1955 Doubled Die Obverse

The 1955 Doubled Die Obverse Lincoln cent is one of the most famous and visually dramatic error coins ever produced by the United States Mint. The doubling is not subtle. The date, IN GOD WE TRUST, and LIBERTY are all visibly doubled, with the secondary image offset strongly enough to be seen without magnification on any well-preserved example. Pick up a 1955 DDO and the doubling jumps off the coin. No loupe needed. No guessing.

The error occurred during the hubbing process. The working die received two impressions from the hub, with the second impression rotated slightly from the first. Every coin struck from that die carries the same dramatic doubling. Approximately 40,000 were struck from a single die pair. About 24,000 entered circulation, primarily through cigarette vending machines in the New England area. The remaining 16,000 were discovered in the press operator's bin and destroyed. The error was allowed to pass in part because of a coin shortage along the Atlantic coast caused by Hurricanes Connie and Diane that summer. Coin dealer James Ruddy advertised in Johnson City, New York, offering 25 cents per example but was swamped with responses and had to stop buying. Q. David Bowers established a shell company to maintain a two-way market, starting at $7.95 per coin.

The 1955 DDO is the coin that introduced the concept of doubled dies to mainstream coin collecting. Before 1955, doubled dies were a specialist concern. After 1955, every collector knew to check their Lincoln cents for doubling. The coin created a market for doubled die varieties that has sustained for seven decades. A 1955 DDO in Fine to Very Fine condition trades in the low-to-mid four figures. Uncirculated examples with red surfaces reach five figures. A gem MS65 Red was sold at auction for over $100,000.

Counterfeits exist. The most common fakes are machine-doubled coins (which show a different type of doubling caused by die bounce during striking, not a hubbing error) that are sold to unsuspecting buyers as the genuine DDO. The distinction is in the character of the doubling: genuine hub doubling shows clear, distinct secondary images with full letter and numeral detail; machine doubling shows flat, shelf-like marks without complete letter forms. Certification by PCGS or NGC confirms the genuine DDO and provides the market confidence that supports the variety's substantial price.
