A few boring but important things.
Pigskin Portfolio is independent. We are not affiliated with Topps, Bowman or Fanatics. Those names are used because those are the cards we research.
Some eBay links are affiliate links. If you buy something after clicking one, Pigskin Portfolio may earn a commission at no extra cost to you. That does not change which players we rank or what grade they receive.
Pigskin Prospect Grade combines football upside, production, hobby position, class runway, modeled individual recognition and verified Bowman significance. It is not a card price target, an NFL Draft prediction or a promise that a card will go up.
A serial number tells you how many copies exist of that specific numbered version. It is not the same thing as a total product print run.
The public 1st Bowman index only publishes resolved calls. Momentum is only published when there is a real before-and-after to measure.
