What does a double-die penny look like? Looking closely at the details on a penny can reveal treasures like the elusive double-die penny. If you have ever wondered what a double-die penny looks like and how to identify one, you’ve come to the right place.
If you’re short on time, here’s a quick answer to your question: A double die penny has a dramatic doubling of design elements like words, numbers, or images caused by an error during the minting process. Under a magnifying glass, the doubling is very apparent compared to a normal penny.
In this comprehensive guide, we will cover everything you need to know about double-die pennies including what causes them, key dates and valuations, how to spot them, and tips for collecting your own.
What Causes a Double Die Penny?
The Minting Process for Pennies
Pennies are produced at very high speeds – up to 13,000 coins per minute! This rapid pace leaves room for errors to occur. Here’s an overview of how pennies are made:
- Blank metal coin blanks are fed into presses containing engraved dies
- Tremendous pressure is applied to stamp the coin design onto the blanks
- Coins are ejected and inspected for defects
- Acceptable coins are counted and bagged for distribution
With so many pennies flooding through the minting presses each minute, even tiny misalignments of the dies can lead to a doubling of design elements on some coins.
How Double Dies Happen
Double dies occur when the die containing the design hub shifts slightly during the stamping process. This results in a secondary, overlapping impression. Areas most prone to exhibit doubling are letters, numbers, and the coin’s date.
Double dies fall into two categories:
- Class I: The die moves significantly between impressions, resulting in clear, separated doubling of design elements.
- Class II: The die only shifts slightly, leading to minor secondary impressions very close to the primary design.
Class II doubled dies are more common as the die doesn’t have to move much to create slight doubling. But Class I is more dramatic and thus collectible.
Editor’s note: A fun fact is that only around 20,000-30,000 double-die Lincoln cents enter circulation each year, making them scarce!
Key Double Die Pennies and Valuations
1955 Double Die Obverse Penny
The 1955 double-die obverse penny is one of the most famous error coins in U.S. history. This coin features doubling in the date and lettering on the obverse (front) side due to misaligned die hubs during the minting process at the Philadelphia Mint.
Only around 20,000 to 24,000 of these coins were released into circulation before the error was caught, making them highly scarce and valuable. According to the PCGS CoinFacts, a 1955 double die obverse penny in average circulated condition is worth around $1,318.
Specimens grading Extremely Fine can retail for $7,750 and Mint State examples have sold at auction for as much as $16,600.
1969-S Double Die Obverse Penny
Another famous double die variety is the 1969-S doubled die obverse cent, struck at the San Francisco Mint. Fewer than 100,000 examples were minted before the die was retired, adding to the coin’s popularity.
An average circulated 1969-S doubled die penny sells for approximately $2,000 to $2,500 now. Coins certified by PCGS in gem quality Mint State grades have realized over $30,000 at auction. So always be sure to closely check your 1969 Lincoln cents!
1995 Double Die Obverse Penny
In more modern times, a major doubled die obverse occurred on the 1995 Lincoln cent. Estimates suggest 120,000 to 200,000 of these coins entered circulation, mostly in the Philadelphia region. PCGS says that for a commonly circulated 1995 double die cent, the value is only about $25 to $50.
Though given the large mintage, even MS65 specimens top out around $500 to $600 currently. But there’s always a chance you’ll find one of these modern doubled dies in your pocket change!
Other Notable Examples and Values
While those are probably the three most widely known double-die Lincoln pennies, there are several other varieties as well. According to CoinTrackers, one 1972-D doubled die obverse penny certified MS65 Red sold for nearly $35,000 in 2019!
So carefully checking mint marks of 1960s and 1970s Lincoln cents can pay off.
Some other significant double-die pennies include:
- A 1918/7-D overdate, valued around $850 in Fine condition
- 1920-D & 1937-D DDOs worth $2,000+ in AU/UNC grades
- 1955 doubled die reverse at roughly $300 average value
- 1972 doubled die obverse penny with 15,000 struck, selling for approx. $300 in EF/AU
As you can see, double-die errors add substantial value and appeal to otherwise common Lincoln cents. Checking all your pocket changes carefully could lead to the discovery of a very valuable rarity!
How to Identify a Double Die Penny
What to Look For
When examining a penny for doubling, there are a few key features to look for. Carefully inspect the date, mottoes, and design elements for any signs of doubling, spreading, or overlapping of the metal. Subtle extra thickness or sharpness in the coin’s features may indicate a doubled die error.
Particularly check the lettering, which is most likely to show clear signs of doubling if present.
Using Magnification
Using magnification can make it much easier to identify double details on a coin. An inexpensive coin magnifier, loupe, or even a low-powered microscope can reveal doubling that is barely visible to the naked eye.
With sufficient magnification – 10x to 30x power is ideal – the splitting and overlaying of metal from the doubled minting should become apparent if present on your penny. Be sure to compare both the heads and tails side for any indicators of the error.
Distinguishing Natural Doubling
While evidence of a doubled image on a coin is an exciting find for collectors, be aware that other effects can sometimes resemble minting errors to the untrained eye. For example, the natural flow of metal during minting can lead to harmless effects that may look similar to doubling under magnification.
However, true doubled die errors will show specific signs like sharp splits in design elements, noticeable spreading toward the rim, and clear overlapping of objects or numerals from multiple impressions.
If the doubling lacks these definite characteristics, then it is likely just a natural byproduct of the minting process rather than a genuine error.
Tips for Collecting Double Die Pennies
Know the Years and Mints to Search
When looking for double-die pennies, it’s important to know which years and which mints to focus your search on. The most famous double dies occurred on Lincoln pennies minted in 1955, 1969, 1972, 1983, 1984, 1995, and 2000. The Philadelphia and Denver mints saw the most double dies.
So be sure to check Lincoln pennies from those years and mints to have the best shot at finding a double die!
Examine Lots of Pennies
Finding double-die pennies takes patience and perseverance. You’ll likely have to look through thousands of pennies before coming across a double die. Carefully examine the date and lettering on each penny under a magnifying glass or microscope.
Pay special attention to the lettering as that’s where you’re most likely to spot the doubling effect of a double die error. The more pennies you can sort through, the better your chances. So try getting penny rolls from your bank or checking coin jars and fountains. Persistence pays off!
Join a Coin Collecting Club
Connecting with other coin collectors can be a fun way to learn more about double-die pennies and add to your collection. Local coin clubs often hold meetings where members can buy, sell, and trade coins. You might be able to find double-die pennies that other collectors have already identified.
Club members can teach you how to spot errors like doubled dies and point you to useful resources. And you can make new friends who share your interest in coin collecting. So check online or with your local library to see if there’s a coin-collecting club in your area.
