Most OBW rolls have been improperly stored at some point. I know exactly what you're describing. Also, there are many fakes in the market made-up of primarily MS-63 and below rejects. You're going to have fun with that roll set! Not only is it fun constantly upgrading coins, your primary collection will also benefit.
Had to go check mine, I think you win! Your strike is better, I'd like to see better pictures of yours. Mine has mirror surfaces:
I don’t have much of a set up for coin photos yet, using my iphone at the kitchen counter, lots of maneuvering to get decent light. Maybe Santa will bring me a copy stand and a camera I really like this one, I’m not sure I’m great at picking out a great strike from an average one, but I feel like I can pick out the ones with clean fields. I’ll try posting a couple of my other ones soon.
