Best Answer

It depends on the year the coin was minted.

Quarters made since 1965 are copper clad with cupronickel, and weigh 5.67 gm each. Interestingly that's 0.2 US ounces so even though coins are measured in metric units, exactly 5 quarters weigh one US ounce.

From the 1870s to 1964, US quarters were made of 90% silver/10% copper and weighed 6.25 gm. A US ounce is 28.35 gm so doing the division works out to about 4.54 coins per ounce.

Modern US quarters weigh 5.67 gm each, or 1/5 of a US ounce. There are 16 ounces in a US pound which is 80 quarters, or $20.

A modern (1965 or later) US quarter weighs 0.2 oz. so there are 5 per ounce, times 16 ounces in a pound = 80 quarters.

Current US quarters weigh 5.67 gm, which is 0.2 US ounces. That means five quarters weigh one US ounce; a pound is 16 ounces so it's the same weight as 16 X 5 = 80 quarters.

One 1964 or earlier silver quarter= 0.1808 of an ounce of silver. So, it takes about 6 90% silver quarters to make one ounce of silver. 6 silver quarters= 1.0851 ounces.

US silver quarters weighed 6.25 gm. If you're referring to standard American weights, 1 ounce is 28.35 gm so it would take just under 5 quarters to equal an ounce. If you're referring to silver weight, the coins were 90% silver (i.e. 5.625 gm of pure metal) and a troy ounce is about 31.1 gm so you'd need about 5½ quarters to yield a troy ounce of silver.

One 1964 or earlier silver quarter= 0.1808 of an ounce of silver. So, it takes about 6 90% silver quarters to make one ounce of silver. 6 silver quarters= 1.0851 ounces.
