I assumed that the MLB Holograms had changed over time, much like the look of the database did earlier this year. Most of the holograms I see have a QR code on the left hand side. I was looking at an item authenticated at Great American Ballpark earlier this season, and the hologram on it doesn't feature a QR code. Is this an old sticker they still had laying around? Is there a specific time that these changed? Not that a normal everyday collector would have the means to do so, it seems that the stickers sans-qr code would be much easier to fake.
