I have these Planescape Faction buttons from Gencon my friend gave me.  He got them in what he thinks is 1996.  Apparently from what Jim that helps in the Gencon Auction Hall says they were handed out at Gencon in 1994 and people got to get 1 pull from a box of buttons so it wouldnt be easy to get all of them.   They have (c) 1994 TSR, inc. on all but 1 of the buttons.  There are 14 buttons which my friend believes is a complete set but planescape faction lists show 15 I believe.   I was wondering if anyone knows if this is a complete set and if anyone has seen a set of these sell anywhere?
