The Sacagawea Dollar: A Brief History
Introduced in 2000, the Sacagawea Dollar was the U.S. Mint’s first major attempt to replace the short-lived Susan B. Anthony Dollar (1979–1981, 1999). Featuring a golden-colored manganese-brass composition, the coin honors Sacagawea, who played a vital role in the Lewis and Clark expedition of 1804–1806. The obverse, designed by Glenna Goodacre, depicts Sacagawea carrying her infant son, Jean Baptiste, while the reverse, designed by Thomas D. Rogers, shows a soaring eagle with the inscription “UNITED STATES OF AMERICA” and “ONE DOLLAR.”
Millions of Sacagawea Dollars were minted, and they remain in circulation today, often overlooked as mere pocket change. However, certain rare variants and errors have elevated the coin’s status in the numismatic world. The most famous of these is the 2000-P mule error, a coin that combines mismatched designs from two different denominations, making it one of the rarest modern U.S. coins.
What Is a Mule Error?
A “mule” error occurs when a coin is struck with dies intended for two different denominations, resulting in a hybrid that should not exist. In the case of the 2000-P Sacagawea Dollar, the error happened at the Philadelphia Mint (denoted by the “P” mint mark) during the transition from Susan B. Anthony Dollars to Sacagawea Dollars in late 1999 to early 2000. A Washington quarter obverse die, featuring George Washington’s portrait, was accidentally paired with a Sacagawea Dollar reverse die, showing the soaring eagle. The coin was also struck on a quarter planchet, which is smaller and silver-colored compared to the golden Sacagawea planchet.
This mismatch created a coin with the front of a Washington quarter and the back of a Sacagawea Dollar—a combination that slipped through the U.S. Mint’s quality control. Experts estimate that fewer than 20 authentic examples exist, most of which are now in private collections or museums. The rarity, combined with the coin’s pristine condition (often graded MS-64 to MS-67 by services like PCGS or NGC), has driven its value to extraordinary heights, culminating in the record-breaking $2.1 million sale in 2025.
Why Is the Mule Error So Valuable?
Several factors contribute to the astronomical value of the 2000-P Sacagawea mule error:
-
Scarcity: With only about 20 known specimens, the coin is exceptionally rare. Most were discovered shortly after minting, and the U.S. Mint quickly corrected the error, ensuring no further mules were produced.
-
Historical Significance: The mule error marks a rare mistake during a transitional period in U.S. coinage, adding to its allure as a piece of minting folklore.
-
Condition: High-grade examples, certified by professional grading services like the Professional Coin Grading Service (PCGS) or Numismatic Guaranty Corporation (NGC), command premium prices due to their pristine condition.
-
Collector Demand: The growing interest in modern coin errors, fueled by high-profile auction sales, has driven demand for unique pieces like the Sacagawea mule.
The $2.1 million sale in October 2025, reported by sources like USA Today, set a new record for modern U.S. coin errors, surpassing previous sales of similar mules (e.g., one sold for $150,000 earlier in 2025). This sale has reignited public interest, with collectors and casual enthusiasts alike scouring their change for a potential jackpot.

How to Spot a Rare Sacagawea Dollar
Spotting a valuable Sacagawea Dollar requires a keen eye and some basic knowledge. Here’s what to look for:
-
Mule Error (2000-P):
-
Obverse: Features George Washington’s portrait (from a Washington quarter) instead of Sacagawea.
-
Reverse: Shows the Sacagawea eagle design with “ONE DOLLAR.”
-
Planchet: Silver-colored, smaller than a standard Sacagawea Dollar, with reeded edges typical of quarters.
-
Mint Mark: Look for the “P” (Philadelphia Mint) on the obverse.
-
-
Cheerios Variant:
-
Check the reverse for enhanced, sharply detailed eagle tail feathers, unlike the standard design.
-
Often found in original Cheerios packaging from 2000, though some circulated.
-
-
Wounded Eagle:
-
Look for a die gouge on the eagle’s wing on the reverse, resembling a scratch or wound.
-
Common in 2000-P coins but requires grading for high value.
-
-
Gold Planchet Mule:
-
Heavier and shinier than standard Sacagawea Dollars, with a distinct gold hue.
-
Extremely rare; often mistaken for tokens due to their unique appearance.
-
To check your coins, use a magnifying glass to examine details like mint marks, edge reeding, and design anomalies. If you suspect you have a rare coin, do not clean or handle it excessively, as this can reduce its value. Instead, contact a reputable coin dealer or grading service like PCGS or NGC for professional evaluation.
Where Might You Find These Coins?
The allure of the Sacagawea mule error lies in its potential to be hiding in plain sight. Some notable discoveries include:
-
Bank Rolls: The first known mule was found in a roll of dollar coins from a bank in 2000.
-
Parking Meters: A 2000-P mule valued at $900,000 was reportedly found in a parking meter’s change return in Ohio in May 2025.
-
Lost-and-Found: A gold planchet mule worth $920,000 was discovered in a school’s lost-and-found box in Washington state.
-
Yard Sales: A mule error valued at $7.5 million was allegedly spotted at a yard sale, though this claim is unverified and likely exaggerated.
These stories highlight the possibility that rare coins could still be in circulation, tucked away in coin jars, wallets, or cash registers. However, the U.S. Mint has tightened quality control since 2000, making such errors less likely today.
Tips for Collectors and Enthusiasts
If you’re inspired to hunt for a rare Sacagawea Dollar, here are some practical steps:
-
Join Coin Communities: Local coin clubs and online forums like the PCGS or NGC websites offer tips, updates, and authentication advice.
-
Stay Informed: Follow numismatic news on platforms like Coin World or USA Today for auction results and market trends.
-
Check Your Change: Examine dollar coins from the early 2000s, especially those with a “P” mint mark. Look for unusual designs, weights, or colors.
-
Visit Coin Shows: Events like the American Numismatic Association’s World’s Fair of Money provide opportunities to learn and trade.
-
Authenticate Finds: If you suspect you’ve found a rare coin, have it graded by PCGS or NGC to confirm authenticity and value. Store it in a plastic coin holder to preserve its condition.
The Broader Context of Rare Coin Collecting
The $2.1 million Sacagawea mule sale is part of a broader surge in interest in rare U.S. coins. Other notable examples include:
-
1943 Bronze Lincoln Cent: Struck in copper instead of wartime steel, one sold for $1.7 million in 2010 (equivalent to $2.3 million in 2025).
-
1976 Bicentennial Quarter: Rare silver proof versions have sold for over $20,000.
-
1969-S Doubled Die Roosevelt Dime: A recent find in Ohio was valued at $1.5 million.
These stories underscore the potential for life-changing discoveries in everyday change. However, collectors should be cautious of exaggerated claims, such as a Sacagawea Dollar supposedly worth $7.5 million or a Lincoln Penny valued at $3 billion, which lack credible evidence and may be speculative.
The Future of the Sacagawea Dollar
The Sacagawea Dollar remains in limited circulation, often overshadowed by paper currency. Its historical significance, tied to Sacagawea’s legacy, and the allure of rare errors ensure its place in numismatic history. The U.S. Mint continues to produce Sacagawea Dollars with updated reverse designs (e.g., the Native American Dollar series), but none have matched the fame of the 2000-P mule.
As coin collecting grows in popularity, driven by viral stories and high-profile auctions, more Americans are checking their change for hidden treasures. The $2.1 million Sacagawea mule serves as a reminder that even in the digital age, physical currency can hold extraordinary value. So, the next time you receive a golden dollar in change, take a closer look—it might just be worth a fortune.
