Since I scored that Dolch PAC 65 (thread in the vintage section), I've been doing some reading on the old keyboards.
They're actually called mechanical keyboards and there's a big revival around them. They've actually started manufacturing new mechanical keyboards and they're pricey as hell.
As far as I can tell, people are in love with both the mechanics behind it and the "caps" or keys themselves. On that Dolch that I picked up, I've found that they're wanted more for the keyboards than they are the actually computers.
Ebay would likely be the best place to sell them. Just do your research to figure out what they're going for.
