U.S. Silver Quarter Melt Value Calculator. The U.S. Silver Quarter Melt Value Calculator, shown below, will help you find the total silver value and total silver content of your U.S. Barber, Standing Liberty, or Washington 90% junk silver quarters. Calculate by quantity, rolls of quarters, face value or weight. The silver quarter calculator will only figure what the silver in your quarters is worth (intrinsic value), and will not include any numismatic (collector) or base metal value.
Early on, the silver coins had different percentages of silver than what we know of today. The half dime, which as the 5 cent coin of that period, contained 89.24% silver. The first dimes, quarters, half dollars and dollar coins of the time also contained 89.24% silver. This seemingly odd percentage of silver continued for these coins until 1837 for dimes, 1838 for quarters, 1836 for half dollars and 1837 for silver dollar coins. The change was mandated by The Law of January 18, 1837 to 412 1/2 grains in weight and .900 fineness.
