First Post Here, and Trying to Find Value of 1928 W502 Ty Cobb Blank Back PSA 5.5
 

Hi all. I do a lot of business in modern cards, but very little in vintage. I recently acquired a 1928 W502 Blank Back Ty Cobb. I sent it to PSA and the grade popped last night and it's an Excellent + 5.5.

It's the highest graded blank back PSA has had. The previous was a PSA 4 (which recently sold for $780) and I'm trying to figure out what a practical value is on my 5.5. If anyone can try to help me, I would greatly appreciate it.


EDIT: I did get one response showing that the Babe Ruth PSA 5 sold for $1573 and the PSA 5.5 Babe Ruth sold for $2130. A PSA 4 Ruth sold for $1050 as well. There is a PSA 6 Ruth in the pop report, but no sales listed on it.
