Brian E.Without a doubt the card is authentic. Red back Cobb cards, slabbed and in poor condition go for $225-$425. Overall, the condition doesn't look too bad and $375 is within reason. I would personally try to get it for $300-$350.
You need to see the reverse of the card, if the reverse is clean and there is not significant paper loss or markings, $300-$375 is okay on this card.
