Its rarity is 150 and it's a weapon. I have no idea how much to sell it for.

It's in the Millionaire Center for 60m, so I would say that. Or lower if you don't mind going lower than that, which it would most likely sell faster as well.

They come up on shop search every so often at 50mil. I would say 45m - 60m :)

Does 47mil seem like the best bet? c:

Im sure it would be pretty snapped up at 47mil. I would try to get 50 - 55m first. Put it in your trade and see what type of offers you get. If noone buys put it in your shop for 50mil.
