Rare Wisconsin Quarter discovered

The numismatic world is all abuze about the latest US Mint error, the Wisconsin Commerative Quarter minted in 2004 bears the image of a cow, a wheel of cheese and a half-husked ear of corn. There is something peculiar about the cheese head coins . . . there are variations in the placement of leaves surrounding the coin's ear of corn. Collectors have identified two varieties. There is a an offer by several Arizona dealers for as much as $1499 for a perfect specimen.
