Yes, but I don't think there is any definitive answer. Most likely these were store samples and the unique serial provided a means by which oakley could track what stores where leaking them to the public, (which they were not supposed to do)
That's a sales sample, I've seen another with that prefix that belongs to a member here. It's an oddity for sure but I don't know if it still necessarily increase the value as you wouldn't be able to find one with a matching box and coin.
NAL might be for Lenscrafters.
