Answer
Each 90% silver dime holds about 0.0723 troy ounces of pure silver and each 90% quarter about 0.1808. Multiply the troy ounces by the silver spot price you enter to get melt value. A dollar of face value in 90% dimes, quarters or half dollars holds about 0.7234 troy ounces.
Worked example
Spot price $30.00 per troy ounce (an example, not a quote). 10 dimes: 10 x 2.5 g x 0.90 = 22.5 g = 0.7234 oz. 4 quarters: 4 x 6.25 g x 0.90 = 22.5 g = 0.7234 oz. Total 1.4468 oz of silver x $30.00 = $43.40 melt value on $2.00 of face value.
How it works
Pure silver = coin mass x silver fraction / 31.1034768 g per troy ounce. Masses and compositions: 90% dime 2.5 g, 90% quarter 6.25 g, Franklin and 1964 Kennedy half dollars 12.5 g (90%), Kennedy half dollars 1965 to 1970 11.5 g (40%), Morgan dollar 26.73 g (90%), 40% silver Eisenhower collector dollar 24.59 g, Jefferson wartime nickel 5.000 g (35% silver, 1942 to 1945), American Silver Eagle one troy ounce of fine silver.
What this is not. Melt value is the metal in the coin at the spot price you typed. Dealers pay a percentage of it and sell at a premium, and coins with numismatic value are worth more than melt. Weights are the original specifications, so worn coins hold slightly less. Silver Eagles are counted as one troy ounce of fine silver each.
