Copper has never been used as a "filler". U.S. silver coins dated 1964 and earlier are made of an alloy containing 10% copper and 90% silver. Copper is necessary to harden the coins to prevent excessive wear. By itself silver is so soft that the coins would have worn out so quickly as to be impractical for daily use.
Present day nickel, dimes and quarters are composed of copper and nickel.
Quarters comprise 8.33% nickel and 91.67% copper.Dimes comprise the same as quarters; 8.33% nickel and 91.67% copper.Nickels comprise 25% nickel and 75% copper.Pennies comprise 2.5% copper and 97.5% zinc.
No, other than silver dimes/quarters created for special collector sets, current dimes and quarters contain no silver and only contain copper and nickel.
Not US quarters. 1965 was the first year that the US struck quarters and dimes in copper-nickel.
Yes, they are all made (partly) of copper. A current nickel (5 cents) is 75% copper and 25% nickel. About the same proportion is used for the softer "clad" exterior of dimes and quarters, with a thin layer of copper in the middle.

Dimes and quarters dated 1965 and later are struck on cupronickel "sandwich" blanks. Halves dated 1965-69 were struck on a silver-copper sandwich. Halves after 1971 are made from the same cupronickel metal as dimes and quarters.
U.S. dimes, quarters, half dollars, and dollars dated before 1965 contain 90% silver with 10% copper.
Since 1965 for dimes and quarters, and 1971 for half dollars, the metal composition is 91.67% copper with 8.33% nickel. Each outer layer is 75% copper/25% nickel, over a solid copper core.
Circulating dimes and quarters dated 1965 and later are made of copper-nickel rather than silver, so they have no extra value.
It depends on their dates and denominations.All cents were made of bronze, an alloy of 95% copper with tin and/or zinc.Up till 1964 dimes, quarters, and half dollars were made of 90% silver and 10% copper.Starting in 1965, dimes and quarters were made of copper-nickel, with no silver. Half dollars were made of 40% silver and 60% copper.In 1971 half dollars were changed to the same copper-nickel composition as dimes and quarters.
3 quarters, 4 dimes
He has 18 quarters (for $4.50)...........and 10 dimes ($1.00)
1 quarter and 21 dimes or 3 quarters and 16 dimes or 5 quarters and 11 dimes or 7 quarters and 6 dimes or 9 quarters and 1 dime
4 quarters=10 dimes x quarters=85 dimes quarter=10/4 dimes x (10/4 dimes) = 85 dimes x= 85 dimes/(10/4 dimes) x=34 Answer: 34 quarters
15 quarters, 3 dimes
10 dimes 5 quarters
US dimes and quarters (along with half dollars and dollar coins) dated 1964 and earlier are made out of 90% silver and 10% copper.
And lots of other things. There are pipes in cars made with copper and quarters and dimes have copper inside of them. There are lots of other uses as well.
2.50 can be made up from 10 quarters or 25 dimes, for the first two ways. The smallest number of quarters that can be substituted for dimes without changing the sum is two, substituted for five dimes. Therefore, you can have: 20 dimes + 2 quarters, 15 dimes + 4 quarters, 10 dimes + 6 quarters, or 5 dimes + 8 quarters, four additional possibilities for a total of six..
There are 39 combinations of dimes and quarters that will total 19.75 from 1 quarter and 195 dimes to 77 quarters and 5 dimes.
I believe there are 19 ways to make ten dollars with only quarters and dimes. Quarters have to be in increments of 2 so there would be 2 quarters and 95 dimes, 4 quarters and 90 dimes and so on til there are 38 quarters and 5 dimes.
7 quarters equal $1.75 2 dimes equal $.20 You can also get it with 5 quarters and 7 dimes. 3 quarters and 12 dimes and one other way.
If 5 dimes to every 8 quarters that is 5 out of every 13 coins dimes and 8 of 13 coins quarters 5/13 x 520 = 200 dimes
10 quarters and 7 dimes =
