Manufacturing errors might be annoying when it comes to most products, but they are a big moneymaker when it comes to collectibles. Errors increase the value of collectibles because a limited number go into circulation before the error is spotted and corrected. For evidence, look no further than a 1999 Georgia quarter whose value has been estimated as high as $10,000 due to errors.

Georgia state quarters from 1999 have several types of errors, according to the U.S. Coins Guide website. The biggest error involves coins struck on experimental metals, called planchets, intended for the Sacagawea dollar.

As U.S. Coins Guide noted, the Georgia and other state quarters were minted in 1999 when the U.S. Treasury first began the state quarters program. This took place just as the U.S. Mint was working on a new metal alloy for coins. The alloy had a gold tint that was eventually used for the one-dollar Sacagawea coins that came out in 2000.

“Curious how the alloy would look on quarters, a bunch of Georgia state ones were minted using it,” the U.S. Coins Guide said 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.”
