Here is a unique coin from a GC forums regular. There was an annoying rollover on the website so I could only get the back, but the front has a very angry bear that apparently bit the coin. The bear looks like that half polar/half grizzly that was in the news not long ago :) You might be able to reserve one from White Bear here.
Here's what Landsharkz says about it:
Bitten by Whitebear
500 minted (various finishes including the coolest ever glow in the dark!)
Trackable with WB prefix and icon Coming up... mid November 2006
1 1/2" diameter, 3mm thick, $8.00 + shipping W/WB prefix.
Will be available from landsharkz.ca AND directly from Whitebear. You can see it for your self here.
