Sources for pricing include actual transactions, public auctions, fixed price lists and any additional information acquired by the Mexican Coin Values valuing analyst. (Note: Dealer buy prices are wholesale valuations. Published buy prices in no way guarantee that a particular dealer will buy a coin at published buy price. Therefore, certain coins in this valuing section, especially some of the esoteric items, may differ greatly from advertised buy prices, both higher and lower.)
Market conditions, supply, demand and rarity are key considerations. Values are listed for coins that are strictly graded in each grade category according to the current market standard. Cleaned, whizzed, damaged or otherwise altered coins bring less value than posted in Mexican Coin Values listings.
