Many people don’t realise that some old coins can be worth a lot more than their face value. In fact, a few special coins from past years have sold for lakhs or even crores at auctions. One such coin from the year 2000 is extremely rare and was sold for a huge amount of money—all because of a rare mistake at the US Mint.
Why Some Coins Become Valuable
Old coins become valuable mostly because of their uniqueness. If a coin has a minting mistake or was made in small numbers, collectors will pay a high price for it. The United States Mint has made coins since 1793, and sometimes they make rare or unusual coins, either by accident or as limited editions.
The first US Mint was in Philadelphia, but today there are five other locations: Fort Knox, Denver, San Francisco, Washington DC, and West Point. These mints create coins for daily use and also for collectors.
Coins come in two types of strikes. One is the business strike, which is used in regular transactions like buying groceries. The second type is the proof strike, which is made mainly for collectors. Proof coins are shinier, more detailed, and usually not used in everyday life.
The Famous 2000-P Mule Error Coin
One of the most surprising coins to ever come out of the US Mint is the 2000-P Sacagawea Dollar, which was actually made by mistake. This coin is known as a “mule error” coin. A mule error happens when the front side (heads) and the back side (tails) of a coin come from two different types of coins.
In this case, the back of the coin was correctly printed with the design for the Sacagawea Dollar. It had an image of an American Eagle and the words “ONE DOLLAR” and “E Pluribus Unum.” But the front side showed former President George Washington, which is the design for a quarter, not a dollar.
This mix-up happened only in the Philadelphia Mint during the summer of 1999. Only 39 such coins were made as a test, and today, only 12 are kept safely in Fort Knox. One of these rare coins was sold in 2013 for a massive $88,125, which is over ₹73 lakh in Indian currency.
How Did This Happen?
The mistake occurred when the blank coins (called planchets) meant for the Sacagawea Dollar were wrongly used with quarter dies. This rare event created a mismatched coin—one side had the dollar design, and the other had the quarter design. That’s why it’s called a mule coin.
Mule errors are not limited to dollars and quarters. Similar mistakes have happened with Lincoln pennies and Roosevelt dimes. These coins also sell for thousands of dollars at auctions.
Condition Matters: Grading the Coin
Another reason why the 2000-P mule error coin was sold at such a high price is its excellent condition. The coin was graded MS-66 by the Professional Coin Grading Service (PCGS). On the coin grading scale of 1 to 70, a score of 66 means it was almost perfect, with very few marks or scratches.
More Rare Coins That Can Make You Rich
This rare mule error coin is not the only one that’s valuable. Many other coins are worth a lot of money. For example, a Lincoln penny with three special letters on its back was sold for $94,000. There’s even a Liberty nickel that sold for an incredible $4.5 million due to its brilliant, glitter-like surface.
If you ever come across old coins at home, don’t throw them away without checking their details. Sometimes, a small error or a unique design can turn an ordinary-looking coin into something worth lakhs or even crores. Keep an eye out, especially for coins from years like 2000, and learn to spot the signs of rare minting mistakes. You never know—you might be holding a tiny piece of history that could make you rich one day.
