What is a Momme? Platinum weight, conversions and local use
Definition. The momme (3.75 g) is the traditional Japanese unit of mass, best known for pearls but also used for precious metals. Locally it is written 匁. One momme equals 3.75 grams, or 0.12057 troy ounces, which at today's platinum spot price works out to — USD.
Where it is used. Japanese jewellers and pearl dealers quote per momme, and it is the unit behind many antique Japanese silver weights. The unit is the trading standard in Japan.
Pricing conventions. Japanese bullion dealers publish tax-inclusive yen prices per gram, so a momme quote is usually a conversion rather than the headline rate. 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. One momme equals one tenth of a Taiwanese tael and matches the Korean don exactly.

Buying Platinum in United States: local market, taxes and premiums
At the live price shown above per momme, the price you see here is the international XPT spot price converted into US Dollar. Physical buyers in United States pay that reference plus a premium, and local trading is concentrated around New York and the large national online dealers. Buyers there generally watch the COMEX front-month contract and the LBMA PM auction as the day's reference.
Taxes and duties. Silver, platinum and palladium follow the same state-level rules, and long-term gains on physical metal are taxed as collectibles at up to 28%. 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 USD can sit noticeably above the spot value of the same momme of metal.
How people usually buy. The common routes in United States are APMEX-style online dealers, local coin shops, US Mint authorised purchasers and COMEX futures and ETFs. The products most often quoted locally include American Gold Eagle, American Buffalo, 1 oz Silver Eagle, 10 oz and 1 kg bars.
Local conventions. Prices are quoted per troy ounce; jewellery is sold in karats (14K and 18K dominate) rather than fineness. Before you buy, compare the dealer's asking price per momme 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 USD quote.
