Not suprisingly, we do not have a Gamma Phi Beta challenge coin. The idea of a bunch of my elderly "senior sisters" throwing down a coin at a bar is kind of comical.
I have, however, been awarded two US Army challenge coins for my work with ROTC. I don't have one from my roommates' [USMC] squadron; but, you'd like it Jon. It's black and has a big skull and crossbones on it.
I'm proud of military coins (they are not cheap pieces of crap; one is gold plated) and have them on display. If I was a guy, I might appreciate receiving my fraternity coin as a token for service to the chapter or fraternity programming...but I'm not sure about just picking one up for $14.95. When it's given to you, it means something.
