1970-S DDO Penny: The Rare Doubled Die Lincoln Cent Worth Thousands
The 1970-S DDO Penny is one of the most valuable Lincoln cent varieties from the 1970s. At first glance, it looks like a regular 1970 penny with an “S” mint mark. But if it is the real doubled die variety, this small copper cent can be worth hundreds, thousands, or even tens of thousands of dollars in high grades.

This coin is officially known by collectors as the 1970-S DDO-001 Lincoln Cent, the 1970-S Doubled Die Obverse, and the 1970-S FS-101. Those names all point to the same major variety: a 1970-S Lincoln Memorial cent with strong doubling on the front of the coin.
For coin collectors, this is not just another penny. The 1970-S DDO Penny is a serious variety that belongs on every error coin hunter’s radar.
What Is the 1970-S Doubled Die Penny?
The 1970-S DDO Penny is a Lincoln Memorial cent struck at the San Francisco Mint. The “S” mint mark under the date shows that it was made in San Francisco.
The letters “DDO” stand for Doubled Die Obverse. That means the doubling appears on the obverse, which is the front side of the coin with Abraham Lincoln’s portrait.
A true doubled die happens during the die-making process. The die itself carries a doubled design, and then that doubled design is struck into the coins. That is different from machine doubling, damage, or normal wear.
On the real 1970-S DDO Penny, the doubling is strongest on:
IN GOD WE TRUST
LIBERTY
The date, 1970
This is one of the reasons collectors want this variety so badly. The doubling is strong, collectible, and recognized by major coin variety references.
Why the 1970-S DDO Penny Is Valuable
The 1970-S DDO Penny is valuable because it is a major doubled die variety with strong visible doubling and strong collector demand.
Not every 1970-S penny is rare. In fact, most 1970-S pennies are common. The valuable one is the specific doubled die variety known as DDO-001 or FS-101.
Several things help determine the value:
Condition
A worn coin may still have value if it is genuine, but high-grade coins are worth much more.
Color
Copper pennies are often graded as Brown, Red-Brown, or Red. Red examples usually bring the most money.
Authentication
A certified example from a major grading company can sell for much more than a raw coin because buyers know the variety is real.
Eye appeal
Spots, scratches, corrosion, cleaning, and damage can lower the value.
High-grade examples of the 1970-S DDO Penny have sold for thousands of dollars. Some top examples have reached five-figure auction prices. That is why this penny gets so much attention from collectors.
How to Identify a 1970-S DDO Penny
To identify a possible 1970-S DDO Penny, start with the basics.
First, the coin must be a 1970-S Lincoln cent. Look for the “S” mint mark under the date.
Second, the famous variety is connected to the Large Date style. This is important because 1970-S cents can be found with different date styles, and beginners often confuse them.
Third, check the obverse for strong doubled die details.
The most important areas to inspect are:
IN GOD WE TRUST
The motto at the top of the coin is one of the strongest places to look for doubling. On a genuine 1970-S DDO Penny, the letters should show clear doubled die separation.
You are not looking for shadows, scratches, or flat shelf-like doubling. You are looking for real raised doubling that is part of the design.
LIBERTY
The word LIBERTY is another major pickup point. Look closely at the letters. A real doubled die should show clear separation and strong doubling.
If the doubling looks flat, smeared, or like it was pushed to the side, it may be machine doubling instead of a true doubled die.
The Date 1970
The date is another important area. The numbers should show signs of doubled die doubling, especially when viewed under magnification. There is also a die scratch that runs through the 0 of the date on most examples. This is another good way to identify this variety.
Do not rely on phone zoom alone. A 10x loupe or digital microscope makes a huge difference.
1970-S DDO Penny Large Date vs. Small Date
One of the most important details about the 1970-S DDO Penny is the date style.
The valuable 1970-S DDO-001 / FS-101 variety is associated with the Large Date obverse. That means you need to confirm the correct date style before assuming you have the valuable doubled die.
This is where many beginners make mistakes. They find a 1970-S penny, see something strange on the date, and immediately think it is rare. But the date style has to match the known diagnostics for the real variety.
Before you get excited, compare your coin to trusted references and known examples of the genuine 1970-S DDO Penny.
1970-S DDO Penny vs. Machine Doubling
This is the part that trips up almost everybody at first.
A real 1970-S DDO Penny has true doubled die doubling. That means the doubling came from the die itself.
Machine doubling is different. Machine doubling happens during the striking process and usually creates a flat, shelf-like appearance. It can look dramatic, but it normally does not carry the same value as a true doubled die.
Here is the simple version:
True doubled die: raised, rounded, separated doubling that is part of the design.
Machine doubling: flat, shelf-like, pushed, smeared, or scraped-looking doubling.
