The 1955-S Wheat Penny is worth anywhere from $0.05 in worn condition to over $150 in high-grade mint state. Most examples found in pocket change today are worth a few cents, but certain “Red” gems can fetch a premium from serious collectors.

Why the 1955-S Wheat Penny Caught Your Eye

Finding an old Lincoln cent with a small “S” mint mark can be an exciting moment for any casual treasure hunter. If you’ve recently discovered one, you might be wondering if you’ve hit the jackpot. To quickly identify your coin and see what similar pieces are selling for, many collectors use a top coin identifier app to get instant results from their smartphone.

The 1955-S is a special coin because it represents the final year that the San Francisco Mint produced circulating pennies for over a decade. In 1955, the San Francisco Mint struck about 44.6 million pennies. While that sounds like a massive number, it is actually quite low compared to the hundreds of millions or even billions struck in Philadelphia and Denver that same year.

Because of this relatively lower mintage, people at the time realized these coins might be rare. Many bags were stashed away under beds and in safes, meaning plenty of 1955-S pennies survived in beautiful, shiny condition. If your coin looks brand new, you should definitely check it with CoinKnow to see if it carries a “Red” designation, which significantly boosts the price.

Understanding the 1955-S Lincoln Cent Mint Mark

The “S” on your penny stands for San Francisco. During the mid-1950s, the San Francisco Mint was winding down its production of minor coins. In fact, after 1955, they stopped making pennies for circulation entirely until 1968. This “sunset” of San Francisco production makes the 1955-S a favorite for people completing a Wheat Penny album.

The mint mark is located just below the date “1955” on the obverse (heads) side of the coin. If the area below the date is blank, it was made in Philadelphia. If there is a “D”, it was made in Denver. Generally, the 1955-S is more desirable than the 1955-D or the plain 1955, unless you happen to find the famous “Doubled Die” variety from Philadelphia.

When examining your coin, look for the clarity of the “S.” Sometimes the mint mark can appear “filled” or “blob-like” due to old, worn-out dies. While interesting, these minor mint errors usually don’t add massive value, but they are great conversation pieces for your collection.

Grading and Condition: Why Color Matters

For a copper coin like the 1955-S, the value is determined by two main factors: how much it has been used (Grade) and its color. Copper reacts with oxygen over time, turning from a bright orange-red to a dark chocolate brown. Professionals categorize these as Red (RD), Red-Brown (RB), or Brown (BN).

Color Designation	Description	Price Impact
Red (RD)	95% original mint luster remains.	Highest value; most sought after.
Red-Brown (RB)	Mix of original copper and brown patina.	Moderate value.
Brown (BN)	Almost entirely dark copper/brown color.	Standard value for circulated coins.

For those looking for high-end market data, the 1955-S Wheat Penny MS67 RD price can reach several hundred dollars at auction. Most coins found in change will be “Brown” and in the “Good” to “Extremely Fine” range, making them worth a few cents to a quarter.

The “BIE” Error and Other 1955-S Varieties

The 1955-S is famous among error collectors for the “BIE” error. This is a small vertical die crack that occurs between the letters “B” and “E” in the word “LIBERTY.” It looks like a small capital “I” is standing between the letters, making it look like “LIBIERTY.”

While this is technically a die break and not a “rare” error in the sense of making you a millionaire, it is a highly collectible variety. Many people use CoinKnow to identify these small nuances that the naked eye might miss. A 1955-S with a clear BIE error might sell for $5 to $15 to a specialist, which is a huge percentage increase over a normal penny!

Other minor issues to look for include “clashed dies” or “die chips.” Because the San Francisco Mint was using their equipment until it practically fell apart in 1955, many coins show signs of die fatigue. While these don’t always add value, they make your specific coin unique in the world of numismatics.

Current Market Value and Pricing Trends

The market for Wheat Pennies remains strong because they are the “entry point” for many new hobbyists. Unlike gold or silver coins, you can still find a 1955-S for a very affordable price. However, as more people get into the hobby, the demand for high-grade, certified examples continues to rise.

According to recent sales data, you can find a comprehensive 1955 penny value chart that compares the S-mint to the Philadelphia and Denver issues. Generally, the San Francisco version holds a slight edge in value over the Denver version in lower grades, simply because fewer were made.

If you have a roll of these coins, it is worth looking through them for one that still has that original “wet paint” luster. A single coin in MS66 or MS67 grade is worth more than five hundred “regular” circulated pennies combined.

Grade (PCGS/NGC)	1955-P (Plain)	1955-D	1955-S
MS63 Red	$5	$4	$6
MS65 Red	$15	$12	$18
MS67 Red	$500+	$100	$150

Tips for Selling Your 1955-S Wheat Penny

If you’ve decided it’s time to part with your coin, don’t just take it to a generic “We Buy Gold” shop. These businesses often pay only the “melt value” or a flat rate for bulk pennies. Instead, check the current trends on CoinKnow to see what private collectors are currently paying on auction sites like eBay or Heritage Auctions.

For individual coins worth less than $10, your best bet is usually a local coin shop or selling it as part of a “Lincoln Cent Folder” set. If you believe your 1955-S is in truly exceptional, “Red” condition, you might consider having it professionally graded by PCGS or NGC, though this costs money and is only worth it for high-value coins.

Always remember: never clean your coins! Even a gentle rub with a cloth can leave tiny scratches that professional graders will see instantly. A cleaned coin can lose 50-80% of its collector value. Keep it in its original state to ensure you get the best possible price when it comes time to sell.
