Challenge Coins Done Right! What better way to thank a Soldier than a challenge coin in an Artillery Shell? They will double as a Whiskey Stash or a Piggy Bank. These two are spoken for but if you've got a coin we can probably fit it in a round from 75mm all the way to 8 inch. We've got mortars, artillery and tank shells and a few rockets. See what's in store.. Follow the Profile link. Follow along, more is on the way.
