Not sure about the rest, but ...
I recently sold an r10 15wE plagueborn axe for 5k, the high bid on a fansite auction. I would think 15stance might get at least that, if not more. I would think the r10 15^50 axe might get 10k or more, too.
I recently had a pair of r9 +5 plagueborn daggers just like the ones in your picture. I met a player in Kamadan asking for a pair and offered mine for 35k. They accepted immediately.
After trading, I asked how much they'd have been willing to offer for the sake of better PC info in the future. They told me max offer would have been 45k. (So I'm posting that here ... for the sake of better PC info for all of us ... if we use search.)
Granted, anything like this is almost never fast or easy to sell when you get them or buy if you're shopping for something specific, so that may have simply been my good luck to stumble into a particularly motivated buyer?
But you might aim a littler higher than 25k to start on daggers like that.
And from what I've found, I agree with Stuey, too - it is generally NOT a good investment to try to add mods to weapons ahead of time just to sell them. Let the new owner decide just what mods he wants and put them on himself. Don't waste your money trying to guess.
