What Is a Doubled Die?
A doubled die occurs when a coin die receives a misaligned second impression from the hub during the die-making process. This creates a die with doubled design elements — every coin struck from that die shows the same doubling. True doubled dies are consistent, collectible, and often very valuable.

True Doubled Die vs Machine Doubling
True doubled die (valuable): Doubling is on the die itself. Shows as shelf-like separation with distinct, sharp doubled elements. Consistent across all coins from that die.
Machine doubling (worthless): Caused by die bounce during striking. Shows as flat, shelf-like distortion. No sharp separation. Often called "worthless doubling" — adds no value.
Key diagnostic: true doubled dies show rounded, separated serifs on letters. Machine doubling shows flat, smeared shelving.
