The 1973 Lincoln Penny with no mint mark is worth anywhere from $0.01 in worn condition to over $1,500 for rare, high-grade specimens. While most of these coins found in pocket change are only worth their face value, certain copper compositions and high-quality strikes can be surprisingly valuable to collectors today.
| Condition / Grade | Estimated Value (USD) |
|---|---|
| Circulated (Average) | $0.01 – $0.05 |
| Uncirculated (MS63) | $0.15 – $0.50 |
| Choice Uncirculated (MS65 Red) | $1.00 – $10.00 |
| Gem Quality (MS67+) | $150 – $2,500+ |
History and Significance of the 1973 Lincoln Penny No Mint Mark
In 1973, the United States Mint produced billions of Lincoln Memorial pennies to satisfy the demands of American commerce. If you look at your penny and see no small letter “D” or “S” under the date, it means your coin was minted at the Philadelphia Mint. At the time, Philadelphia did not use a mint mark on pennies, a tradition that lasted for decades.
If you are just starting your journey into coin collecting, using the best coin identifier app can help you distinguish between a common Philladelphia strike and more valuable variations. In 1973, the Philadelphia Mint struck 3,728,245,000 pennies, making it one of the highest production years in history. Because of this massive supply, common circulated coins aren’t rare.
However, the “copper” value is something to keep in mind. Pennies minted before 1982, including the 1973 issue, are made of 95% copper and 5% zinc. Today, the raw metal value of these coins is often worth nearly 2 cents, though it is currently illegal to melt them down for profit.

Determining the 1973 Penny Value Based on Color
When evaluating a 1973 Lincoln Penny, professional graders categorize them into three main color categories: Red (RD), Red and Brown (RB), and Brown (BN). This classification significantly impacts the final price tag. CoinHix users often find that “Red” coins—those that retain at least 95% of their original copper mint luster—command the highest premiums.
Brown pennies are those that have oxidized over time due to exposure to air and skin oils. Most pennies you find in your spare change will be Brown. Red-Brown coins are the middle ground, showing some original luster but also significant toning. Because it is very difficult for a copper coin to stay “Red” for over 50 years, collectors pay a massive premium for those that have survived in pristine condition.
| Color Designation | Typical Grade | Price Range |
|---|---|---|
| Brown (BN) | VF20 – AU58 | $0.02 – $0.10 |
| Red-Brown (RB) | MS60 – MS64 | $0.20 – $2.00 |
| Red (RD) | MS65 – MS67 | $10.00 – $1,000+ |
Rare Errors and Varieties for the 1973 Penny
While most 1973 pennies are common, rare errors can turn a pocket change find into a windfall. Error hunting is a popular hobby among Americans who hope to find a “diamond in the rough.” Common errors to look for include Doubled Dies, Repunched Mint Marks (though not for the Philadelphia No Mint Mark version), and Off-Center strikes.
A Doubled Die Obverse (DDO) occurs when the hub strikes the die twice at slightly different angles. On a 1973 penny, you would look for doubling in the letters of “IN GOD WE TRUST” or “LIBERTY.” While no major, “famous” 1973 DDO is as well-known as the 1972 or 1955 versions, minor doubling is still collectible and can add $20 to $50 to the coin’s value.
Another exciting possibility is the “Off-Center” strike, where the coin was not properly aligned in the press. If a penny is 10% to 50% off-center and still shows the date “1973,” it can sell for $50 to $100. For anyone unsure if they have an error, using CoinHix to compare your coin against known error profiles is a great first step. Expert collectors often look at this detailed guide on 1973 penny value and rarity to identify specific die cracks or strike errors.
Grading Your 1973 No Mint Mark Penny
To understand why some 1973 pennies sell for hundreds of dollars while others are worth only one cent, you must understand grading. The Sheldon Scale, ranging from 1 to 70, is the industry standard. For a 1973 penny to be worth more than a few dollars, it generally needs to be in “Mint State” (MS60 or higher).
“About Uncirculated” (AU) coins show a tiny bit of wear on the highest points, such as Lincoln’s cheekbone or the pillars of the Memorial building. “Mint State” (MS) coins have no wear at all and still possess the “cartwheel” luster that reflects light in a rotating pattern. An MS67 1973 penny is extremely rare because the Philadelphia Mint in the 1970s was known for producing coins with many bag marks and scratches.
| Grade Group | Description | Value Multiplier |
|---|---|---|
| Good (G) – Fine (F) | Heavy wear, flattened details | Face Value |
| Extremely Fine (XF) | Sharp details, slight wear | 1x – 3x |
| Mint State (MS65+) | No wear, bright red color | 100x – 10,000x |
The Aluminum Penny Mystery of 1973
The year 1973 is famous in numismatic history because of a unique experiment. Due to rising copper prices, the U.S. Mint produced over 1.5 million pennies made of aluminum, dated 1974 but actually struck in late 1973. While these aren’t your typical “No Mint Mark” pennies found in change, they are the stuff of legends.
Most of these aluminum cents were recalled and destroyed, but a few were given to members of Congress and later went missing. If you ever find a 1973 or 1974 penny that is silver-colored and incredibly light, it could be an aluminum cent. However, be careful: many people coat normal pennies in mercury or zinc for science projects. A real aluminum penny will weigh only 0.93 grams, compared to the 3.11 grams of a standard 1973 copper penny. Using the CoinHix app can help you identify if the weight and metallic composition of your coin match official records.
Is it Worth Getting Your 1973 Penny Certified?
A common question for everyday Americans is whether they should send their 1973 penny to a grading service like PCGS or NGC. Professional grading typically costs $20 to $50 per coin plus shipping. Therefore, unless your 1973 penny is in flawless, bright red condition (looking like it just came off the press today), it usually isn’t worth the cost of certification.
Most 1973 pennies found in jars or old piggy banks will grade between “Very Good” and “About Uncirculated.” These are wonderful pieces of history but do not hold significant financial value. However, if you find a coin with a major error—like a deep double strike or a visible die capping error—certification can jumpstart its value by providing a guarantee of authenticity to potential buyers on eBay or at local coin shops.
| Auction Record Highlights | Grade | Price Sold |
|---|---|---|
| 1973 (Philadelphia) MS67 RD | MS67 Red | $3,800+ |
| 1973 (Philadelphia) MS66 RD | MS66 Red | $150 – $300 |
FAQ
Q: Why doesn’t my 1973 penny have a mint mark?
A: The absence of a mint mark means the coin was produced at the Philadelphia Mint. Until 1980 (and specifically for pennies), Philadelphia generally did not use a “P” mint mark. It is a completely normal occurrence for most pennies from this era.
Q: How can I tell if my 1973 penny is a rare error?
A: Look for anomalies like “doubled” letters or numbers, which indicate a doubled die. Check if the coin is off-center or has a strange color/weight. Most “errors” found by beginners are actually post-mint damage (scratches, chemicals, or being smashed), so compare your coin to known errors on educational sites.
Q: Is a 1973 penny made of real copper?
A: Yes, 1973 pennies are composed of 95% copper and 5% zinc. They are heavier (3.11g) and have a different “ring” when dropped compared to the zinc pennies (2.5g) produced after mid-1982.
Q: What is the most expensive 1973 penny ever sold?
A: High-grade specimens in MS67 Red condition have sold for over $3,000 at major auctions. These coins must be essentially perfect, with no scratches and full, bright orange-red luster from the day they were minted.
