Unique Feature:
The "Three-Legged Buffalo" error occurred due to excessive polishing of the reverse die at the Denver Mint. This resulted in the buffalo's front right leg appearing entirely missing, leaving only a faint remnant, which made this variety one of the most famous and sought-after errors in U.S. coinage.
Historical Significance:
The Buffalo Nickel series (1913–1938), designed by James Earle Fraser, is iconic for its Native American portrait and American Bison imagery.
The 1937-D 3-Legs error has a unique place in numismatics and is highly valued for its rarity and the story behind its creation.
