Open the full calculator →A 1964 quarter is 90% silver and 10% copper, with a gross weight of 6.25 grams. That works out to 0.18084 troy ounces of pure silver per coin. Because the metal content is fixed, the coin's floor value moves one-for-one with the price of silver — exactly like a small silver bar.
That is why a 1964 quarter is worth far more than 25 cents: at any silver price above about $1.40/oz the melt value exceeds face value, and in practice silver has traded many multiples higher. The figure above is the melt (intrinsic) value of the silver alone; it ignores any collector premium for uncirculated or error coins.

Melt value is the value of the metal in the coin, ignoring any collector premium:
Where the fine-metal content is known, this simplifies to spot × 0.18084 oz. The live figure at the top of this page applies that formula to the current spot price.

A 1964 Washington quarter contains 0.18084 troy ounces of pure silver. It is 90% silver by weight (6.25 g gross), the standard for all US dimes, quarters and half dollars minted in 1964 and earlier.
Yes. Its silver melt value is the spot price of silver multiplied by 0.18084, which is many times its 25-cent face value at today's prices. Worn coins sell close to melt; uncirculated and error coins can be worth more to collectors.
Every regular-issue 1964 Washington quarter is 90% silver. Silver coinage ended in 1965 — quarters dated 1965 and later are copper-nickel clad and contain no silver.
Denver-minted ('D') and Philadelphia quarters have identical silver content and identical melt value. Only the collector premium differs between mint marks.
