Unknown Silver: Help Me Identify

[Shami-Amourae]

I like to buy random lots from coin dealers since the prices are cheap. Recently I got some stuff I can't identify, so I thought it would be fun if you guys helped me out:

I have 2 sets of coins here.



The first are 3 Kennedy Halves that are newer than 1970. All weigh 12.5 grams, are brilliant uncirculated, and have Silver rims (no visible copper.) I did the sound test and they sound like normal Silver coins. The Kennedy's all have S marks on them (San Francisco Mint,) and I have the years 1994, 1996, and 2003. What is the percentage Silver on these? Are they 90% like the 1964 Halves? I'm assuming someone bought a proof set from the Mint then broke the proof case to sell them into circulation or something?
The second are 2 Silver Washington Halves. They both have to year 1982 (250th anniversary of Washington,) and I found information online, but still can't figure out what percentage of Silver they are. Both of those are D mark to the right of Washington's horse (from the Denver mint,) and what looks like a EJ mark to the left of it.

The Kennedy halves are proofs and if memory serves me, all proofs are minted at SanFran and are 40% 90%

The other 2 are 90% http://www.providentmetals.com/1982-george-washington-commemorative-silver-half-dollar-us-mint-brilliant-uncirculated.html

The bar I have no idea about.

Yeah I'm worried about the Kennedys. I want to make sure they are 40%, 90%, or whatever. I question if they are 40% though since normal 40% Kennedy halves weigh 11.5 grams, and these weigh the same as 64' Kennedys. I think I got ripped off on those specific coins. I bought a GIANT lot and sorted through them all and got a Barbers, Walking Liberties, Franklins, and 64' Kennedys. Overall I'm happy with the haul though.

I was wrong, they're 90%

Looks like I got a good deal then.A good deal's better than the alternative of a bad one.

What did you pay for the proof half? Don't think I've ever seen one out there in the wild, good find. Here's a half that came with one of my silver proof sets, I've bought at least one every year since 1999 (the 1st year of the state quarters).
