Imagine finding a dollar coin in your wallet that’s worth more than a fancy car or even a house! A rare Sacagawea dollar, thanks to a minting mistake, sold for a whopping $2.1 million in 2025. This golden coin, created to honor a Native American hero, has become a treasure for collectors. But here’s the exciting part: some of these coins might still be hiding in your pocket change. Let’s dive into what makes this coin so special and how you can spot one before you accidentally spend it.
A Coin with a Historic Story
The Sacagawea dollar was first minted in 2000 to celebrate Sacagawea, the Shoshone woman who helped guide the Lewis and Clark expedition across America from 1804 to 1806. The coin, designed by Glenna Goodacre, shows Sacagawea carrying her baby, Jean Baptiste, on her back. Its golden color comes from a manganese-brass alloy, making it stand out from other coins. While most Sacagawea dollars are worth just $1, a few rare ones with unique errors have turned into collector’s gold. The $2.1 million coin is one of these rare finds, and its story is sparking a nationwide hunt.
The Million-Dollar Mistake: The Mule Error
What makes this Sacagawea dollar worth $2.1 million? It’s called a “mule error,” a rare mistake where two different coin designs get mixed up. This coin has the front (obverse) of a Sacagawea dollar but the back (reverse) of a Washington quarter, featuring an eagle meant for a 25-cent coin. This mix-up happened in 2000 at the Philadelphia Mint, and only about 20 of these coins are known to exist. One sold for $2.1 million at a private auction in October 2025, making it one of the most valuable modern U.S. coins.
How to Spot the $2.1 Million Coin
Think you might have one of these treasures? Here’s how to check your Sacagawea dollar:
- Check the Reverse: Look at the back of the coin. A regular Sacagawea dollar has a soaring eagle with 17 stars. If it has the Washington quarter’s eagle design, you might have a mule error.
- Look for the Mint Mark: Find the “P” mint mark under the year 2000 on the front, showing it was made in Philadelphia.
- Inspect the Edge: The coin should have a plain edge, like other 2000 Sacagawea dollars.
- Use a Magnifying Glass: Check for tiny details or odd marks that don’t match a normal dollar coin.
- Weigh It: The coin should weigh about 8.1 grams. If it’s much lighter or heavier, it could be struck on the wrong planchet.
If you think you’ve found a mule, don’t clean it! Cleaning can lower its value. Store it in a protective holder and take it to a professional coin grader like PCGS or NGC to confirm it’s real.
Other Valuable Sacagawea Coins to Watch For
The mule error isn’t the only valuable Sacagawea dollar. Here are a few others that can fetch big money:
| Coin Type | Description | Value Range |
|---|---|---|
| 2000-P Cheerios Dollar | Has detailed eagle tail feathers, found in cereal boxes | Up to $25,000 |
| Wounded Eagle Error | A line on the eagle’s chest looks like a spear wound | Up to $5,160 |
| Susan B. Anthony Planchet | Struck on a silver-colored planchet by mistake | Up to $16,800 |
These coins, especially in great condition, can be worth thousands. The Cheerios Dollar, for example, was part of a 2000 promotion with General Mills, where only 5,500 coins were placed in cereal boxes.
