Presuming that you are referring to US dimes issued between 1875 and 1964 (dimes older than 1875 had different weights and/or fineness), dimes weigh 2.50 grams and are 90% silver (the remaining 10% is copper). This means that the ASW (Actual Silver Weight) is 0.07234 troy ounces. Thus, it would require 14 dimes (this number is rounded up; the precise number is 13.8236 dimes) to have one troy ounce of silver.

For modern U.S. quarters like you find in change, none. They don't contain any silver - they're made of copper and nickel. For quarters dated 1964 and earlier, each one cont…ains 5.625 gm of pure silver, almost exactly 1/5 of an ounce. So 5 old quarters contain a total of 1 oz of silver.
Except for the famous "war nickels" made from mid-1942 to 1945, the answer is "none", because all other US nickels don't contain silver. Since 1866, the coin has been made of …an alloy of 75% copper and 25% nickel. If you have war nickels with a large mint mark on the back, these do contain a small amount of silver - 1.75 gm to be exact. Because one troy ounce is about 31.1 gm, you'd need 31.1 / 1.75, or about 18 war nickels to contain a troy ounce of silver.
Each Kennedy half that was minted in '64 or earlier had .36 troy oz of silver meaning a little less than three would equal an ounce of silver which is running for 29.30 an oun…ce last i checked. Half dollars made 1965-1970 contained only 40% silver, instead of the 90% of earlier coins, so it would take more coins. Half dollars made after 1970 contain no silver.
One troy ounce of silver = about 31.1 grams.
Any combination of 90-percent silver U.S. coins which have a face value of US$1.00 contains 0.715 troy ounces of 99.9-percent silver (0.7234 troy ounces if uncirculated), exce…pt for the silver dollars (Morgan and Peace) which contain .7736 troy ounces of silver. In other words, a full troy ounce of 99.9-percent silver is contained in any combination of 90-percent silver U.S. coins which have a face value of US$1.40. Therefore, a roll of uncirculated 1964 dimes contains 3.617 ounces of pure Silver, while a roll of circulated 1964 dimes contains 3.575 ounces of pure silver.
No true silver dollar (1794-1935) has a full ounce of silver. The Actual Silver Weight is .77344oz of pure silver. So less then two.
14 Mercury Head dimes = a little more than ounce of silver. Each dime has .07234oz of pure silver in them.
No Kennedy DOLLARS exist. But 7 Kennedy halves dated from 1965 to 1970 would have 1.0353oz of silver.
3 well equal a little more than a ounce of silver.
That's a trick question with at least 3 answers: If you're referring to modern (1965 or later) dimes the answer is zero because all circulating dimes issued since then are m…ade of cupronickel, not silver. If you're referring to 1964 and earlier, these coins weighed 2.5 gm and were 90% fine so they had 2.25 gm of pure silver. For these coins: > a standard American ounce is 28.35 gm, so 28.35 / 2.25 = 12.6 dimes. > a troy ounce (used for precious metals) is 31.11 gm so 31.11 / 2.25 = 13.8 dimes
There's NO silver in nickles
In US Coins
14 silver dimes equal just a little more than 1 troy oz. Each coin has .07234 oz of pure silver.
