Kevin"SO would you think all t206 blank backed cards are unique?"
They can be.

as shown before.
Question:
How about blank fronts, do you think they would sell for a premium? It can be player you want...could be a Cobb...could be a Wagner etc.
Singing to the choir?
Check it's authenticity by putting it under a fluorescent black or UV light. Best if it's completely dark and high watt. Fish tank hoods built into an open front wood box (black-light box) work great! If you are serious about card collecting, it’s a must have item.
As an example, I would not be comfortable with the blank back Jennings that was sold a few days ago. Scanners, at times, can produce an image that looks like it's under a black-light.
