Ball 756 is going to be branded with an asterisk and sent to Cooperstown.
Ecko's attention whoring notwithstanding, such an outcome seems like the most appropriate one in terms of reflecting the history of all of this. Shooting it into space would have been stupid. While my normal sensibility would be to let an historical artifact stand unadorned (I have been greatly disappointed by recent efforts of "interpretive centers" to deal with controversial issues) giving it to Cooperstown branded with an asterisk seems to capture this particular ball's uniquely historical nature.
There are a lot of milestone balls, and all of them more or less look the same. This one will stand out and, in its own way, more accurately reflect the time which produced it than a clean, but slightly scuffed ball ever could.
