Yes, the reason why quarters (and dimes, and half dollars) dated 1964 and earlier are worth more than their 1965 and later coins is because they are 90% silver.
The coins have an Actual Silver Weight (ASW) of .36169oz of pure silver.
25 cents, unless they are date 1964 or before, then they are 90% silver.
US quarter dollars issued through 1964 were 90% silver. Quarters issued from 1965 onward (except for some proof coins made for collectors) contain no silver.
US dimes, quarters, and half dollars dated 1964 and earlier are made of 90% silver and 10% copper. The same ratio is in dollar coins dated 1935 and earlier. For coins dated 1965 and later, the only ones to contain any silver are half dollars dated 1965 to 1969. They're 40% silver. Any other date or denomination is either cupronickel or brass ($1 coins only, in brass).
U.S. quarters dated 1964 or earlier are 90% silver and 10% copper, they contain .18084oz of pure silver.

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.
In unworn condition, 6.25 gm. Current copper-nickel quarters weigh 5.67 gm.
Pre 1964 quarters are made of 90% silver. Sterling silver is 925%. So no. Yah that's right. But I think you missed a decimal point out! Sterling silver is 92.5% pure also denoted 925 in millesimal fineness
Pre-1965 silver quarters are 90% silver with a total weight of 6.25 grams, which is then 5.625 grams of silver per quarter.
US dimes, quarters, and half dollars dated 1964 and earlier are made of 90% silver and 10% copper. The same ratio is in dollar coins dated 1935 and earlier.

Any other date or denomination is either cupronickel or brass ($1 coins only, in brass).
They aren't rare, they are, however 90% silver and worth a bit over $5 each at the time of writing in silver content alone. Many, many, many, pre-1965 quarters were made but simply the fact they were made out of silver is what makes them valuable. Now, there are, of course, some rare years of silver quarters, but there are also very common dates (like 1964).
