To determine how many quarters make an ounce of silver, we first need to know the silver content of a quarter. A standard U.S. quarter (post-1964) contains no silver, while pre-1965 quarters are 90% silver, weighing approximately 6.25 grams. Since an ounce is about 28.35 grams, it would take roughly 4 pre-1965 quarters to equal one ounce of silver.
A pre-1964 nickel weighs 5 grams.

A 1964 Roosevelt Dime has .07234oz of pure silver. as do all pre-1965 Roosevelt dimes regardless of date or mint mark. Those dated 1965 and later are made of copper-nickel.
In unworn condition, 6.25 gm. Current copper-nickel quarters weigh 5.67 gm.
None. Please don't assume that all pre-1965 coins contained silver. Except during WWII, US nickels never contained silver - they've always been 75% copper alloyed with 25% nickel. From 1942 to 1945 special "war nickels" were made that contained about a gram of silver, because nickel was needed for the war effort. A 1964 U.S. nickel contains 0% silver. Only nickels issued from 1942 thru 1945 (known collectively as 'war nickels' and distinguished by their large mint marks, hovering over Monticello on the reverse) contained any silver, 35% by weight.
