Best Answer

A standard roll of US half dollars contains 20 coins regardless of their metal composition. 40% silver halves weigh 11.5 gm each so a full roll would be 230 gm. Dividing that by 28.35 gm/oz gives a weight of 8.11 US ounces.

(5.67 grams per quarter x 40 quarters) divided by 453.592 grams per pound = 0.5 pounds

5.67 * 40 = 226.8

226.8 / 453.592 = 0.50000881849768073510996666607877

Math is fun.
