<prompt> Human: Apologies if this is the wrong community for this I have paper stock certificates for Lehman Corporation and Salomon Brothers. Given what happened with these corporations in the last ten years, can these possibly be worth anything? If so, how can I redeem them? When I try googling how to redeem them I either get nothing at all or just some articles about Citigroup.  <response>: I know at one time Enron paper stock certificates were fetching a nice price just as a piece of history and reminder to investors.
