Centenario, Onza Libertad and investment metals · 2026
Putting your money into physical gold and silver in Mexico is done, above all, with two official Banxico pieces: the 50-peso gold Centenario and the silver Onza Libertad. Neither pays VAT when bought as an investment, both are sold by banks and the Mint (Casa de Moneda), and they exist to store value, not for weekend trading. Here you'll find the investment pieces with their real price of the day, the tax advantage almost no one explains, and the three places where people lose money without realizing it. If you're just starting out, read the full guide to investing in metals.

As a long-term reserve, yes: gold and silver hold their value when the peso weakens, and they pay no VAT when bought as an investment. The Centenario ($90,000 MXN) shields a block of capital in one move; the Onza Libertad ($1,300 MXN) is the cheapest way in to build up little by little. They don't work for the short term: when you sell, you're paid 10 to 15% below. The sensible approach is to hold a small slice of your wealth in metal, not all of it.
The formal channels are the Mexican Mint (Casa de Moneda), authorized banks and reputable dealers. You pay a premium, yes, but you get an authenticity guarantee. Before buying, check the price of the day by bank at Centenario price today and Onza Libertad price so you don't overpay.
To sell, the bank or exchange house buys from you below the selling price (10-15% less): that's the cost of getting out. That's why metal is a long-term play. Document your piece and compare offers before accepting. If it's a scarce-year piece or in collector condition, it may be worth more on its numismatic side: ask in the forum.
No, when bought as an investment. Mexico's VAT Law exempts gold and silver coins and pieces denominated in the troy ounce, along with gold bullion of minimum fineness. That's why an Onza Libertad or an investment Centenario doesn't add the 16%. The fine print: the exemption is for investment metal, not for jewelry or pieces sold at a collector markup.
It depends on your budget. Gold (the Centenario, ~$90,000 MXN a piece) shields a block of capital in one move. Silver (the Onza Libertad, ~$1,300 MXN) is the cheapest door in: you can add one every month without feeling the hit. For the cost of one Centenario you can gather more than 60 Onzas. Neither pays VAT as an investment.
The price changes every day with spot and the exchange rate, and it varies by bank. Check the updated breakdown at Centenario price today and Onza Libertad price. Compare across banks before you buy: the gap between the cheapest and the most expensive is real money.
They do different jobs. Cetes (Mexican treasury bills) pay a known fixed rate, backed by the State, and you can start with a hundred pesos: they win when you want certainty. Physical metal pays no interest; it stores value as a refuge outside the banking system. The sensible move is to split: part in instruments that pay, and a small part in metal as a reserve.
Because the bank buys it back below what it sold it to you for, typically 10 to 15% less. That gap between buy and sell is the cost of getting in and out. If you buy today and sell next month, you start out at a loss even if the metal hasn't moved. Metal rewards those who hold, not the short-term trader.
Buy through formal channels: the Mint (Casa de Moneda), authorized banks and reputable dealers. There you pay a normal premium (8-15% over spot) with an authenticity guarantee. Before buying on the informal market, learn to tell the real thing apart: fake Onza Libertad and original Centenario vs. restrikes.
El oro y la plata volvieron en 2026. Cómo se compra metal físico sin que te vean la cara: la ventaja del IVA, oro vs plata vs Cetes, y los tres lugares donde la gente pierde dinero.
Mi tía compró un Centenario en Banamex en 1987 por algo así como cinco mil pesos. Hoy anda arriba de 80 mil. Cada vez que se lo recuerdo, me mira como si le tomara el pelo. Esto es lo que tienes que saber antes de comprar o vender uno.
El Centenario es la pieza de oro más conocida de México. Cuánto cuesta hoy por banco, por qué funciona como refugio, cuándo NO conviene, y cómo se compara con Cetes.
