Mexican 20 Pesos Navy Bicentennial Coin (2022): Value & Facts

If you found a large two-tone Mexican 20 Pesos coin showing sailors and a ship, here is the honest answer: it is worth about face value, roughly 1 to 1.50 USD, unless it is in pristine uncirculated condition. This is the 20 Pesos Bicentenario de la Marina-Armada de México, a commemorative coin the Bank of Mexico released in 2026 circulation history, and it is not rare.

What this coin actually is

This is a circulating commemorative issued by Banco de México (Banxico, Mexico's central bank) to mark 200 years of the Mexican Navy. "Bicentenario de la Marina-Armada de México" translates to "Bicentennial of the Mexican Navy." It is a bimetallic coin: a bronze-aluminum outer ring around a copper-nickel center, the same construction as a US dollar coin but with two colors.

Here are the exact specs, straight from Banxico:

• Denomination: 20 pesos
• Weight: 12.67 grams
• Diameter: 30 mm
• Composition: bronze-aluminum ring, copper-nickel center (no silver, no gold)
• Official mintage: 5,000,000 pieces
• Family: C1 series

That mintage number is the key to the value question. Five million coins is a large run. There is nothing scarce here, so anyone quoting you hundreds or thousands of dollars is inflating the price.

How much is it worth in USD?

Condition	Approx. value (MXN)	Approx. value (USD)
Circulated (worn, from change)	~25 pesos (face value)	~1.30 USD
Uncirculated, loose, bright	up to 90 pesos	~4.50 USD
Sealed Banxico blister pack	above loose UNC	~5 USD or slightly more

The reference price of 90 pesos in top uncirculated grade comes from validated sales tracked in the Pesoteca catalog. Values shift with the peso-dollar exchange rate, so treat the USD figures as a ballpark. The takeaway does not change: this is a low-value modern coin. Its worth is driven by condition, not rarity.

Why the coin says 1821 and 2021 but circulated in 2022

The dates 1821 and 2021 stamped on the coin mark the bicentennial: the Mexican Navy was founded in 1821. The coin design carries those anniversary dates, but Banxico did not put it into circulation until October 4, 2026 timeline reference (originally 2022). There is no separate "2021 version" and no separate "2022 version." It is one coin. If a seller claims a rare date variant, they are wrong.

Who is on the coin

The reverse features Lieutenant José Antonio de Medina Miranda in the center, flanked by the schooner Iguala on the left and a modern Long-Range Ocean Patrol vessel below, linking the Navy of 1821 to today's fleet. The obverse carries Mexico's national coat of arms, the eagle and serpent, as on all Mexican coins.

Are there valuable minting errors?

Genuine mint errors (off-center strikes, die rotation, double strikes) can multiply a coin's value if verified. But be realistic: most "errors" people post online are post-mint damage, dents, scratches, and corrosion, not factory mistakes. Those add nothing. If you think you have a true error, get it looked at before you get your hopes up.

Related commemoratives to check

If you have a box of these two-tone 20 peso coins, others in the same C1 family are worth a quick look:

• 100 Years of Mennonite Arrival in Mexico (2022)
• Centennial of the Death of General Emiliano Zapata (2021)

None of these are rare either, but condition and sealed packaging can nudge the price up.

How to check what yours is worth

1. Verify it's genuine. Weigh it on a jewelry scale (should be 12.67 g) and measure the diameter (30 mm) with calipers. Fakes usually miss on weight or diameter, or show flat relief and mismatched colors.
2. Grade the condition. Circulated with wear equals face value. Sharp, bright, no spots equals uncirculated and the higher end.
3. Compare before you sell. Photograph the obverse, reverse, and edge, and match against the reference range above.

Where to sell it

For selling, a verified coin shop from the Pesoteca dealer directory will appraise it on the spot without a markup middleman. Collectors also trade directly in the Pesoteca buy-sell forum. Skip dumping it on Facebook to the first buyer, and check the price range on this page first so you know what a fair offer looks like.

This coin celebrates the 200 years of the Navy of Mexico, an institution born almost at the same time as the country. On October 4, 1821, just after the Act of Independence was signed, the Regency headed by Agustín de Iturbide created the Secretariat of War and Navy, and placed Lieutenant Antonio de Medina Miranda at the head of the naval branch. Thus began the history of a navy of its own, pressed to defend an enormous coastline and a still-fragile sovereignty.

The biggest unfinished business was in plain sight from the port of Veracruz: the fortress of San Juan de Ulúa, the last Spanish stronghold on Mexican soil, which refused to recognize independence. The naval blockade commanded by Pedro Sainz de Baranda forced its surrender on November 23, 1825, and with that national independence was consolidated. That is the feat this piece recalls.

The Bank of Mexico put the coin into circulation on October 4, 2022, as part of the bicentennial (the reverse legend marks 1821-2021).

How to read the reverse and identify it

It belongs to the commemorative 20-peso series, bimetallic and dodecagonal (12-sided), 30 mm in diameter, 12.67 g, with a continuous reeded edge and mint mark M. Where you recognize it is on the reverse: at center, the bust of Lieutenant José Antonio de Medina Miranda; on the left, the schooner Iguala; below the figure, a Long-Range Ocean Patrol vessel — that is, the Navy of yesterday and of today on the same face. On the right runs a microtext reading TTE NAV ANTONIO DE MEDINA MIRANDA (readable with a loupe; to the naked eye it looks like a line) and on the left an anchor as a latent image that shifts with the angle of light, a security element and a good sign that the piece is genuine. In the exergue is the denomination $20 flanked by the years 1821 and 2021. Those dates mark the bicentennial of the Navy (founded in 1821), even though the coin went into circulation on October 4, 2022; the die reads 2021, not 2022. There is no "Navy 2019" or "Navy 2023": it's a single year on the die.

What it's really worth

This coin circulated normally and is not scarce; it's one of the common ones from the modern series, the kind you can still hunt without overpaying.

Condition	Reference (MXN)
Circulated (used, with scuffs)	near its face value, 25
Uncirculated (UNC, with luster)	up to 90

The difference between those two numbers is one thing: condition. A circulated one with scratches and lost luster is worth little more than its 20 pesos of spending value; a brand-new one, spotless and with factory luster, reaches the top of the range, and in an official Banxico blister better still for whoever is building the series. If a seller wants to unload it on you for hundreds or thousands "because it's historic and no longer available," that's a middleman: it is available, and the real range is the one in the table. To buy or sell at a fair price, check the store directory instead of marketplaces where they inflate the price.
