Hello there! That's a fantastic question. Understanding the value of old coins is a fun part of collecting.
The value of a 90 percent silver quarter is tied almost entirely to the amount of silver it contains and the current market price, or "spot price," of silver. These are typically U.S. quarters that were minted before 1965, and as the name suggests, they are made of 90% silver and 10% copper.
Each of these quarters contains 0.1808 troy ounces of pure silver. Because the price of silver is constantly changing, the exact value of the quarter fluctuates right along with it.
To give you a clear example based on the information provided, when the spot price of silver was $29.15 per troy ounce, the melt value of a single 90% silver quarter was $5.27. You can always find the current value by multiplying the current silver spot price by 0.1808.
Keep in mind that this is the melt value. While most common, circulated silver quarters are valued this way, a specific coin could be worth more to a collector if it's a rare date or in exceptionally good, uncirculated condition. For the most part, though, its worth comes directly from the precious metal inside
