There was an old glitch in the game where if you logged into a members server and equipped a members item, then logged off and logged onto an F2P, the item would still be equipped and everyone could see it, I remember walking around Varrock in F2P w/ my Drag BAxe equipped... good times LoL but yes, there is no possible way to trade a "members object" while on an F2P server...
