<prompt> Human: Hey guys,So granpa has just passed. Turns out he bought about 50 or 60 shares of a company back in the 70s that is still around today. Only his 500 dollar investment did really well and is now working over 30 thousand dollars. Theses shares are the old fashioned kind issued on paper. Is there anyplace we can take these so we can sell them on the market? Or are they worthless?  <response>: GrandpaLike 30 grand, pa
