how many grains of silver in one ounce
I think you mean 1000 gram ingots, not grains. That would be 100,000 grams of silver, or 3,215.07 troy ounces (oz t) in silver mass. Silver, gold and precious metals are always weighed in Troy ounces, which are different from the ordinary ounce.
14 silver dimes equal just a little more than 1 troy oz. Each coin has .07234 oz of pure silver.
1,500 grains is 3.42857 oz. Sterling silver is only 92.5% pure silver, so the actual silver content of 1,500 grains of sterling silver is 3.17143 oz (at about $18.50/oz = $58).
