HQVN token/medallion/souvenir (challenge coin?).
Hai-Quan Viet-Nam (Navy of Vietnam).
I've had this medallion since I was in Viet-Nam (1970/71). I believe it was cast in the foundry of the shipyard where I worked. Most of the large castings we made for plaques were aluminum whereas this "Challenge Coin" sized token is either brass or bronze. I carry it occasionally, but as it is nearly twice the weight of the challenge coin (below) it tends to be rather heavy in my pocket. I never called it a Challenge Coin because back then I'd never even heard the term.
