Each 100 Gram Perth Mint Gold Bar has been produced with 100 grams of .9999 pure gold. This superior level of refining is uncommon in the gold bullion industry and is further evidence of the mints continued excellence. Each bar is stamped with the Perths logo, which features its telltale swan. Each bar is also inscribed with its weight and gold purity. The opposite side of every bar features a repeating pattern of hopping kangaroos, a symbol of Australias wildlife heritage.
