how much silver is in a 90 quarter

[AndrewRose]

Unlocking the true value of old coinage is a fascinating endeavor, and the U.S. 90% silver quarter is a perfect example. When you're looking at a quarter, the most important factor for determining its silver content is the year it was minted. You'll find that any U.S. quarter dated 1964 or earlier is a valuable piece of history made from a 90% silver composition.

Based on its metallic makeup, a single 90% silver quarter contains exactly 0.1808 troy ounces of pure silver. This specific amount is the standard used by collectors and investors to calculate the coin's intrinsic "melt value," which is its worth based purely on the silver it contains. The remaining 10% of the coin's weight is copper, which was added for durability.

This is why it's always a wise move to check the dates on your change. Quarters produced from 1965 onward contain no silver at all. Finding a pre-1965 quarter means you're holding not just 25 cents, but a tangible asset whose value fluctuates with the daily price of silver, making it significantly more valuable than its face value suggests.
