A US quarter struck in 1964 or 1965 (dated 1965) and later weighs about 5.67 grams. A US quarter struck between 1930 and 1964 weighed 6.25 grams. This would make a roll of qâ¦uarters, or 40 quarters, weigh between 226.8 grams and 250 grams. This is about half a pound for the lower figure and almost 1 ounce more for the higher figure.
If the relationship was random the less valuable coins would be spent and the more valuable coins hoarded (Greshamâs Law). See the calculations below. Current copper-nickel clad dimes weigh 2.27 grams making 13.7 dimes to the troy ounce x 12 (the number of ounces in a troy pound) or 164.45 dimes to the troy pound. Face Value: $16.45. Current copper-nickel clad quarters weigh 5.67 grams or 5.485 to a troy ounce x 12 = 65.82 quarters to the troy pound. Face Value: $16.45.
