Why Buyers Choose Casa de Moneda de México

• The Americas’ oldest mint: founded in 1535 during the colonial era, the Casa de Moneda de México has nearly five centuries of continuous minting heritage — a history unmatched by any other mint in the Western Hemisphere.
• More gold per coin than any standard 1oz format: the Mexican 50 Peso Centenario contains 37.5g of fine gold (~1.2 troy ounces), approximately 20% more gold than a 1oz Britannia or Krugerrand.
• Iconic Winged Victory design: the Centenario features the Angel of Independence — one of Mexico City’s most famous monuments — creating one of the most distinctive and recognisable designs in the historic coin market.
• Dual bullion and collector appeal: the coin’s substantial gold content, historic origin, and design character attract both bullion buyers and collectors, supporting demand beyond pure spot-price valuation.

Casa de Moneda Products Available

The Casa de Moneda’s flagship product for UK bullion buyers is the Mexican 50 Peso Gold Coin (Centenario) — originally struck in 1921 to commemorate the centenary of Mexican independence, with restrike production continuing to meet international bullion demand. Each coin contains 37.5g of fine gold in a 900 fineness (21.6 carat) alloy, with a gross weight of approximately 41.67g.

If you are comparing the 50 Peso against other large gold coins, the key comparisons are the $20 Double Eagle Liberty (~30.09g fine gold), standard 1oz coins like the 1oz Britannia (31.1g), and the Krugerrand (31.1g). For smaller historic coins in a similar format, compare with French 20 Franc and Swiss 20 Franc coins. Our best gold coins guide helps you compare across all major coin families.

How to Compare Casa de Moneda Coins

When comparing Casa de Moneda products with coins from other mints, UK buyers typically look at total gold content per coin, premium over the live spot price, historic and collector value versus pure bullion value, tax treatment versus UK legal-tender coins, and resale familiarity in the UK and international secondary markets. Mexican coins are not UK legal tender, so the CGT discussion differs from Britannias and Sovereigns. For the latest tax position, check the HMRC guidance on investment gold and VAT and the HMRC CGT manual.