Machine doubling is common. The 1970-S DDO Penny is not.
That is why you should never identify this coin from one blurry picture. You need clear magnified photos and strong diagnostics.
How Much Is a 1970-S DDO Penny Worth?
The value of a 1970-S DDO Penny depends heavily on grade, color, surface condition, and authentication.
A lower-grade circulated example may be worth hundreds or more if genuine. A high-grade Mint State example can be worth thousands. A top-grade Red example can bring much more.
But there is a major warning here:
Online asking prices are not the same as real value.
Just because someone lists a 1970-S penny for $5,000 does not mean it is worth $5,000. Anyone can ask anything online. Real value comes from completed sales, professional authentication, and actual collector demand.
If you think you found a genuine 1970-S DDO Penny, do not clean it, do not scratch at it, and do not try to “make the doubling show better.” Leave it alone and compare it carefully to known examples.
Should You Get a 1970-S Doubled Die Penny Graded?
If your coin strongly matches the real diagnostics, professional grading may be worth it.
A certified 1970-S DDO Penny is much easier to sell than a raw coin because buyers want proof. Authentication confirms that the coin is actually the FS-101 doubled die variety and not machine doubling or damage.
However, do not send every 1970-S penny to a grading company. Most are common, and grading fees can add up fast.
Before submitting, check:
The date and mint mark
The Large Date style
Doubling on IN GOD WE TRUST
Doubling on LIBERTY
Doubling on the date
Surface condition
Signs of cleaning or damage
If everything lines up, then grading may be the next smart move.
Best Tools for Finding a 1970-S DDO Penny
To search for a 1970-S DDO Penny, you need the right tools.
10x coin loupe
A basic coin loupe helps you inspect the date, mint mark, lettering, and doubling.
Digital microscope
A digital microscope is even better for variety hunting. It lets you zoom in, take pictures, and compare your coin to known examples.
Good lighting
Bad lighting can create fake shadows that look like doubling. Use steady lighting and check the coin from different angles.
Digital scale
A scale can help confirm the coin’s weight. This does not prove the doubled die variety, but it can help verify the coin itself.
Reliable references
Use trusted variety websites, coin books, and grading company resources. Do not rely only on social media comments or random online listings.
Where Can You Find a 1970-S DDO Penny?
Finding a real 1970-S DDO Penny is not easy, but it is possible. These coins can still hide in older collections and forgotten penny groups.
Good places to search include:
Old penny jars
Inherited coin collections
Estate sale coin lots
Bank rolls
Coin albums
Old Lincoln cent folders
Dealer junk bins
Memorial cent rolls
Collections that have not been searched for varieties
The odds are not huge, but that is what makes the hunt exciting. Someone who knows what to look for has a much better chance than someone who sees every penny as just pocket change.
Common Mistakes When Searching for the 1970-S DDO Penny
A lot of people misidentify this coin. Here are the biggest mistakes to avoid.
Thinking every 1970-S penny is rare
Most 1970-S pennies are common. The valuable one is the specific DDO-001 / FS-101 variety.
Confusing machine doubling with a doubled die
Machine doubling can look exciting, but it is not the same as a true doubled die.
Ignoring the Large Date detail
The famous 1970-S DDO Penny is tied to the Large Date style.
Trusting online asking prices
A wild listing price does not prove value. Look at verified sales instead.
Using blurry photos
If the doubling cannot be clearly seen, serious buyers will not take it seriously.
Cleaning the coin
Never clean a coin you think may be valuable. Cleaning can destroy the value fast.
How to Take Photos of a Possible 1970-S DDO Penny
If you think you found a 1970-S DDO Penny, clear photos are important.
Take photos of:
The full front of the coin
The date and mint mark
IN GOD WE TRUST
LIBERTY
The full back of the coin
Any marks, scratches, or damage
Use good lighting and avoid glare. Take straight-on photos and close-up magnified photos. The goal is to show the diagnostics clearly, not to create shadows that make the coin look more dramatic than it really is.
Final Thoughts on the 1970-S DDO Penny
The 1970-S DDO Penny is one of the best Lincoln cent varieties from the Memorial cent era. It is valuable, collectible, and exciting because it proves that a small penny can still carry serious money when it has the right variety.
But this is also a coin that requires careful identification. Most 1970-S pennies are not the famous doubled die. Many coins that look doubled are only machine doubling or damage.
If you find a 1970-S penny, inspect it closely. Check the Large Date style. Look for strong raised doubling on IN GOD WE TRUST, LIBERTY, and the date. Compare it with trusted references. And if it matches the real diagnostics, consider professional authentication.
The 1970-S DDO Penny is exactly why coin hunting is so addictive.
Because sometimes the coin everyone else spends is the one a collector would love to buy
