Answered, thanks
 

Hi gang,

These feel thinner, more fragile than a standard t206 and the backs are smooth, not coarse as if their backs were skinned (my first thought).

Anyone familiar with this issue and/or value please?

E97?

Those are E97 black and whites. They haven't been skinned. They're blank backed and thin stock.

They're worth a couple hundred to several hundred bucks a piece.

Nice cards.

Rob

much obliged fellas.
