You consider selling your chip, else you wouldn't ask here.
So if you REALLY want to learn about the true price of your item, then place it in auction for 7 days,.
Best ending time should be a Saturday around US time zone early peak time, and Europe's late peak time (+/-22:00-24:00 UTC maybe).
With NO increased startbid and NO buyout.
Players will bid on the chip and the highest bid will win.
Which is the item's true price, since noone else is willing to go higher.
