How we compare prices (Methodology)
  • Data sources: We fetch live pricing from participating dealer product pages and/or APIs.
  • Refresh cadence: Prices and spot updates sync on a schedule (typically every hour). Each page shows a timestamp when the prices were last refreshed.
  • Payment normalization: Rankings default to bank/ACH pricing. Where dealers publish multiple payment prices, you should verify the price on the dealer website based on the selected payment method.
  • All-in price: Due to differences in sales tax, shipping costs and payment method adjustment, we show item price and note what’s included.
  • Premium over spot: Premium = The amount charged by the dealer, minus the current spot per unit for this specific product.
  • Stock handling: Typically, we only show prices if the dealer has the item available for sale on their website. Pre-Orders are typically labeled. Sometimes, dealers will list items as in-stock and available for sale when they are on backorder; out-of-stock offers are de-prioritized or hidden.
  • Independence & disclosure: Dealers cannot pay to change rankings. Some outbound links are affiliate/sponsored; they’re marked and use rel="sponsored". This does not affect how prices are displayed.
  • Corrections: See something off? Contact us and we will do our best to fix the issue quickly.

Expert Notes

The 100 Pesos Mexican Silver Coin (1977-1979) offers U.S. silver investors a practical way to add historic Mexican silver to a stack at a competitive premium.

Background

Founded in 1535, La Casa de Moneda de México has shaped the global history of coinage for centuries. The 100 Pesos Mexican Silver Coin (1977-1979) arrived during Mexico’s final phase of silver-based circulating currency. Its .720 silver content balanced intrinsic value and durability for everyday use, while the Hidalgo portrait honored the nation’s independence movement. Today, these coins typically appear in circulated grades, though uncirculated examples and attractive toning bring added numismatic interest. Because the coin’s ASW is clearly understood and the fineness is marked on the reverse, buyers can compare premiums across dealers with confidence and choose the best price per ounce of silver.

Note: Precious metals can fluctuate in value. Consider your budget, time horizon, and risk tolerance, and compare multiple offers before you buy.
