http://backpack.tf/vote/id/508eedbeba25363907000010 my comment here lists most of the actual sales. some are a day or 2 old though. price is certainly dropping like all halloween items and there are a number sitting unsold at 1 ref (see links on this suggestion) even though many have gone for more. lowest actual sale price found was .66, did not find any sitting at this price. This tells me current price is sitting at a little under a ref.

follow-up, link one relisted at .66 and had 2 adds for it within 30 minutes
