That looks like a very nice albino, but I'd hesitate to say she's a coral albino. They are usually a lot more pink. Perhaps the pics don't show that though....

The BoaMorph site has a nice description of the coral albino and the genetics behind the trait and there's a few pics here too. You can see how pink these boas should be. Some corals are more pink than others, but all corals will have some pink highlighting and should not look yellow.

As far as price, a 2009 coral albino female will go for around $500-600. Knock off $100 for a male. The more pink, the higher the price. If she turns out to be a normal albino, you're looking at about $400-450 or so. Study the pics and look at this girl in person. If she's nice and pink, you're better off. The pic here really may not be showing her true colors and she might be much pinker in person.

If you really want her for yourselves, she'll be worth a little more to you. She looks nice and healthy - in fact, she's a little fat, lol...
