Investing in Physical Gold and Silver from Mexico: The Real Guide (2026)

Gold and silver are back in the conversation in 2026. Silver climbed more than 26% in two weeks, and the Mexican gold Centenario now trades around 4,700 to 5,000 US dollars per coin. If you are thinking about putting money into physical metal, this is what a seasoned collector would tell you before you spend a single dollar: how it works, the tax advantage almost nobody explains correctly, and the three places where people lose money without noticing.

You will not read "buy now, it's going up" here. You will read how to buy without getting fleeced.

Should you put money into physical metal?

Gold and silver work differently from a yield investment. They do not pay interest and they do not pay a dividend. What they do is store value: when a currency weakens or the economy gets nervous, metal tends to hold up. That is why it is called a safe-haven asset, not a growth asset.

That has a practical consequence worth understanding from the start. Physical metal is for holding, not for weekend trading. If your plan is to buy today and sell in three months chasing a quick gain, physical metal will almost always disappoint you, because the gap between what you pay and what you get back when you sell eats any short move (we will show you this with numbers below).

The right question is not "will it go up?" Nobody knows, and anyone who swears they do is selling something. The right question is "do I want part of my savings in something physical, outside the bank, that has historically held up against inflation?" If the answer is yes, keep reading.

Gold or silver: which one fits your budget

The first decision is not about taste, it is about budget. The two metals most people buy through official coins from Banco de México (the country's central bank) are the Centenario (gold) and the Onza Libertad (silver). They sit in completely different price leagues.

The Centenario is a 50-peso gold coin containing 37.5 grams of pure gold, first struck in 1921. The Onza Libertad is a one-troy-ounce silver coin of .999 fineness, weighing 31.1 grams. Both are official Mexican bullion, and both carry the same tax advantage explained below.

	Centenario (gold)	Onza Libertad (silver)
Price today (USD)	~4,700 to 5,000	~62 to 74
Metal	37.5 g pure gold	31.1 g silver .999
Entry cost	High, full coin at once	Low, build up gradually
Best for	Someone protecting existing capital	Someone starting and stacking slowly

Prices move every day with the international spot price and the exchange rate. You can see the live per-bank breakdown at Centenario price today and Onza Libertad price.

The logic is simple. If you have several thousand dollars sitting idle and want to protect it, one Centenario converts it into gold in a single move. If you have a smaller amount each month and want to start, the Onza Libertad is the cheapest entry point into precious metals, and you can accumulate one at a time without feeling the hit.

The tax advantage almost nobody explains: no sales tax

This is the point sellers mention halfway and that is worth understanding in full, because it is a real advantage.

In Mexico, investment gold and silver are exempt from IVA, the value-added sales tax (16%). The IVA law leaves gold and silver coins and pieces denominated in troy ounces outside the tax, along with gold bullion above a minimum fineness. That is why an Onza Libertad or a Centenario bought as an investment does not add that 16% on top.

The reason behind it is that Mexico does not want to lose competitiveness against the international metals market, and Banco de México holds gold reserves that back the currency. This is not a loophole or a trick, it is deliberate tax policy, the same approach used by the European Union and the United Kingdom.

The fine print: the exemption applies to metal bought as an investment. The moment the same piece is sold as jewelry or as a collector item with a markup, the situation changes. As long as you buy the investment coin through a formal channel (a bank, the national Mint, a serious dealer), you are on the exempt side.

Physical gold vs safe savings instruments vs the dollar

The real comparison is not "metal good, bank bad." Each option does something different, and smart savers spread out. Here they are side by side. Cetes are short-term government treasury certificates, Mexico's equivalent of US Treasury bills, and accessible from about 5 dollars.

	Physical gold/silver	Government T-bills (Cetes)	US dollar
What it does	Stores value, safe haven	Pays a fixed yield	Exchange-rate hedge
Minimum entry	One Onza (~65 USD)	From ~5 USD	Whatever you buy
Yield	Pays no interest	Yes, known rate	No, depends on exchange rate
Liquidity	Medium (selling takes effort)	High at maturity	High
Sales tax	Exempt	Not applicable	Not applicable
Risk	Volatile, metal price	Low, state-backed	Volatile, exchange rate

Government T-bills give you something metal does not: a yield you know in advance, backed by the state, with a tiny entry point. If your goal is to make your money work with certainty, T-bills win outright.

Metal plays a different game. It is the physical thing you can keep at home outside the banking system, the thing that does not depend on a platform staying online. Its appeal is not yield, it is backing. That is why the advice experienced holders repeat is not to put everything in one place: part in instruments that pay, a small part in metal as a reserve.

The three places where people lose money

This is where we separate the buyer who buys well from the one who overpays. These are the three holes money slips through, and the person selling to you will not warn you about any of them.

The premium: you don't pay spot, you pay more

The price of metal on the international market is called spot. But nobody sells you an Onza at bare spot. They add a premium, running from 8 to 15% depending on the seller and the year. That premium covers minting, distribution, and the seller's margin. It is normal for it to exist. What is not normal is paying a 30% premium because you did not compare.

The rule: to invest, look for a current-year piece in brand-new condition, which is the one you can get closest to spot. The less premium you pay going in, the less the metal has to rise before you start to gain.

The loss when you sell fast

This is the one that hurts most. When you want to sell, the bank or exchange does not pay you what they charged you. They pay less, typically 10 to 15% below the sale price. That gap between what you buy at and what you get back is the real cost of getting in and out.

That is why physical metal is not for the short term. If you buy a Centenario and want to sell it next month, you start out down that 10 to 15% even if gold has not moved a cent. Metal rewards the holder, not the trader.

Fakes

Where there is valuable metal, someone imitates it. Fake Onzas, restruck Centenarios sold as originals, silver that is not really .999. Buying at a bank or the national Mint protects you from this. Buying from a stranger in an unverified group does not.

Before you hand over money in the informal market, learn to tell the real thing from the doctored one. We have two guides for that: how to spot a fake Onza Libertad and original Centenario vs restrikes. Read them before buying from anyone outside a formal channel.

Where to buy without getting fleeced

The formal channels are the national Mint (Casa de Moneda de México), authorized banks (several sell the Centenario and the Onza), and serious dealers. You pay a premium there, yes, but you get an authenticity guarantee and you avoid all three holes above.

Sale prices change every day. Before you buy, check what each bank is charging today so you do not overpay: the full, updated breakdown is at Centenario price today and Onza Libertad price.

If you have already decided where to start, we have the deep dive on each one: is the gold Centenario worth investing in? for gold, and is the Onza Libertad worth it? for silver. Those get into which year to buy and how not to overpay on premium.
