These are Mexican silver(?) medals, every medal about 215 grams. I can't find any reference. Thanks in advance.
Don't know these, but yes, seems they are silver (Ag 999) with a diameter of 65 mm and a weight of 217.7 g (7 oz). That "Crossroads Mexico" series was made by the Mexican Mint (Casa de la Moneda de México) in 1992 according to this page. Christian
