A pound of quarters is worth how much?

Answer 1

The Oklahoma State University - Department of Chemistry illustrates

that one pound of quarters are worth $19.90 or $19.75 in quarters

using the following calculation:

1 lb = 454 g

1 dollar = 4 quarters

1 quarter = 5.70 g

1 lb X 454g X 1 quarter X 1 dollar = 19.9

1 lb 5.70 g 4 quarters

(actual would be $19.75 in quarters)

CorrectionThe above answer, despite coming from a university science department, makes a couple of assumptions. (*)

> It assumes the quarters are all modern clad coins made of copper-nickel. Up till 1964 US quarters were made of 90% silver and had a mass of 6.25 gm when new. So if any of the quarters were silver there would be fewer of them in a pound but the current price of silver would result in a much higher metal value.

> The masses shown are rounded to 2 or 3 significant digits. It's not a major difference but it affects the final answer: According to the US Mint, the nominal weight of clad quarters is 5.67 gm each, or 0.20 oz. The weight standard was set before the Mint "went metric" so the weights of clad dimes, quarters, and half dollars were established as fractions of ounces.

So at 1/5 of an ounce, there are exactly 80 clad quarters, not 79, in a standard US pound.

(*) Disclosure: I'm a former college science professor as well as a numismatist so I have a couple of chops in both areas of knowledge

Answer 2

It would depend upon whether the quarters were 90% silver or present day clad coins.

Answer 3

20 dollars
