In December 1997, America's most adventurous coin program became a reality when President Clinton signed legislation authorizing the U.S. Mint to issue the innovative 50 State Quarters collection. Starting in January 1999, each of the 50 states in the Union will be honored on a unique Quarter Dollar commemorative coin. Five states were featured each year, based on the order in which they ratified the Constitution or became states. On the front, otherwise known as the obverse, the mintmarks can be found to the right of George Washington's portrait. The small "S" indicates San Francisco Mint.

The Wisconsin State Quarter is the fifth and final State Quarter of the year 2004. It also brings to an end the 6th year in the planned ten-year collection that will eventually feature all 50 states. Wisconsin was the 30th state, so this coin is the 30th overall in this collection. Wisconsin is now renowned as the Dairy Capital of the World, so it is appropriate for the Wisconsin State Quarter to feature the head of a cow and a round of cheese. The coin design also shows an ear of corn to symbolize the fact that Wisconsin is a leading corn producer. The design is completed with the state motto, Forward, which was officially adopted in 1851.

Each coin is encapsulated - please keep the coins in their protective coin holder to maintain their condition.
