Your best bet is to sell her auction style. She isn't easy to find and she can easily go for $200 from what I've seen based on sold listings.
As an aside, I got her for around $60 last year because an eBay seller had about 7 of her up at a fixed price. Those all went immediately, especially since she was going for $100 then. Her price just keeps going up, so I don't think you'll have any problems selling her. Good luck!
