Frequently Asked Questions
How was the famous 1955 Doubled Die Lincoln Cent created?
During the preparation of a working obverse die in late 1955, an annealing technician received an obverse die after its first impression from the master hub. When placing the die back under the hydraulic hubbing press for its second impression, the die was rotated roughly 2.5 degrees out of alignment, impressing a completely doubled image into the steel die.
Why did the Mint release the 1955 doubled die coins if they knew about them?
The defective die struck an estimated 20,000 to 24,000 coins during a night shift before being discovered. Those coins had already fallen into a massive hopper containing over 500,000 normal cents. Mint officials decided that destroying over half a million coins to weed out 20,000 errors would be a waste of taxpayer money, so the entire batch was bagged and shipped.
Where were the 1955 doubled die cents first discovered?
The vast majority of the 1955 doubled dies were distributed in upstate New York and western Massachusetts. Many were loaded into cigarette vending machines as change, where customers noticed the dizzying optical effect and began hoarding them.
What is the 'Poor Man's Doubled Die'?
The 'Poor Man's Doubled Die' is NOT a true doubled die. It is a common 1955 Lincoln cent struck from a severely worn die where metal erosion created a flat, ghost-like halo behind the second '5' in the date. The motto and 'LIBERTY' show zero doubling. It is worth only $2 to $5.
What are the key diagnostics of a genuine 1955 DDO-001?
1. All four digits in '1955', all letters in 'LIBERTY', and all letters in 'IN GOD WE TRUST' show massive, full separation with rounded serifs.\n2. Lincoln's eyelid is distinctly doubled.\n3. On the reverse, a faint vertical die scratch runs down from the left crossbar of the 'T' in 'CENT'.
How can you detect a fake 1955 doubled die?
Fake 1955 doubled dies are typically cast replicas or Chinese spark-erosion counterfeits. They exhibit soft, mushy details, porous surfaces under 20x magnification, lack of cartwheel luster, incorrect copper weights (under or over 3.11 grams), and miss the diagnostic reverse die scratches.
How much is a genuine 1955 DDO-001 worth today?
In circulated condition (Good-4 to Fine-12), a genuine certified specimen sells for $1,200 to $1,800. In About Uncirculated (AU-50 to AU-58), it brings $2,800 to $4,000. In uncirculated Mint State Red (MS-64 to MS-65 RD), values skyrocket to $15,000 to over $125,000 at auction.
