US State Quarters

I'm collecting the US state quarters. I am missing only three two quarters from the Philadelphia mint: Arizona, Alaska, and Hawaii. The Denver mint is a different story. I am missing these:

Missing Denver mint quarters

Year	States
1999	Pennsylvania
2001	Rhode Island
2003	Illinois, Missouri
2004	Michigan, Iowa, Wisconsin
2005	California, Oregon, Kansas
2007	Montana, Wyoming
2008	New Mexico, Arizona, Alaska, Hawaii

In New York, the quarters in circulation are overwhelmingly from Philadelphia. By my estimate, the Philadelphia coins are 90% of the state quarters and Denver are 10%, so collecting Denver coins is much harder.

I have extras of these Philadelphia quarters available for trading: Iowa, Illinois, Pennsylvania, Kansas, and New Mexico. I've noticed that these coins are encountered less frequently than other Philadelphia mint coins. Please contact me if you are interested in a trade for a coin I don't have.
