I first got a 55 wheatie in change at walmart. Great shape. I just stood and rolled it over in my hands. The teller must of thought I was nuts. Then today when I emptied some of my vending machines( a side hobbie/job) I went thru the bag of quarters and there was a shiny silver edge screaming out to me. Turned out to be Canadian bicentennial. I think they were 80 percent silver. I know they aren't that unusual. I enjoy the hunt anyhow.
