[PS4] [Q] [Price Check] - Castanas [Riven] (+Cold/Multishot/Fire Rate)

Hey folks,

I've just started running Sorties, and I've picked up a couple of Rivens. From what I can tell from looking at The Internets, Castanas rivens seem to be quite valuable, but I don't really know what to look for stats-wise. Can anyone advise as to what kind of price I might get for this?
