Daniel Carr has also minted some fun and interesting Parody State Quarters. http://www.dc-coin.com/index.asp?PageAction=VIEWCATS&Category=3 He has designed several US Coins over the years, he also has a prototype "Amero" coin. The American Euro seems to be his specialty.
It's funny...I ran into those "mature" quarters when I was really little and didn't get some of them...haha...
Looked there to see if he had one for Washington State or North Dakota, and didnt find any. I certainly WOULD not pay the price he is asking for them lol.
