When you hear this news, you're almost certainly going to break open your piggy bank to look for a certain quarter.

The talk among coin collectors is that there is a tiny mistake on some but not all Wisconsin state quarters. That makes this 25-cent coin worth more than two bits.

A normal Wisconsin quarter features a cow, a block of cheese, and an ear of corn. But during the minting of the 2004 D-series, an extra leaf appeared on the bottom left side of the corn. A low leaf and a high leaf are extremely rare.

The U.S. Treasury Department says the bulk of these quarters was released in Ohio and Arizona.

If you find one of 50,000 in circulation, it'll have a little bit of wear on it. It's probably worth around $50.

Wisconsin quarters with the extra leaf are fetching hundreds of dollars on eBay.
