Rob DewolfEric,
I know I've read opinions on this board from more than a few people who think that higher grade Polar Bears carry a premium because it's tougher to find Polar Bears without the product stains, given that they were packaged differently than the other brands. So while the Polar Bear backs themselves are not scarce, they're at least a bit tougher to find in higher grades.
Again, just passing along what I've read here previously.
