The 2006 Canadian Cents you want to watch for are:
2006P Non Magnetic - Rarest
2006 No P No ML (Maple Leaf Logo) Magnetic
Some people consider the 2006 No P No ML rarer then the 2006P Magnetic. For my findings so far (On box 103) I have found 4 x 2006P Magnetic, 9 x 2006 No P No ML Magnetic and 0 x 2006P Non Magnetic.
Others have different find ratios I imagine.
