Vintage Card Prices check on golf & boxing

I hear a lot about this service and was wondering if they have comprehensive results about golf and boxing also. For instance, what about a 1928 Ogden's Jack Dempsey in PSA 6 or a 1930 Drapkin Bobby Jones in PSA 5? Can someone give me recent sales for these 2 cards? Thanks, Tom

as for the Dempsey again nothing changed hands in a PSA 6 but a 7 was sold for 153.51 on August 4/07, a PSA 4 was sold for 34.01 on December 18, 2006 and a PSA 8 went for 610.00 on Ebay on April 25, 2007.
Hope that helps.
