i have 9 half dollar coins the years are 1965-1969 i found them all under my house are they worth anything?

Answer 1

They are 40% silver, which means that they are worth about $1.75 each as silver.

For the individual that responded below, I know of at least four coin shops within 10 miles of here that will pay 3x face for these. Not a collector, are you?
Wiggle your toes. They're tasty.

Answer 2

Good luck finding a smelter who will pay you bullion price for your 9 coins. (get real Zoxx)

To you they are worth 50 cents each unless they are "proof" coins but I doubt it if they were under your house. Go spend your new found wealth on a combo meal at McD's.
