What is a Grain? Platinum weight, conversions and local use
Definition. The grain (0.0648 g) is the smallest troy unit, one 480th of a troy ounce. One grain equals 0.0648 grams, or 0.00208 troy ounces, which at today's platinum spot price works out to — AUD.
Where it is used. Historical coin weights, gold leaf and very small assay samples are still specified in grains. The unit is the trading standard in coin collecting and assaying.
Pricing conventions. No modern bullion product is sold by the grain, but numismatic catalogues use it, so collectors convert grain weights when valuing old coinage. Platinum has almost no traditional-unit retail market: it is quoted per ounce or per gram, and this conversion is mainly used for jewellery weighing and industrial stock.
Good to know. The grain was originally the weight of a single barley seed, making it one of the oldest surviving mass units in use.

Buying Platinum in Australia: local market, taxes and premiums
At the live price shown above per grain, the price you see here is the international XPT spot price converted into Australian Dollar. Physical buyers in Australia pay that reference plus a premium, and local trading is concentrated around Perth, home of the government-guaranteed Perth Mint. Buyers there generally watch the Perth Mint spot feed in AUD per ounce as the day's reference.
Taxes and duties. Silver must be 99.9% and platinum 99% to be GST-free; anything below those thresholds, including jewellery, attracts 10% GST. Platinum is a much smaller market driven by autocatalyst and jewellery demand, so local availability is patchier and dealer spreads wider. That is why the shop price of platinum in AUD can sit noticeably above the spot value of the same grain of metal.
How people usually buy. The common routes in Australia are Perth Mint depository, ABC Bullion and other national dealers, online dealers and ASX-listed metal ETFs. The products most often quoted locally include Perth Mint Kangaroo, Lunar series coins, 1 kg silver bars, unallocated depository accounts.
Local conventions. The Perth Mint's depository programme lets buyers hold allocated or unallocated metal without taking delivery. Before you buy, compare the dealer's asking price per grain with the live platinum price above, and check the buy-back spread the same dealer offers — that round-trip cost matters more than a small difference in the headline AUD quote.
