This forum isn't the best place to ask the question. The people who post here, for the most part, are more focused on older (truly rare) vintage pieces and not modern "created" pieces like the one you're describing.
I'm sure there are many collectors out there that would go gaga for all the "perfect 10" graded signatures and multiple LOAs that accompany your Ball. But they would most likely tend to frequent forums/venues other than this one.
It's admittedly kinda snooty around here, as this forum isn't the best place to discuss new/modern collectibles like your piece. That said... Steiner's prices are borderline insane, and if you get even close to what you paid for it, you've done exceedingly well
