Last time I was in Calgary, to stay with my aunt and uncle, I mailed a box home to myself. It seemed odd to go into a drug store to mail a box, but what the heck. As I counted through that funny looking change and bills to pay, we got talking about the U.S. quarters for the states. Turned out he was collecting them, so I pulled out my U.S. coin purse and we looked through for those he didn't have. I think he bought five or six from me (we did that at par, much easier and no great benefit or loss at the time.) Rap and Gnu, you should have gone to the mall in Calgary to do your mailing, that guy would have been very helpful because he'll still have warm memories of buying my U.S. quarters.
