As many as 50,000 Wisconsin state extra leaf quarters were issued accidentally by the Denver Mint in 2004. Two error varieties exist: the low leaf variety, which depicts an arched leaf jutting out sideways on the reverse of the coin; and the high leaf version, which shows an additional leaf poking out of the cheese wheel that touches the corn husk leaf. They are worth up to $400 each, so if you find one in your change make sure you hang onto it!
