$1.2 Million Sacagawea Dollar – In the world of coin collecting, few stories are as fascinating as that of the $1.2 million Sacagawea Dollar. What started as a routine minting process in the year 2000 led to the accidental creation of one of the rarest and most valuable coins in U.S. history. This coin, which at first glance resembled a mere golden token, became the center of collector frenzy after its discovery. Here’s the complete story of how this accidental masterpiece rose to fame.
The Origin of the Sacagawea Dollar
The Sacagawea Dollar was introduced in 2000 by the U.S. Mint to replace the unpopular Susan B. Anthony dollar. The coin featured a beautiful depiction of Sacagawea, the Shoshone woman who assisted Lewis and Clark on their expedition, carrying her infant son Jean Baptiste.
- Composition: A copper core with manganese-brass outer layer giving it a golden hue
- Size: Same diameter and thickness as the Susan B. Anthony dollar
- Purpose: Revive interest in the dollar coin and honor Native American contributions
Though the coin had historical significance, it failed to gain much traction in everyday commerce due to public preference for paper money.
The Rare Mule Error That Shocked Collectors
In early 2000, a curious mix-up at the U.S. Mint in Philadelphia led to an extraordinary minting error โ a “mule” coin. A mule coin is one that is struck with mismatched dies โ meaning the front and back do not belong to the same coin.

In this case:
- Obverse (front): A George Washington quarter design
- Reverse (back): The Sacagawea dollar eagle reverse
- Metal: Struck on a golden-colored dollar coin planchet
This unintentional combination of a quarter and dollar created a coin that had never been seen before.
How It Was Discovered
The first known example of the error was discovered by Frank Wallis of Arkansas in May 2000. He noticed the odd-looking coin in a roll of dollar coins from his local bank. Word quickly spread through the numismatic community, and experts confirmed the authenticity of the error.
As more examples turned up, collectors realized they had something incredibly rare on their hands. In total, only 19 authentic examples of the mule error are known to exist today.
Why Itโs Worth $1.2 Million
Not all Sacagawea Dollars are worth a fortune. Most are worth face value or slightly more. But the mule error โ a genuine mint mistake โ is an extreme rarity. Here’s why this coin commands such a staggering price:
1. Incredibly Rare
Only 19 of these coins have been authenticated and graded by professional organizations like PCGS and NGC. This scarcity puts them in the elite category of U.S. coinage.
2. Historical Significance
It’s the first known mule error involving coins of different denominations struck for circulation by the U.S. Mint.
3. Demand from High-End Collectors
Wealthy collectors and museums aggressively bid for ultra-rare U.S. coins. In 2021, one such Sacagawea mule dollar graded MS-67 sold for $1.2 million at auction.
4. Mint-Origin Authentication
Since these were struck at the Philadelphia Mint and verified by top grading services, their provenance adds to their legitimacy and value.
