Didn't see any for sale or trade. Anyone have an idea of pricing?
well it comes from the magical folding chess set which originally cost 500 CSC but is unavailable and there are none in shops. pieces from trunks are usually worth less than the trunk they come from, but how much less depends on the desirability of the item. however, since the trunk this item comes from isn't even available in the first place, i'd say start by pricing it at 50 mil. it probably won't sell for that much but it might, and if it doesn't after a couple of weeks i'd start lowering the price by 10 mil a week until it sells.
I wouldn't price it that high, personally. I sold a Magical Folding Chess Set not long ago and had a really rough time trying to sell it for 50m - I think I sold the thing for around 35m in the end. Nobody will buy one item at that price, in my opinion. I'd probably try my luck at around 25m, but it's up to you. There aren't any others.
