I think that we will need a list of dates and mint marks to give you better ideas. however the 65-69 halfs are 40% silver, 64 and older are 90% there are early 70 silver clad versions as well. the Kennedies if circulated are basically bullion coins, if you are not a coin collector or PM stacker you can easily sell these at spot.
There are rare versions or proofs that may be worth more, if you have one or 2 coins you have specific questions on please post some pictures, there are lots of experts here.
also do not clean your coins, this is a bad thing, you can hurt the value if you do have something with numismatic value.
