My first question would be....Is he a true pink eyed albino, or just an all white deer with blue or brown eyes?
If he is just an all white deer without pink eyes, I would say he is worth about $1500 more than a regular brown deer of the same age/size.
If he is a true pink eyed albino, then he would be worth more. How much more is hard to guess. The reason is, there are very few of these. Depending on where you are an how frequent this happens in the wild around your area would be an influence of the value.
