+1. I have a 500 HR display of basically the 11 living members back in the day. Stored in the same ball cubes, beside each other in a cabinet. These balls were collected through signings advertised in SCD. Two of them (Robinson and Killebrew) eventually "dissipate(d) into nothing visually". The remaining seemed unchanged.

Note: I managed to replace the balls through Net54 BST. My notation of a successful transaction is below.
