A pound of dimes is approximately $20 in value. The weight of 2.27 grammes for each dime minted by the US Mint can be used to calculate the value of a pound of dimes.
Because one pound contains 453.59 grammes, the amount of dimes in one pound may be estimated by multiplying 453.59 grammes by 2.27 grammes, yielding about 200 dimes. Because each dime is worth 0.10 dollar (10 cents), the total value of 200 dimes is $20, which is calculated by multiplying 200 dimes by 0.10 dollar. In the same way, the value of a pound of any other denomination of coins can be computed.
