No expert on Canadian coins but a quick google search says it is worth only face value. The one with the P is worth more.
You know I love to find ANY Canadian Coin when I'm coin roll hunting. I will concur with the rest of the group that it's only worth about face value. What is interesting is that the Canadian Mint no longer manufactures these. I keep all of the canadians I find merely as conversation pieces and if you find a very old canadian cent put it in a 2X2 and enjoy it for what it is! Take a trip up there and enjoy our neighbor to the north!
