1959 Mexican 20 Centavos (Copper Pyramid): Value & Prices

If you inherited or found a 1959 Mexican 20 centavos, here is the honest answer: worn examples are worth from a few cents to a couple of dollars. It is common copper-alloy, not silver. Only uncirculated coins with full original luster or genuine mint errors reach real money, and those are the exception.

This is the reddish-gold coin with a pyramid on the back, part of the "Pyramid series" struck at the Mexican Mint (Casa de Moneda de México) from 1955 to 1971. In 2026, it remains one of the most common Mexican coins people ask us about, and one of the most over-hyped by videos promising thousands. Let us set the record straight.

What it's worth in 2026

Value depends almost entirely on condition (what collectors call "grade") and whether the original mint luster is still there.

These are collector-market ranges, not offers. A dealer buying will pay less than the retail figure, and a very common date like 1959 gives you little leverage. To see what real buyers pay, compare listings in the Pesoteca shop directory before you accept the first number.

Is it silver? No

This is the question we get most, so let us kill the myth up front. The 1959 20 centavos is brass, an alloy of 95% copper and 5% zinc. There is no silver and no gold in it. That reddish-gold color that darkens over time is exactly what copper does. Because it holds no precious metal, it has no melt value floor the way a silver coin does. If you have older Mexican pieces, the ones that actually contain silver come from an earlier period; see our guide to the modern pre-1992 era for where this coin fits.

Is it rare? The mintage trap

The 1959 issue had a mintage of 6,017,000 coins, one of the lower figures in the 1955 to 1971 series. That single fact fuels a lot of "rare coin" claims, and it is misleading. A low mintage only matters if few coins survived. This one circulated for years and survived by the hundreds of thousands, sitting in drawers, jars, and collections across Mexico and the US. Common survival, not the mint figure, is what sets the price. So no, a worn 1959 20 centavos is not rare.

What actually raises the value

Two things move this coin above pocket-change money:

1. Uncirculated condition. A coin with full, unbroken mint luster and no wear is genuinely scarce because almost everyone spent theirs. This is where the real premium lives.
2. Genuine mint errors. Strong off-center strikes, dramatic doubling, or a wrong planchet can add value. The word is genuine. Most "errors" people see are post-mint damage, corrosion, or normal die wear. A real error needs a knowledgeable eye to confirm.

The viral videos promising thousands of dollars almost never describe the coin in your drawer. They describe a top-grade or true-error example that trades in a specialist market.

The details, so you can identify yours

• Weight: about 9.85 to 10 grams
• Diameter: 28.5 mm (large for the denomination, because 20 centavos was everyday money then)
• Edge: plain (smooth)
• Reverse: the pyramid of Teotihuacán in the center, the volcanoes Iztaccíhuatl and Popocatépetl behind it, a radiant Phrygian cap above with the value, the mint mark "Mo" below, and the word TEOTIHUACAN at the base of the pyramid
• Obverse: the Mexican coat of arms (eagle on a cactus with a serpent) and the legend ESTADOS UNIDOS MEXICANOS

How to tell if yours is genuine

Start with the physical specs. Weigh it: a real one lands near 9.85 to 10 grams. Measure it: 28.5 mm. Check that the edge is plain and that you can see the "Mo" mint mark under the Phrygian cap. The reverse should clearly show the Teotihuacán pyramid with both volcanoes. Red flags are a weight far off the mark, mushy or poorly defined lettering, and a reverse design that looks soft or wrong. Fakes of a low-value coin like this are uncommon, so most concerns turn out to be authentic but simply worn.

How to check what yours is worth and where to sell

Grade first, then sell. Compare your coin honestly against the condition table above. If it might be uncirculated or a possible error, get a second opinion before you assume a big number. For buying or selling, use the Pesoteca shop directory to find dealers who work with Mexican coins so you can compare offers instead of taking the first price. For a common coin, that comparison is the difference between a fair deal and giving it away.

Got a 1959 20 centavos that still has its shine, or something on the reverse that looks off-center? Post clear photos in the Pesoteca forum and let the community weigh in before you sell.

The centavo coins circulating in Mexico during the second half of the 20th century were struck in alloys that changed according to the cost of metals: copper, bronze, and brass in low denominations (1¢, 5¢, 20¢); cupronickel for intermediate denominations (25¢, 50¢, later 10¢); and .720 silver for some 25¢ and 50¢ pieces in the 1950s. Each change of alloy produced a distinct variant of the same face value. 1959 corresponds to the period in which this variant was in circulation, before the transition to Nuevos Pesos in 1992. The Mexico City Mint kept the basic design of the National Coat of Arms on the obverse and the numeric value on the reverse throughout this era.
