One of the newest traditions in the world of elite military units is that of the Challenge Coin. If at the bar and you can show your FBI challenge coin and the others can't, then they have to buy the drinks! These FBI challenge coins are cast in heavy bronze with deep relief. Each coin is just over 1 9/16-inches in diameter and weighs in at just over an ounce. Not only a fun way to get drinks at the bar, these coins are a great collectors item to obtain. If you don't have your FBI challenge coin now, then it is highly recommended you order yours today. don't wait or you'll be the one opening a tab at the bar.
