Hi Billy. After reviewing a number of cards, I can say ... I'm not exactly sure. I think it's a very dark blue foil, but it certainly appears black, especially in low light. Turning the card to see how light reflects, on a couple of spots it reflects blue, in others the reflection is the team color. I can tell you this, it is absolutely retail, as I bought the packs retail. And if hobby box is gold, then from our description, neither of us have hobby cards. I would believe we are describing the same cards, with nuances that are in the eye of the beholder.
