Can anyone tell me what these are?

They can be PC or blank back.

I like a lot of different cards but these don't really do it for me (not that anyone asked).

I would say maybe early 1960s.

Adam, was pretty sure they came with both backs but not positive.

I can confirm these come with both printed PC backs and blank backs. I have both sets.
