<prompt> Human: Found a stock from 77 in my deceased parents things. There are other stocks I dont have a pic handy of. Figured one at a time. My Mothers final bills are piling on so maybe this can help? My bestys husband recommended posting here to learn more. What do I do with it? How? How do I ascertain its worth? Stock from the 70s... What do I do with it and how?  <response>: Frame it? Its one share of what appears to be a small co-op. It has no value.
