Selling limited edition items is never fun lol, especially if you spent a lot of money on them. But honestly, for me, it would depend on how much of an attachment you have to Elsa. If she is a character that you absolutely love and you have a strong attachment to, then I would keep her. Because once you sell her, the chances of ever getting her back are slim if we are going by the ridiculous prices the Frozen dolls are going for on eBay. Even if she looks out of place, and you like her that much, I would keep her. But if you just think she is really pretty and there are characters you like far more than Elsa, then I would sell her. Anna alone will give you a good amount of cash I think. Hope I helped at least a little :3.
