The old adage really. You really don't know until you sell.
I own the #1 Registry Set for 1961 Fleer Signed Basketball (The Impossible Dream)

I have had 2 auction houses reach out in the past year and personally asked about selling this set. I think it will do fine but you really don't know until you pull the trigger tbh.
I also have the #6 1948 Bowman Basketball Set (thanks to a 2014 Vermont Find of pristine low numbers!) No idea if the position helps here. All I know is that my almost full set is the 3rd highest graded currently in the registry! (Top Shelf 1948 Bowman Hoops) Such a cute name huh? lol

I doubt any of that helped but good question nonetheless

. Thanks!
