My cousin twice removed recently passed away, and he left me (among other things) his gun collection-- consisting of a bunch of shotguns and two S&W revolvers. I sold the shotguns at auction, but the revolvers called to me, so I hung on to them-- and now I'm trying to figure out how much they might be worth, and if I should keep them or sell them. These are the first guns I've ever owned, though I've shot other peoples' guns occasionally, so I don't have much experience in these matters.
The first one is a .38 Special Model 15-2, S.N. K735XXX, with a 2" barrel. It looks to be in excellent condition, though I don't know enough about guns to tell if it's ever been fired:
It has an accompanying box and cleaner, although the box belongs to a different gun-- both the S.N. and model # are different:
The box is dated July 23, 1968 on the inside of the cover.
The second gun is a .22 Combat Masterpiece, Model 18-3, with a 4" barrel, S.N. K904XXX. It's in just about the same condition as the .38:
It also came with a box, which matches the gun, although it suffered some damage (water damage? but the gun itself is fine) from sitting in a closet for the last 30-40 years:
The box has the original wrapping paper, manual, and warranty card in it, but doesn't have any dates stamped on it.

So I guess what I'm asking is: how much are these worth, and should I keep them or sell them? I'm not really a big gun person (at this time, at least!) though I would like to shoot them if it won't drop their value. If there are millions just like 'em floating around and they're only worth a couple hundred bucks each, I'll probably keep one or both of them, but if they're valuable, I'd probably want to sell.
What do you think?
