A pound of dimes is worth about $20. The value of a pound of dimes can be calculated based on the weight of 2.27 grams for each dime produced by the U.S. Mint.
Since 1 pound contains 453.59 grams, the number of dimes in 1 pound can be calculated by dividing 453.59 grams by 2.27 grams for a total of about 200 dimes. Since each dime is worth 0.10 dollars, or 10 cents, the value of 200 dimes is $20; this value is determined by multiplying 200 dimes times 0.10 dollars. The value of a pound of any other denomination of coins can be calculated the same way.
