This set really needs to be worked on. "Depending on how you look at it, the 2014 Panini Hall of Fame 75th Anniversary Baseball checklist has either 100 cards or 300 cards. There are 100 players. Each has a regular card and a pair of variations. Chasing all will be a challenge as base cards are numbered to just 75 copies." With that said, we should change the base set to have an a, b, and c variation for each card. Base 1 or (A) would have the Green frame, Base 2 or (B) would have the Blue frame, and Base 3 or (C) would have the Red frame. Each parallel of the three colored frames are all SN the same (Black SN1, Blue SN25, Gold SN5, Green SN10, Red SN50). Each parallel should also have an a, b, and c variation as well.
