This 1999 state coin is worth $10,000. Here’s how to check if you have one.

STATEN ISLAND, N.Y. — Pull out that change jar and take a closer look: An error on the 1999 Georgia state quarter has increased the value of the coin, making some of the pieces worth a whopping $10,000.

According to GoBankingRates.com, the 24-year—old coins have several types of errors, the biggest of which involves those struck on experimental metals, called planchets, that were intended for the Sacagawea dollar.

“Curious how the alloy would look on quarters, a bunch of Georgia state ones were minted using it,” the U.S. Coins Guide noted in a blog. “The Treasury decided not to go with the alloy on quarters, but the ones minted with it were still released and are now very much desired by collectors.”

Georgia quarters on the experimental planchets have sold for as much as $10,000, the blog reported, and one sold for $7,200 in 2022.

Wondering if you are the lucky owner of a special Georgia quarter? GoBankingRates said to look for these characteristics:

• Weighs between 5.9 and 6.3 grams on a coin scale, which is more than the 5.67 grams for a typical copper-nickel clad quarter
• Appears thicker than normal
• Has a golden or greenish color, similar to Sacagawea dollars
• Lacks the copper (orange-colored) stripe on the edge of the coin
• Lacks some or all of the edge reeding (e.g. ridges)
• Has a thicker rim than normal (a coin’s rim refers to the raised ridge encircling the circumference of the obverse and reverse of a coin, according to Professional Coin Grading Services)
