2010-11 Panini Gold Standard Gold Mining #20 LeBron James 14K Gold 5/8 BGS NM-MT+ 8.5. Part of Panini's premium Gold Standard series - which came in one 12-card pack/box for $200 - this is from the Gold Mining subset with LeBron's being the last of the 20-card set, with an extremely limited print run of just eight (8). Strong 8.5 overall grade with subs of: Centering 8.5, Corners 9, Edges 9, Surface 8.5. Giving new meaning to the phrase "worth its weight in gold," but style and substance combine for an exceptional and rare offering.
