The 1926 Buffalo Head Nickel DDO DDR is a circulated 5 cent coin made of copper that was struck in a business setting in Philadelphia. This coin features a Buffalo design on the obverse and is part of the Buffalo series of coins from the United States. Despite being ungraded and uncertified, this coin holds historical significance and is a valuable collectible for numismatists interested in US coins from the early 20th century.

Absolutely a stunner of a mint error coin. DDO/DDR. So rare a variety, Fivaz and Stanton record this variety as "Unique" due to so few identified. Clearly, one can see easily see the diagnostics in the close-up photos. No question.
Doubling shows a medium spread on LIBERTY, especially above "IBERT" and within both loops of the "B" and "R". Other letters exhibit the doubling, and a lighter spread on "E PLURIBUS UNUM" on all letters. Considered one of the nicest doubled dies in the series.
