30 Dollars - Elizabeth II Bottlenose Dolphin - Gold

Perth Mint's 1/3 oz gold bullion series occupies an awkward commercial niche — too heavy for entry-level buyers, too light for serious stackers — which is precisely why the bottlenose dolphin issues from this period moved predominantly into the Asian gift and collectible market rather than the Western bullion trade. Perth's marketing pivot toward Chinese retail buyers in the mid-2010s drove a sustained run of wildlife-themed fractional gold that kept the mint's refinery operating at near-capacity through 2019.
