Why not include the actual players rookie cards sorted by rookie card year or debut? Who are the 8 players missing? Your idea is excellent. I'm just giving a few ways it can be improved uopn.

Thanks for support and feedback! Unfortunately a lot of the sets I do for fun are influenced by cost. With a daughter in college and getting married in 6 months and another in high school and in club sports I have to be discretionary in my spending if I want to remain married...😃 I would love to have the rookie MLB card of all former Negro league players....maybe some day! Regarding the 8 players I’ll need to go look at my list and reply back on those. Thanks again!

The 8 players in which I don't think a card exists are:

Pedro Dibut (Red Sox), Oscar Estrada (Red Sox), Vibert "Webbo" Clarke (Senators), Lino Donoso (Pirates), Izzy Leon (Phillies), Roberto Vargas (Braves), Charles Peete (Cardinals), Milt Smith (Reds).
