I am hoping to sell it cause I have no use for it, however there are none on the market. Is there a sort of general range I should aim for?

You can find it in the Cash shop, under the Costume trunk tab, in the medieval helmet for 40CSC.^.^
Do you have a rare item that just won't sell? Are you going through the high levels of Item Hunt? Or maybe you just HATE that blue bunny? Then you should join IHH helpers and IHH bargain in the forum groups!
Thank you but! I am still unsure as to how much it would be to sell if its only 40 csc

Decide on your price for CSC, i usually use the 500 credit card and 100 credit cards as a baseline comparison. Currently the 100 csc card is 9.35M or 93,500 per point. The 500 csc card is 47M or 94k per point. That would put your egg X40 for each or between - 3,740,000 and 3,760,000. You may in fact, be able to price it slightly higher and have someone snatch it up for not having to buy csc and able to use pure (like 4.5-5M). Being the only one in the SS you could technically put it at whatever price your heart desires, but the only people who would buy it at that point are those that are unaware they are currently buyable. Does that help?
