    OK, lets do some math.

    The total weight of the silver clad Kennedy is 11.5 grams. 40% of 11.5 is 4.6 and there are twenty coins in a roll of halves. 4.6 X 20 = 92. 92 grams of silver in a roll of 40% silver halves.

    Now there are 28 grams in an ounce so, 92 / 28 = 3.2857 or 3.3 ounces.

    And there you have it!!!

    There is one problem with your calculations - silver is referenced in Troy ounces. 31.1 grams to the Troy ounce. Therefore, there are 2.958 Troy ounces to the roll.
