Technical Breakdown: Physics, Metallurgy & Die Diagnostics
In 1969, mintmarks were hand-punched into the working die AFTER hubbing was finished. Therefore, a true doubled die CANNOT have a doubled mintmark!
Causes increasing lateral separation toward the rims: maximum spread on the date and motto.
Documented Benchmark Auction Records
Blazing original red luster, pristine satiny surfaces, unmistakable bold doubling on date and motto.

Frequently Asked Questions
Why is the 1969-S Doubled Die Lincoln Cent so famous?
The 1969-S DDO-001 (FS-101) is one of the most valuable and dramatic modern varieties in American numismatics. With fewer than 100 genuine specimens known, it commands $25,000 to over $125,000 at auction. Its fame was amplified by a dramatic 1970 Secret Service investigation.
What happened during the 1970 Secret Service confiscation?
In 1969–1970, two counterfeiters named Roy Gray and Morton Goodman flooded the country with counterfeit 1969 doubled die cents. When collector Cecil Moorhouse found a genuine 1969-S doubled die in change and sent it to the Treasury, government agents thought it was one of the counterfeiters' coins and confiscated it. The Treasury later verified it was a genuine U.S. Mint error and returned it to Moorhouse with an official apology.
What is the #1 rule to identify a genuine 1969-S Doubled Die?
THE 'S' MINTMARK MUST NOT BE DOUBLED! In 1969, the San Francisco 'S' mintmark was punched by hand into the working die AFTER the die was hubbed. On a genuine DDO-001, the date and all lettering show dramatic doubling, but the 'S' is completely single and sharp. If the 'S' is doubled, it is machine doubling worth 1 cent!
What is the difference between true hub doubling and machine doubling?
True hub doubling occurs during die manufacture and creates two distinct, rounded, embossed images with separated serifs. Machine doubling (strike doubling) occurs when the coining press die shifts or bounces during the strike, shearing off metal and creating a flat, shelf-like step that reduces the thickness of letters.
How many genuine 1969-S DDO-001 cents exist?
Major third-party grading services (PCGS and NGC) have combined certified populations of fewer than 75 to 90 genuine coins across all circulated and mint state grades.
Could a genuine 1969-S Doubled Die still be found in pocket change or coin rolls?
Yes! Several examples have been discovered by coin roll hunters over the past twenty years, including an AU-55 specimen found in Michigan that sold for over $40,000.
How much is a genuine 1969-S DDO-001 worth today?
In Very Fine to Extremely Fine condition, genuine certified examples sell for $15,000 to $25,000. In About Uncirculated (AU-50 to AU-58), they command $35,000 to $50,000. In uncirculated Mint State Red (MS-63 to MS-64 RD), they fetch between $65,000 and $130,000+.
