In the world of numismatics, few coins ignite as much excitement as the legendary 2000 Sacagawea Dollar error coin—a truly one-of-a-kind piece that sold for a staggering $3 million due to its unique production mistake and rarity. With only one confirmed specimen known to exist, this coin has become the stuff of collector legends.
What Makes This Coin Worth $3 Million?
This is no ordinary golden dollar. The ultra-rare example that fetched millions is the result of an extraordinary minting error—what experts refer to as a mule error. In this rare case, the U.S. Mint accidentally paired the obverse (front) of a 2000-P Sacagawea dollar with the reverse of a Washington state quarter.
This means the coin has:
Front: Sacagawea and baby, with “LIBERTY” and “IN GOD WE TRUST”- Back: A reverse that should belong to a quarter—featuring the eagle design or state-specific detail, depending on version
- Metal Composition: Golden dollar (manganese brass) planchet, not standard quarter copper-nickel
It’s a hybrid coin that should never have existed—and yet, somehow, one slipped through.
Background: The Sacagawea Dollar Series
The U.S. Mint introduced the Sacagawea dollar in 2000 to replace the Susan B. Anthony dollar. It featured Sacagawea, the Shoshone woman who guided Lewis and Clark, carrying her baby, Jean Baptiste.
While hundreds of millions of these coins were minted, most remain in circulation or collector hands. But the mule error version—featuring a mismatched reverse design—is unique.
Why Is This Coin So Valuable?
Several factors contribute to its jaw-dropping value:
One of a Kind: Only one confirmed authentic example is known
Mule Error: Extremely rare mistake involving mismatched dies
Certified by Experts: Graded and authenticated by PCGS and Numismatic Guaranty Company (NGC)
Elite Ownership: Once part of a prominent private collection and featured in major coin exhibitions
Investment Value: Its rarity makes it more desirable than many rare gold or silver coins
Where Was It Found?
This incredible coin was reportedly discovered in a batch of new dollar coins delivered to a vending machine company. The lucky finder had it examined by professional graders and later consigned it to auction—where it sold for a mind-blowing $3 million.
Could You Find One?
While the odds are incredibly low, it’s not impossible for other similar errors to surface. Coin collectors and treasure hunters are advised to:
Check Your Pocket Change: Look closely at all dollar coins from 2000
Inspect Reverse Details: Make sure the reverse matches a Sacagawea dollar—not a quarter!
Buy Unsearched Rolls: Sometimes these error coins hide in rolls of coins from banks or auctions
Consult the Experts: If you think you found one, contact PCGS or NGC immediately
