I have Dio's 1953, first year of production Gibson bass from his estate on which he wrote and demo'd songs. I am the first owner since it left his estate and I've only played it once. It was framed and consigned to a Ceasars Palace Forum shop in Las Vegas for 18K. I have a sizeable collection of his possessions I'm disposing of. Asking 13K for the EB-1, unmounted and in original case.
