The 1966 Lincoln Penny is worth anywhere from $0.01 in worn condition to over $1,500 for rare high-grade specimens. While most of these pennies found in pocket change are only worth their weight in copper, certain errors and pristine conditions can make them quite valuable to serious collectors today.
| Condition / Grade | Estimated Value |
|---|---|
| Circulated (Average Wear) | $0.01 – $0.05 |
| Uncirculated (MS63 Red) | $1.00 – $5.00 |
| Gem Quality (MS66 Red) | $25.00 – $50.00 |
| Superb Gem (MS67+ Red) | $500 – $1,500+ |
Understanding the 1966 Penny With No Mint Mark
If you are looking at a 1966 penny and notice there is no small letter (mint mark) under the date, you aren’t looking at an error. In fact, between 1965 and 1967, the United States Mint removed all mint marks from coins to discourage coin collecting during a national coin shortage. During this period, all pennies were struck at the Philadelphia, Denver, and San Francisco mints, but they all looked identical. Using a top coin identifier app can help you distinguish the subtle luster and strike quality of these “Special Mint Set” years.
Because billions of these coins were produced, they are incredibly common. Most Americans have likely had dozens of these pass through their hands without realizing it. However, because they are made of 95% copper, they actually have an intrinsic melt value that is higher than their face value. While it is currently illegal to melt pennies for profit, many people hoard these 1966 issues for their metal content. To get a precise reading on your specific coin, the CoinKnow app offers an easy way to scan and catalog your discovery.
When evaluating these coins, the most important factor is the color. Copper coins are graded as Red (RD), Red-Brown (RB), or Brown (BN). A “Red” 1966 penny is one that has retained its original mint luster and hasn’t oxidized. These are the coins that collectors are willing to pay a premium for. If your coin looks like a shiny new penny despite being decades old, it might be worth more than a few cents.

Determining the 1966 Lincoln Penny Value by Grade
The value of a 1966 Lincoln Memorial Penny scales dramatically based on its condition. Most coins found in jars or parking lots will be “Circulated,” meaning they have scratches and dullness from being used in commerce. These are generally only worth face value. However, “Uncirculated” coins—those that never made it into a cash register—begin to climb in price. Professional grading services like PCGS or NGC use a 70-point scale to determine exact worth.

High-grade specimens are the “Holy Grail” for Lincoln Cent enthusiasts. For example, a 1966 penny in MS67 (Mint State 67) condition is a rare find because the large production numbers often led to bags of coins clashing together, creating “bag marks” or nicks. According to recent auction data, the 1966 Penny MS RD price guide suggests that top-tier specimens can reach several hundred dollars if the strike is sharp and the surface is flawless.

Rare 1966 Penny Errors to Look For
While standard pennies are common, error coins are the exceptions that can turn a “pocket change” find into a major payday. One of the most sought-after errors for this year is the Doubled Die Reverse (DDR). This happens when the die used to strike the coin has a misaligned image, causing letters like “E PLURIBUS UNUM” or “UNITED STATES OF AMERICA” to appear doubled. Identifying these requires a magnifying glass or a high-quality camera zoom.
Other common errors include “Off-Center Strikes,” where the coin was not perfectly aligned in the press, leaving a crescent moon shape of blank copper on one side. There are also “Clipping Errors,” where the circular planchet was cut improperly before striking. If you suspect you have an error, CoinKnow can help you compare your coin against known error databases to see if you have a winner. Many of these errors can sell for $50 to $200 depending on the severity of the mistake.
Don’t ignore the “SMS” or Special Mint Set coins from 1966 either. These weren’t intended for circulation but sometimes find their way there. They have a satin-like finish and a much sharper strike than standard pennies. If your 1966 penny looks exceptionally detailed—almost like a proof coin—it might be an SMS strike. Check out this 1966 penny value and rarity chart to see how these special strikes differ in price from regular business strikes.

Is a 1966 Penny Made of Silver or Rare Metals?
A common misconception among new collectors is that some 1966 pennies might be rare because they are “silver” in color. If you find a silver-colored 1966 penny, it is almost certainly a victim of “post-mint damage” or a science experiment. In the 1960s, it was popular for chemistry students to “plate” pennies in zinc or mercury, giving them a silver sheen. These altered coins have no extra value and are actually considered damaged by collectors.
The only way a 1966 penny would be legitimately silver-colored from the mint is if it was accidentally struck on a dime planchet. This is a rare and valuable error. To check this, weigh your coin. A standard 1966 penny should weigh 3.11 grams. If it weighs significantly less (around 2.27 grams) and has a smaller diameter or a reeded edge like a dime, you may have found a genuine “wrong planchet” error worth thousands of dollars.
For the average person holding a brown, worn 1966 penny, the value remains tied to its copper content. Since copper prices fluctuate, the metal value is usually around 2 to 3 cents. While not enough to retire on, it is still double or triple the face value of the coin! If you are sorting through “wheat pennies” and “memorial pennies,” using an app like CoinKnow can help you quickly separate the common copper cents from the potentially valuable errors.

Where to Sell Your 1966 Lincoln Memorial Penny
If you believe you have found a high-grade or error 1966 penny, the next step is knowing where to sell it. For average uncirculated coins worth $5 to $20, eBay is often the best platform. You can take clear, high-resolution photos and list the coin for auction. Make sure to capture the date and the reverse side clearly so buyers can see the lack of wear.
For coins that appear to be in “Gem” condition or have a clear doubled die error, it is worth consulting a local coin shop or a professional grading service like PCGS. Professional grading costs money, so you should only do this if the coin’s value justifies the $20-$50 grading fee. Often, a quick consultation with a dealer can tell you if your coin is a candidate for professional certification.
| Selling Method | Best For… | Estimated Fees |
|---|---|---|
| eBay | Low to Mid-range coins | 13% + Shipping |
| Local Coin Shop | Quick cash / expert opinion | Varies (Buy prices lower than retail) |
| Heritage Auctions | High-value errors ($500+) | 15-20% Commission |
FAQ
Q: Why doesn’t my 1966 penny have a mint mark?
A: In 1966, the US Mint deliberately removed mint marks from all coins to discourage people from hoarding coins during a nationwide shortage. It is not an error; it simply means the coin could have been minted in Philadelphia, Denver, or San Francisco.

Q: How much copper is in a 1966 penny?
A: A 1966 penny is composed of 95% copper and 5% zinc. This is why they are heavier (3.11g) than modern pennies made after 1982, which are mostly zinc and weigh only 2.5 grams.
Q: Is there a 1966 “D” or “S” penny?
A: No. While the Denver and San Francisco mints did strike pennies in 1966, they were required by law not to include their “D” or “S” mint marks. Every legitimate 1966 penny will appear to have “no mint mark.”
Q: What is the most expensive 1966 penny ever sold?
A: The record price for a 1966 Lincoln Penny is over $2,800 for a specimen graded MS67+ Red by PCGS. These are exceptionally rare because copper coins tend to spot or discolor over time.
