Vrechek article on the 56 flat cap or cropping differences. There are a boatload of them. Can share list of those I have if interested. I think sliphorn ( Tom) may have the most extensive list of them

To your list I would add 261 Shants with the defective A in Athletics on the front, 292 Aparicio with white background and 321 Konstanty with some green stat boxes missing on back
Have only 2 cards from a Salesman Sample and only an unopened penny pack for 56. 56 and 58 Topps unopened packs are tough. Anthony ( Griffins) may have a full panel and a 5 cent pack . I do have a full Topps Hocus Focus baseball subset for 56
