🪙 A Quarter That Isn’t Really a Quarter?
Yes, you read that right. A bizarre and ultra-rare minting mistake—known as a Mule Error—resulted in a coin that combines the head of a Washington Quarter with the tail of a Sacagawea Dollar. This modern error has sold for up to $195,000, making it one of the most valuable U.S. coins struck in the 21st century.
🤯 What Is a Mule Error?
Definition: A coin struck using dies from two completely different denominations.
This Specific Coin:
- Obverse (Front): Washington Quarter
- Reverse (Back): Sacagawea Dollar (soaring eagle)
- Edge: Plain (not reeded like a quarter)
- Size: Larger than a quarter (matches dollar dimensions)
