Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.

It would all depend on the mix. If you had 180 pounds of pennies and the other 10 pounds were nickels, dimes and quarters that would be worth a lot LESS THAN if you had 180 pounds of quarters and the other 10 pounds were pennies, nickels and dimes.

15Call the number of nickels n and the number of dimes d. From the problem statement,d = 2n - 12 and 0.05n + 0.10d = 2.55. Substitute the first of these equations into the second to yield 0.05n + 0.10 (2n - 12) = 2.55, or 0.05n + 0.20 n - 1.2 = 2.55, or0.25n = 3.75; n = 3.75/0.25 = 15; d = 30 - 12 = 18.

1937 is an extremely common date for buffalo nickels. Most are worth less than a dollar.

A. One nickel weighs exactly as much as two dimes but less than a quarter. . . If you cut a quarter into 10 equal pieces, each piece would weigh 0.57 grams. If you had 75 of those pieces, the total weight would be the same as the weight of 19 dimes. This information is accurate to two decimal places, but is only the average of the three nickels I happen to have in my pocket today :-) ---- +++ Actually, the precise answer would be 4.5 grams/nickel. 75 pieces (of a quarter) x .57 grams = 42.75 grams42.75 grams / 19 dimes = 2.25 grams/dime2.25 grams * 2 dimes (1 nickel is equal to two dimes) = 4.5 grams This assumes the information of a quarter equaling 5.7 grams is correct. So, multiply 5.7 by 30 and you get 171 grams! ~Kyle Michel~Very Experienced Coin Collector~ Per information from the U.S. Mint website and PCGS's CoinFacts.com, the U.S. nickel was the first metric coin. Its nominal (i.e. standard, right out of the mint) weight is 5.00 grams. Note that because the nickel was initially struck as a coin whose size did not correlate with the intrinsic value of the metal it contains, while old silver dimes and quarters DID contain their intrinsic value in metal, it is not possible to compare the ration of the coins' weights to the ratios of their denominations. The problem is further complicated by the fact that modern dimes and quarters are 83% copper and 17% nickel overall, while 5Â¢ pieces are made of an alloy of 25% copper and 75% nickel. Attempting to determine value/weight ratios would involve some pretty messy arithmetic, a lot more complicated than going to the Mint directly.

Let N be the number of nickels. The value of nickels is 0.05N and the value of dimes is 0.10(2N-12). We can form the equation 0.05N + 0.10(2N-12) = 2.55 and solve for N. After solving, we find that there are 9 nickels.

Both nickels and dimes are composed of Copper and Nickel. A dime, however, is 91.67% Copper and 8.33% Nickel, while a nickel is 75% Copper and 25% Nickel. Since Copper is a bit denser than Nickel, and a dime contains relatively more Copper, than a dime would be denser than a nickel.

U.S. dimes were 90% silver through 1964. The only nickels to ever contain silver are "war nickels," dated 1942-1945, distinguished by the large mint mark on the back.

It would all depend on the mix. If you had 180 pounds of pennies and the other 10 pounds were nickels, dimes and quarters that would be worth a lot LESS THAN if you had 180 pounds of quarters and the other 10 pounds were pennies, nickels and dimes.

It's a common misconception that because dimes, quarters, and half-dollars were made from 90% silver up to 1964, nickels were also silver. In fact, US nickels made from 1866 to late 1942 and from 1946 to the present are made of a copper-nickel alloy, not silver. From late 1942 to 1945 nickels did contain a small amount of silver because nickel metal was needed for the war effort. Those "war nickels" are the ONLY ones that have any silver in them. At silver prices in effect as of mid-2015 these coins are worth less than $1 for their silver content.

15Call the number of nickels n and the number of dimes d. From the problem statement,d = 2n - 12 and 0.05n + 0.10d = 2.55. Substitute the first of these equations into the second to yield 0.05n + 0.10 (2n - 12) = 2.55, or 0.05n + 0.20 n - 1.2 = 2.55, or0.25n = 3.75; n = 3.75/0.25 = 15; d = 30 - 12 = 18.

They are the same amount but I'd rather have a trunk half full of dimes because it's more convenient to have less coins than more if they both equal the same.

Twelve. Here is how: Using cents rather than decimal dollars: 5n + 10d + 25q = 640 Express the numbers of nickels and quarters in terms of the number of dimes: # of nickels = twice the # of dimes ==> n = 2d # of quarters = 5 less than the # of dimes ==> q = d-5 Substitute for n & q in original equation: 5(2d) + 10d + 25(d-5) = 640 45d - 125 = 640 45d = 765 d = 17 ==> 170 = $1.70 n = 34 ==> 170 = $1.70 q = 12 ==> 300 = $3.00 . . . . . . . . . Total = $6.40

It is a common date among Buffalo nickels and is worth less then $2 unless it is in perfect condition.

Buffalo nickels were made from 1913 to 1938. The US didn't even exist, much less issue coins, in 1726
