From now on, thoughts will cost a nickel

A box full of shiny pennies at Northgate Stamp and Coin in Edmonton, May 4, 2012. The last penny was struck Friday at the Canadian Mint because it is being eliminated. Pennies aren't worth much. Even a 1859 one only goes for a few dollars. The exception is a 1936 Canadian penny with a raised dot under the date fetches around $360,000 to $400,000.
