Or How much are they worth?

I'm not sure how much to ask for one of these because I almost have enough Referral Points to buy them (Currently I have 11 and it won't take long to get the other).

Can any of you help me out?

It seems like most people end up getting between 12-15mil per point on the higher end items, putting them at around 144-180mil.

I think I have seen them go for a little less than that too though.

Personally, if I had one, I wouldn't take less than 180. If you run up against a competing seller, dropping the price as low as 140ish isn't awful though.
