Vietnam - 50 Xu 1953 3 Asian Graces

State of South Vietnam. This 50 Xu and the side portrait 20 Xu make a lovely pair depicting, what I assume is, women from three different ethnic or tribal groups. A rare theme that evokes the Three Graces of Roman antiquity. OB legend: "QUOC-GIA VIET-NAM". Made of an aluminum - magnesium alloy that was supposed to originate from scrapped aircraft, but I need to confirm this.
