<prompt> Human: I have a sizeable amount of Exxon mobile shares that are in my grandmothers name and held by a company called compushare. I have the original papers shares that are stamped from 1968. How do I go about claiming ownership? I am the sole trustee of my grandmothers will. When I went to the compushare company they said I needed a medallion stamped on their form and the banks dont do the medallion stamps anymore. I need some help as Im pretty lost in this subject.Assistant: Thanks for the reply. None of the banks will give me the medallion because I dont have accounts there. My bank, bank of America has cancelled the medallion signature guarantee program.  <response>: What are you going to do with the shares? Are you going to transfer them to a brokerage account or sell them and take the cash?If youre keeping them, the company you want to transfer them to will help with the medallion. If youre cashing them out, you can put the proceeds in an account at a bank that has the medallion available.Its still a pretty common thing -- you just need to do the legwork.
