T - 7 = J T + J = 71, substitute: T + (T - 7) = 71, 2T - 7 = 71, 2T = 78, T = 39, and then J = 32

The total to this question is $10,76,000 in U.S. Dollars.
An pre-1965 U.S. dime weighs 2.5 grams total. The silver content of pre-1965 dimes, quarters, halves, and silver dollars is 90% silver by weight, so there is 2.25 grams of silver in an unworn, uncirculated pre-1965 U.S. dime.
Up to and including 1964 they were 90% silver. After 1965 they contained no silver except for special coins the mint produced for collectors.

Well it all depends on how much, and the quality of your sterling silver. I myself got a total of $456,083 for mine. You should get atleast 300,000 dollars though.

Silver coins dated before 1920 are sterling (.925%) silver. Dollars, half dollars, quarters and dimes from 1920 - 1966 are all 80% silver by weight. An easy calculation to figure out the pure silver weight: Multiply .6 oz per dollar of coinage. Example: $10 of 1966 dimes would be .6 x 10 or 6 oz's of pure silver. Multiplying the total by today's price would give you "melt" value of the coins.
