Found it hanging around in my inventory- how much should I try to sell it for? :/

;; this thread is for items not prices in SS and this item is priced..... and a bit inflated imo.

It's a Cash Shop item, () but has since been retired. According to SubetaHQ it sold for 500 CSC in the CS. So I would think base it off that?

[edit]

So less than 5.5 million
