What is a Grain? Gold 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 gold spot price works out to — MXN.
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. Gold is the metal most often traded in these traditional units, because jewellery and savings demand kept the old weights alive long after industry went metric.
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 Gold in Mexico: local market, taxes and premiums
At the live price shown above per grain, the price you see here is the international XAU spot price converted into Mexican Peso. Physical buyers in Mexico pay that reference plus a premium, and local trading is concentrated around Mexico City and the Banco de México coin programme. Buyers there generally watch the Banco de México reference price and the peso-dollar rate as the day's reference.
Taxes and duties. Sales of Centenario and Libertad bullion coins by banks are generally IVA-exempt; bars and other formats can attract 16% IVA. Gold is the deepest of the four precious metals markets, so local retail spreads are usually the tightest and buy-back is easiest. That is why the shop price of gold in MXN can sit noticeably above the spot value of the same grain of metal.
How people usually buy. The common routes in Mexico are Banco de México and commercial banks, Casa de Moneda distributors, coin dealers and online dealers. The products most often quoted locally include Centenario 50 pesos, Libertad gold and silver, 1 oz bars.
Local conventions. The 37.5 g Centenario and the Libertad series are the traditional local savings instruments, quoted in pesos per piece. Before you buy, compare the dealer's asking price per grain with the live gold 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 MXN quote.
