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.
1932-D and 1932-S quarters are among the most valuable of the non-error Washington silver quarters. The 1932-D and 1932-S can bring in $200 to $300 and up in higher-level circulated grades. However, most Washington silver quarters are worth between $3 to $4 each in typical worn grades. Be on the lookout, because Washington silver quarters still can pop up in circulation (although rarely). It is more likely that you will find one (or more) in rolls, collections, drawers, or an old jar of coins.
