As an American who has since immigrated to Canada, I can verify that Canadian coins are almost identical in color, shape, weight, and with the recent economic downturn in the States, value, to American coins. With the notable exception of the Canadian $2 coin, which denomination only exists as a paper bill in American currency.
Having said that, I found out something interesting about Canadian coinage. Past a certain date, (haven't narrowed it down yet but I think it was the late 80's or early 90's) the Canadian mint that produces coinage changed the metals used to various forms of iron alloys. Coins older than a certain year don't stick to magnets, while newer coins do. Last time I checked, no American coins will stick to a magnet.
And living in a border city, (Victoria, BC) I can also verify that we see almost as much American coinage as Canadian, due to a large influx of American tourists who don't bother to exchange their coins with their paper currency. As such, I tend to accumulate a large pile of both. Easy way to separate it out? Yep. Magnets.
What does this have to do with this episode of the Daily Drop? Nothing. But it was indeed shiny.
