1 Dollar - Elizabeth II 6th Portrait - Quokka - Silver Bullion Coin

The quokka, native almost exclusively to Rottnest Island off the Western Australian coast, was named by Dutch explorer Willem de Vlamingh in 1696 — he mistook the animals for large rats, giving the island its name ("Rottnest" from Dutch for "rat nest"). Perth Mint has leaned heavily into Australia's endemic fauna for its bullion series, and the quokka's selection reflects both the animal's geographic proximity to the Perth facility and its surge in international recognition driven largely by tourist selfie culture in the 2010s. The .9999 fineness places it among the purest silver bullion issues Perth produces.
