Significantly high premium. |
1915-S vs. 1915-P and 1915-D Pennies
In 1915, three mints produced Wheat Pennies: Philadelphia (no mint mark), Denver (D), and San Francisco (S). While the Philadelphia mint produced nearly 30 million coins, the San Francisco mint only produced about 16% of that amount. This disparity is why the 1915-S is usually the “key” coin for that specific year.
If you find a 1915 penny without a mint mark, it is likely worth only $1 to $5 in average used condition. However, the presence of that small “S” instantly boosts the floor price to around $20. For those looking for precise 1915 Lincoln cent value and mintage data, it’s clear that the San Francisco version is the king of the 1915 production.
If you’re unsure if you’re looking at a “D” or an “S,” CoinHix can assist with its high-resolution magnification features. Sometimes a dirty “D” can look like an “S,” and knowing the difference is vital before you try to sell it to a coin shop.
How to Spot a Fake 1915-S Wheat Penny
Because the 1915-S is valuable, counterfeiters sometimes try to add an “S” mint mark to a common 1915 Philadelphia penny. This is known as an “added mint mark.” To the untrained eye, it looks legitimate, but under a microscope, you can often see a seam or glue around the letter.
Another common issue is “cleaned” coins. Many people think they are helping by scrubbing an old penny to make it shine. In the coin world, this actually destroys the value. A cleaned 1915-S might lose 50% or more of its potential market price because the original surface has been scratched and altered.
Always handle your coins by the edges. Even the oils from your fingers can cause degradation over time. If you suspect you have a high-value version, placing it in a PVC-free plastic holder is the best way to preserve its current state. Using a tool like CoinHix to catalog your find digitally ensures you have a record of its condition before any further handling.
| Checklist Feature | What to Look For |
|---|---|
| Mint Mark Location | Below the date “1915”. |
| Luster | Does it spin when rotated in light (original) or is it dull (cleaned)? |
| Wheat Ears | Are the parallel lines at the top of the stalks visible? |
Selling Your 1915-S Wheat Penny
Once you’ve identified your coin and estimated its grade, the next step is realizing that value. Selling to a local coin shop is the fastest way to get cash, but keep in mind that dealers need to make a profit, so they may offer you 60-70% of the retail value.
For top-tier specimens in Mint State, auction houses like Heritage Auctions or Stack’s Bowers are often the best route. For mid-grade coins, online marketplaces like eBay are popular, but you must take clear, high-quality photos. Buyers want to see the “S” clearly and check for any hidden scratches.
Before selling, check the latest “sold” listings rather than “asking” prices. Anyone can ask for $1,000 for a penny, but that doesn’t mean it will sell. Reliable data is your best friend when negotiating a fair price for your piece of American history.
FAQ
Q: Where is the mint mark on a 1915-S Wheat Penny?
A: The “S” mint mark is located on the obverse (front) of the coin, directly underneath the date “1915.” If there is no letter there, the coin was minted in Philadelphia.
Q: Is the 1915-S penny made of real copper?
A: Yes, the 1915-S Lincoln Cent is composed of 95% copper and 5% tin and zinc. It weighs approximately 3.11 grams, which is heavier than the modern zinc pennies made today.
Q: Should I clean my 1915-S penny to make it worth more?
A: No! Never clean your coins. Professional collectors prefer “original skin,” which is the natural toning that happens over a century. Cleaning creates microscopic scratches that significantly lower the coin’s grade and value.
Q: Is a 1915-S penny rare?
A: It is considered a “semi-key” date. With only 4,833,000 minted, it is much scarcer than common Wheat Pennies, though not as rare as the 1909-S VDB or the 1914-D.
