In the rarefied world of numismatics, few events spark as much excitement as when a modern coin sells for more than $2 million.
That’s precisely what happened in 2025 when a 2011 Sacagawea Dollar with a reverse rotation error achieved a jaw-dropping $2.2 million at auction.
This remarkable sale highlights how even coins minted for everyday use can become extraordinary collector’s items when they bear the right mistake, in pristine condition, and backed by serious demand.
Why This Sale Broke the Internet
Several compelling factors combined to make this coin a legend overnight:
- Modern yet rare: Unlike famous antique errors, this was a contemporary coin struck just over a decade ago—but incredibly rare due to the error.
- Jaw-dropping rotation error: Its reverse was rotated a full 180 degrees relative to the obverse—an extreme and visually dramatic misalignment.
- Mint condition: The coin remained in flawless state, with no wear or damage—perfect for grading and display.
- Skyrocketing demand: A bidding frenzy erupted among top collectors, driving the price into seven-figure territory.
Understanding the Reverse Rotation Error
A reverse rotation error occurs when the reverse side of the coin is struck improperly, such that when you flip the coin top-to-bottom, one side appears inverted.
This happens when the reverse die is misaligned or rotated in the die setup.
In this extraordinary case, the reverse of the 2011 Sacagawea Dollar was rotated a full 180 degrees relative to the obverse—a rare and highly coveted error that greatly increased its collectible value.
The 2011 Sacagawea Dollar — Why It Matters
Introduced in 2000, the Sacagawea Dollar honored the Shoshone woman Sacagawea, a key guide during the Lewis and Clark expedition.
By 2011, it had become part of the Native American $1 Coin Program, featuring changing reverse designs celebrating Native American heritage.
The 2011 edition depicted the Wampanoag Treaty of 1621, a symbolic tribute to early cooperation between indigenous peoples and settlers.
While millions of these coins were minted, few stand out—making this reverse rotation error vastly unique.
