1934 graded Gehrig on Ebay
 

There is a PSA 3.5 Gehrig up now for $950, but it seems to have the same item number as one the same seller sold on October 14. I looked at completed auctions and he also appears to have sold two PSA 5 graded Ruth's within a day of each other also with the same item number in October.

Do the cards look legitimate? Am I missing something about the way PSA numbers items?
