That change jar you have on the shelf could pay off in bigger ways than expected.

An error on the 1999 Georgia state quarter has pushed the value of some of the coins to as high as $10,000.

GoBankingRates.com reported Georgia state quarters from 1999 have several types of errors, the biggest of which involves coins struck on experimental metals, called planchets, that were intended for the Sacagawea dollar.

As U.S. Coins Guide noted, Georgia quarters were among the first states to be printed in the series. At the time, the U.S. Mint was working on new metal alloys for coins, including one that had a gold tint that was eventually used for one-dollar Sacagawea coins that came out in 2000.

The mint tested out the new alloy on the Georgia quarters and, while it decided not to use them for those coins, they were released and are now highly valued by collectors. GoBankingRates reported some Georgia quarters on the experimental planchets have sold for as much as $10,000. Another sold for $7,200 in 2022.

Wondering if you are the lucky owner of a special Georgia quarter? You can see some tips for spotting it here. The most obvious will be the color, which will be gold to green as opposed to a regular silver-color.

The 50 State Quarters Program was launched by the U.S. Mint in 1999 with five new coins printed per year in the order the states ratified the Constitution or were admitted to the Union.

The heads side of the coins has the familiar portrait of George Washington that has been used since 1932. The tails side features a design related to that state. In the case of Georgia, it’s an outline of the state with a peach in the middle with the words “Wisdom, Justice and Moderation” on top of the image.
