What is Australias rarest medal?
It is a toss up between the Military Medal (MM) with 3 bars awarded to Pte Corey in WW1 or the Albert Medal in Gold awarded to Sgt Coyne in WW1. Both are unique as the only one of their type ever awarded to an Aussie. The MM and 3 bars probably wins out because it is the only combination of that sort ever awarded to anyone.
