The world of rare U.S. coins is filled with fascinating stories, but few match the intrigue of the 2000-P Sacagawea Dollar with a Mule Error.
This unintentional mint mistake became one of the most desirable modern coin rarities in American numismatics. Recently selling for $192,000 at auction, this coin has left collectors and experts in awe, not just for its value but for the incredible story behind its creation.
What Is the 2000-P Sacagawea Dollar Mule Error?
The 2000-P Sacagawea Dollar Mule Error is a coin that features the obverse of a Washington quarter and the reverse of a Sacagawea dollar.
The term “mule” in coin collecting refers to a coin struck with obverse and reverse dies that were not intended to be paired together. This particular mule error is the first known mule error struck by the U.S. Mint using dies from two different coin denominations.
Instead of showing the expected portrait of Sacagawea on the front, this unusual coin features George Washington’s profile, the same one seen on standard quarters.
The reverse, however, depicts the familiar soaring eagle design used on Sacagawea dollars. Even more bizarre, the edge is smooth, matching the dollar format, not the reeded edge of a quarter.
Discovery and Public Reaction
The first known specimen of this mule coin was discovered in the year 2000 by a coin collector in Arkansas who had received it in a Cheerios cereal box promotional coin set.
Since then, several more have surfaced, but they remain extremely rare.
As of 2025, only 21 confirmed examples of this mule error are known to exist. Each one has fetched an impressive price at auction, but the most recent sale in 2022 brought the highest recorded amount: $192,000 for a superbly preserved, graded example.
Why Is This Coin So Rare?
The rarity of this coin lies in its accidental creation and the combination of mismatched dies. It is widely believed that the Philadelphia Mint accidentally paired the quarter obverse die with the dollar reverse die during production. The result was a coin that was never supposed to leave the Mint, let alone enter circulation.
Furthermore, the limited number of verified examples adds to its mystique. No official U.S. Mint documentation confirms how many of these were produced or how they escaped into circulation, which only fuels collector interest.
Coin Grading and Market Value
Most of the known examples of the 2000-P Sacagawea Dollar Mule Error are in Mint State (MS) condition, with several achieving grades of MS65 or higher.
Top-tier grading from agencies like PCGS or NGC significantly boosts the value of any rare coin, and this one is no exception.
In private sales and public auctions, prices for this mule error have ranged between $75,000 and $192,000, depending on grade, provenance, and market conditions.

The Mystery Behind Its Existence
Numismatic experts still debate how this error occurred without being immediately caught. Unlike typical mint errors such as off-center strikes or doubled dies, a mule error involving different denominations is an extreme rarity.
Some speculate that the mix-up happened during a coin die test, and a small batch accidentally went into production.
Because it involves two entirely different denominations, the coin defies standard production rules, making its survival and discovery even more astonishing.
