Grenade Coin

I had a golf scramble coming up and someone mentioned some fun additions to the game, grenade being one of them. A grenade is used usually when you hit the ball in the woods. You are then allowed to use it to throw the ball with your hand. The question came how do we know who actually paid for a grenade? So I made these quick little tokens to give to the paying players as proof, since in a golf scramble there is hardly any trust as it is.
