1928 Ty Cobb Harringtion - Need Help!!!
 

I am adding to my Yankee collection and have decided to part with my 1928 Harrington Ty Cobb PSA 6. It is the highest graded Cobb and only 8 have ever been graded (1 PSA 3, 4 PSA 4, 2 PSA 5, and 1 PSA 6). I see the Ruths for sale at lower grades and there are 25 of them graded by PSA. Obviously, my question is what do you think I can expect to get for this card. Thanks for any help you can give.....
