My second job is at a grocery store and today while counting change, I found two quarters that were different, one was a 1954 silver quarter and the other was 2006 state of Nevada quarter that looked like a Canadian quarter when I saw it in the roll, it has the same silver color rim as the Canadian steel coins and not anything like the silver us coinsIt is not magnetic nor does it sound like the silver coins unless it is from a proof set but with less silver. It could just be a strange clad dye that looks steel. Probably worth a quarter, but interresting.
