As we have to feed the laundry machines with quarters, I do have an advantage! I also have a US citizen looking for me. I now have all bar the Maine quarter of those issued up to and including 2004. The new one, Connecticut, is out this month, but I think I'll be lucky to find one. My American buddy says he'll send me all those minted in the future as they come out, so I'll end up with a full set! About the only coin series that I can say that !
