72 old baseball cards “the A’s”

I was going through my grandmother‘s attic and we found some of my late father old baseball cards from when he was younger I think there’s 72 of them give or take one. They’re all the same team they are made out of cardboard instead of what they usually are made out of now take that consideration. I’ve never seen a cardboard playing card before there’s another listing on my page of another binder we found of his cards (sold)but these were separated in there own box so I’m selling separated) I also show a photo of a front and back as an example of the card to show that it’s like brown they are from the 80s
