How to research an old stock certificate

SEC.gov -- Old Stock Certificates
http://www.sec.gov/answers/oldcer.htm
An old stock or bond certificate may still be valuable even if it no longer trades under the name printed on the certificate. The company may have merged with another company or simply changed its name. You can use the resources on this site if an old stock or bond certificate has value. Even if you learn that a certificate has no value, you may find that the certificate itself has value as a collectable.

The following two companies were suggested in the January 21, 2001 "Ask Dow Jones" newspaper column for people trying to find the value of old stock and bond certificates, as well as company histories such as name changes and mergers. These two sites provide only a description of their service, contact information and fee schedules. They do not provide the quotations online.
