If you're like most people, you probably toss your spare change into a jar, bowl, or piggy bank at home. But did you know that some of those coins could be worth a lot of money?

One type of coin to look for is a rare quarter. A 2000 quarter minted with an error recently sold for $216 on eBay. The coin is part of the state Washington quarters series featuring New Hampshire, but it was struck onto a Jefferson nickel.

According to USA Coin Book, rare Washington quarters minted in 1932 can sell for as much as $13,573. Errors and rare mintages give coins the highest re-sale value.

Error coins — like the Washington quarter which recently sold for $216 — are sometimes called double denominations or “planchet” errors. The mistake occurs to a blank coin (a “planchet”) during the minting process.

Errors can happen when the wrong planchet is fed into the minting press, or the machine contains dies of different denominations, and a mix-up occurs.

To check if your coins are valuable, first look for any that seem unusual, such as a design you've never seen, an error where the print looks “off,” or the wrong denomination printed on the coin. Don't forget to check both sides.

Then search the full name and year of the coin on eBay, select “sold” items, and sort the results by “highest value” first. If you find a winner, you can sell it on eBay or through a variety of other online marketplaces.
