I just dug this up out of my front lawn. It is a 1920 Canadian penny. (Our house was built in the 20s.) I'd like to a] get an idea of any value it might have just for fun (it's likely worth <$1.00). I've looked on a couple of sites. Apaarently the 'DEI GRA' is significant. b] clean it up. I've tried Brasso, but little luck. I've tried peroxide but little luck. Next, I'm thinking of trying C-L-R. Any ideas? Coin collectors have any advice?
