Sharp Zero - 10040 Hyndman Rd - Mountain Ont. - K0E 1S0I also research US certificates. Just send a photocopy of the certificates (maximum of 3 please) and a cheque for $40 USD to the same address. Please include a stamped, self-addressed envelope -- I will either write back with the results of my research or return your cheque if I couldn't turn anything up on any of the certificates. You can also email a scan of the certificates to email@example.com and simply send the cheque by mail (so I can get started right away). Make sure the scans are readable since the markings may be helpful. Note that in many cases, the company charters will simply have been cancelled. Either way, I'll provide the details. No charge if I can't dig anything up at all on any of your certificates. In many cases the certificates may be worth something -- but your journey has only just begun since you will have to get a broker to accept them -- for example, if a certificate is in the name of a deceased person, you will have to produce some documentation to prove that it now belongs to you.
