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.
First estimate. A 5 gallon jug with just silver change (mostly quarters), and the total was 3500 dollars., so one filled with just quarters would probably hold around 5000 dollars or 20,000 quarters.Second Estimate.n one test with a 5-gallon plastic water jug, it held $5200 in quarters and weighed 260 pounds (80 quarters or 20 dollars to the pound).
