 Many public libraries also have reference materials for old stock certificates. If all that fails and you have a brokerage account, you can ask your broker if they can help you determine the value of the certificates. Provide that QSEP number, that's C-U-S-I-P. You'll see that printed on the certificate, and hopefully they'll be able to help you. I think you'll get there. It may take some legwork, but thanks for writing to us. By the way, if you have a question, send it along, askrob at faithvine.com.
