answered question 12/31/2009 What Are These Worth? 1968 Mexico 25 Pesos Olympic Coin Type 1 And 2 My 4 pieces weight 22.36 + 22.36 + 22.49 + 22.53 of .720 Silver or over 16 grams. PURE Silver at $17.00 makes them approx. $8.80 USD "Melt" per coin. They are also 40 years old and mark the 19th Olympics. Better is More costly.
