What is the silver value of silver coins?

Dimes, Quarters, Halves and Dollar Coins minted before 1965 are 90% silver. To find the value, Take the current silver spot price and multiply by .715. That is what $1.00 face value is worth in silver. Regardless of denomination (dimes, quarters etc.) this still works. Example: The spot price for silver on Kitco.com today was $30.50 per troy once. Multiply $30.50 X .715 = $21.81. So, 4 quarters, 10 dimes, whatever makes $1 face value in silver coins was worth $21.81 today. Silver is always traded by weight, so if the coins are worn, that will be less. If the coin is rare or has intrinsic collector value, it could be worth more. Coins worth more than face value only because of the silver content are referred to as "Junk Silver".
