1 oz Silver Random Year Coin - Mexico Mint - .925 Ag

The coin mint called "de balancín" (of sway), was used in Mexico Mint to make their first coins. This device uses the rotation of a pole on top with weight on a side to get enough speed to force a spiral down and mint the coin (later updated to use steam and then electric motor but the method was the same).

Some people think that these rounds contain more than one troy ounce of silver and are led to believe that they have scored two and a half extra grams of silver for free. The reason that these metallic pieces weigh 33.625 grams (instead of one troy ounce, 31.103 grams) is that the silver alloy used in them is, unusually, only .925 pure. 33.625 grams multiplied by .925 purity = 31.103 grams of pure silver.
