Navy Gunner's Mate Challenge Coin "Grab Your Helmet"

Description

This coin embodies the dark humor of the Navy's Gunner's Mate. Generally brash and unapologetic, the GM is the back bone of the Navy's warships. Without the GM, the ships might as well be cruise ships. Show your appreciation for the GM and add one of these to your collection.
The Challenge coin is roughly the size of a US Silver dollar as shown in the picture.
