A member from my local Star Wars club hooked me up with this beauty of a coin. It's the 501st Legion Bloodfin Garrison challenge coin. For those not familiar with the challenge coin let me give you a brief summary.
In the military, supposedly the Army Air Corps of WWII

The tradition is still alive today and an example as to how it is often used is that a member of an organization would pull his coin out and challenge a fellow member. If the fellow member failed to show his challenge coin then the loser of the challenge would but him a drink. If the challenged produced his coin then the challenger made his request then the challenger would have to buy him a drink.
p.s. Dont ever drop yours.
