If your snake did not come from a proven line of Het Black Eyed Lucy, then it is just a nice light normal until you prove it to be something else. As is, your snake is probably worth $300 or so, as a dinker and a big female-assuming it is a female. If I was you, I would buy a male Het Black Eyed Lucy and prove her out one way or the other. Then, when you sell her, you know what to ask. If you sell her as a Fire, and you ask Fire money, and she proves out to be a normal, you are going to have some issues on your hands. Sell her as a dinker for $300 or keep her and prove her out.
