 Let me tell you, Jared, first, you just want to check to see, is the company still traded on a stock exchange? You can do this at many major financial websites. You can also try to contact the certificate transfer agent, which should be listed on the certificate itself. Now, if the transfer agent no longer exists, you'll want to contact the state agency that handles incorporation where the company was established. That office may provide a way to search online for information on that company.
