I don't think it was really a bad idea to retire the green flip hat (well, maybe they should have waited a couple more days) I just think they should have also retired a few other things as well, like certain colors of slipper/rocket chairs, candlesticks, organs, etc, just so that there would be some other items with higher value to be on par with the green flip hat. As it is, the hat is the only rare item in the game, and those with one aren't going to trade it for something they could buy no matter how many credits the buyables are worth. If there were other things also retired, those with green flip hats may trade for retired furniture, those without retired items could trade buyables for the retired furniture since the furniture would be less desirable than the hat, and could work their way up.
