Twin Grakatas Riven, Value?

[PandaBandit209]

So I got a Riven for Twin Gremlins and I'm no where near high enough MR to use it yet, I was considering selling it but I'm not sure how much it'd be worth
the stats are:

+241.1% Damage
+138.4% Multishot
-33% Firerate

What kind of prices am I looking at and should I just re-roll it? (It's unrolled atm)

are those stats at max rank?  On riven.market there isn't one with the same 3 modifiers, but there is a rank 8 with +427% Damage +234% multishot -34% magazine capacity that is 2400 plat.  If yours is max rank then id probably guess 300-500 is what you could find a buyer for?  If those stats are unranked you might have yourself something worth 1-2k range.  At the end of the day it is a matter of finding the right buyer though.
