Unfortunately there aren't many libraries anymore that would be interested in having them, and unless they are rarities, it is unlikely you could get much for them on sale at eBay or disposing of them at flea markets either.

They're like anything else, they are worthless unless you can find someone who wants them.

Of the ones you have mentioned, I would doubt that there are any rarities. As far as the CWG is concerned, and maybe the rest of the gospel stuff, I can put you in touch with someone who MIGHT be interested. It has been a good while since I corresponded with this particular person, but I could check if you wish.
