Imagine finding a coin in your collection that looks ordinary at first glance — only to learn it’s worth millions. That’s exactly what happened with the rare 2011 Sacagawea Dollar with a reverse error, a coin so unusual it recently sold for a jaw-dropping $2.2 million at auction. Could a hidden treasure like this be sitting in your pocket change?
What Is the Rare 2011 Sacagawea Dollar Error?
The coin in question is a 2011 Sacagawea Dollar with a shocking mint mistake: the reverse design, instead of showing the usual Native American theme, features a mismatched die strike more commonly associated with other U.S. coinage. This kind of mule error — when two different coin designs are accidentally paired — is one of the rarest mistakes in U.S. Mint history.
The Surprising History of Mule Coins
Mule coins have fascinated collectors for decades. The most famous is the 2000 Sacagawea Dollar / State Quarter mule, which sold for tens of thousands of dollars. The 2011 version, however, stands apart. Experts believe only a handful exist, making it a true rarity in the numismatic world.
