Does anyone out there have a DDG 21 challenge coin for sale? I have the cash but not much of it!

OK Dave, I bite....

What is a challenge coin?

Maybe a Primo beer label patch?

Merry Christmas to all of you from 66-69.

It was a helluva lot of fun, never to be repeated.

Horace,
It is a coin, usually of a military genre, about the size of a silver dollar. When someone puts his coin out on the bar, he is challenging others to show  theirs. If you don't have yours on you, it costs you a drink. If everyone has one, the challenger buys drinks for everybody else.
I sawone on ebay but like a fool, I let itn get away!!!! >
