I don’t have any first hand experience with either of those models and I am not in the market, but I will try to give you my thoughts based mostly on recent gunbroker sales. Neither model is particularly scarce on in high demand nor is it possible to tell condition from a few pictures, especially chambers and bore, but both look to be above average with normal wear.
The Richland 200 SXS is a field grade with fixed chokes, of curse nothing wrong with that, just not now as desirable as some of the more modern choices. Probably in the $225 to $250 range.
The Super Blackhawk also looks to be above average with normal wear for a blued gun and might sell in the $450 range. The ammo is a little harder to guess, but probably somewhere in the fifty cents per round range if pricing it with the gun, and for a quick sale you might just have to throw it in to make the deal. Of course these are just guesses and YMMV.
