There's nothing to improve on for a pack fresh note. Beware of sellers who over use this term. Ebay does not offer 3rd party reviews like auction houses.
Obviously you won't get an independent review if any auction company is selling out of their own inventory and that happens a lot. No auction company gives you a return policy except ebay. Stacks&Bowers and Heritage auctions neither offer a reliable return policy especially when they sell a note out of their own inventory and this happens a lot. You are just stuck with a misrepresented item with them. At least with ebay you always have a return option after personal inspection and this is VERY important because no degree of picture quality will show every problem a note may have. None! Unless you can visit an auctions in person for a face-up inspection you have no reason to trust the pictures auction houses provide.
Choose wisely and never forget, an item can only be original once. Avoid processed notes.
