OK, Thanks for taking a look. This is a 1968 Mexico City Olympic Games Commemorative Silver Bullion Coin, 25 Pesos face value.
Mint: Casa de Moneda, Mexico. Look for the mint mark in the lower right of the reverse.
Diameter: 38 mm
Weight: 22.42 grams
Actual Silver Weight: 16.14 grams = .52 Troy Ounces, more than 1/2 Troy Ounce of pure silver.
Fineness: 72% Silver. Look for the LEY 0.720 on the lower right field of the reverse, above the mint mark.
Obverse: An Aztec ballplayer, ball in hand, superimposed over a top view outline of an ancient Mesoamerican ballcourt (Those who have described this image as that of an "Aztec Dancer" have simply not done their homework!); JUEGOS DE LA XIX OLIMPIADA MEXICO 1968; and the Olympic rings.
Reverse: The Mexican Coat of Arms, an eagle on a nopal cactus with a snake in its beak; ESTADOS UNIDOS MEXICANOS; 25 PESOS; LEY 0.720; and the Casa de Moneda mint mark.
Condition: Circulated. Some minor surface marks. Some mild toning. The scanned images make the coin appear greyish, but it is actually a nice silver color. The coin in the images above is the exact coin you will receive, so please judge for yourself.
Fun Facts: Casa de Moneda is the oldest mint in The Americas. The 1968 Mexico City Olympics were the first held in a developing country, and the first held in a Spanish speaking country.
This is a real nice coin. Solid and heavy in your hand. A great piece of Mexican silver. And like most Mexican bullion issues, its silver content is listed on the face of the coin. We like that!
Lets do the math!
.72 Fineness x 22.42 grams = 16.14 grams pure silver
16.14 grams pure silver / 31.10 grams per Troy Ounce = .52 Troy Ounce pure silver
