Just received word on two different variations of the silver Platinum Vegas World card. They feel like different thickness plastics but they're actually the same total physical thickness -BUT- on one card the front silver layer of plastic is thicker than the white back layer of plastic and on the other card it's reversed with the front silver layer being thinner than the white back layer. Pretty visible when holding the edges of the two cards together for comparison. I just added a comment to the guides to document the finding but didn't list it as a separate issue/card.
