There's no such coin. All circulation quarters minted in 1965 and later are made of copper-nickel, just like dimes dated 1965 and later, and half dollars dated 1971 and later, as well.
Anything you find in change with those dates will be worth face value only.

$50
The coin is face value.
The silver value is about $6.00. NOTE: The US has never made a pure silver quarter, they are 90% silver & 10% copper.
I believe that a 1922 quarter is made of almost pure silver with a value of about $3
