I'm not that experienced on PCs, but I think that might be merch food... you could salvage the poisonous mod and sell for like 1k? but I think that might take a bit long to sell...
I agree with the above for the bow. It's a common base skin, req10 and non-insc.
As for the scepter I don't know; it's not max damage and one of the mods isn't perfect but it's not a common skin and at least it has dual mods. Probably worth alot more than the bow at any rate.
