This was discussed not too long ago. I believe the general consensus was that i the provenance might help with confidence that the card hasn't been altered. In those cases, it would bring at least strong values, if not a bit of a premium. However, the BSF had a very different impact on the hobby. You essentially took what used to be a fairly rare and condition sensitive set and flooded the market with a ton of high grade cards. In my opinion, the BSF E98s are awesome and allow collectors to get their hands on some high grade examples of some of the best images for the time. But, the BSF had a significant negative impact on the values of E98s, considering the high grades of the find.
