How much???
 

How much would a Beckett Graded 1 Ty Cobb Red Background go for?

what kind of back?
 

because auth, poor, fair & good values can be all over the board, it's difficult to assess without a scan...
an accurate "ballpark" number would be $300.

For grade Poor T206s, including the Honus Wagner, eye appeal has great influence on value. Strong eye appeal can add $100,000+ to the value of a grade Poor Wagner.

Red Cobb
 

I'd say $300-$375 for BVG 1 graded Cobb.

$350 or so, maybe a little more for one with really strong eye appeal.
