I just thought I would pass this information on to you error coin collectors! In my search for some of the many Doubled Die Varieties showing up in the Minnesota State Quarters, I found another fairly unique error. Instead of finding an extra tree in the area where the DDR #1 extra tree should be, I found a Counter-Die Clash of Washington's Ear instead. There is also some sort of Die Clashing or Counter-Die Clashing around Washington's Ear on the Obverse but I need to get a nice Microscope to really figure out what it actually is. Frank
