PC: CoA grim cesta

Sorry if this is a silly question (new to the site), but I'm wondering how much the Cities of Ascalon -50hp grim cesta should go for. I'm getting conflicting opinions in game ranging from 3k to 15k, and since that's a bit of a range, I was hoping someone could help me out.

Oh, also is there any demand for the scroll that's the other item reward from the quest at all?

I usually see people to try and buy it at 7-8k in Temple of Ages.

I don't think the other scroll has any demand.

5k /.
