Tu Tu Tails is probably worth $6-8 in good condition. The original 12 are the most common ones. I'm not one to tell customizers never to bait a vintage item, although you may want to find one with manky hair to customize if anyone is interested in buying her. You have to find someone who is looking, though--some MLP collectors also collect the FT birds, but often only when they can get them in a lot or with their accessories.
