Sorry, I created the thread before I typed my message.
I've come across a bunch of these "Rookie Gems" cards on ebay. I'm assuming they're unlicensed custom cards, but I'm seeing so many of them that I'm beginning to wonder who is behind them. Does anybody know anything about them? I usually tend to avoid customs like this, but as a BYU collector, I want to add some Zach Wilsons to my collection and the design of these don't look too bad, really. I'm seriously considering picking some up, just for fun.
