In DW Black Market the price of the item changes colour to let you know if a fellow guild member has high bid. To show the same thing here, I suggest that you change the color of the Money value to green to inform other Galaxy members that one of their Galaxy members has current high bid.
Musty you missed out one thing, you should also mention about friends who bid as well , I recommend that the color of the bid to be Blue, for gal mates Green maybe? But, if friends + Gal mate = Purple
