I have a blue seal Silver Certificate and want to know if it is worth anything. It is in VG condition, it is series 1957.B. Serial Number W85058055A Granshan & Dillon. It also has E780 on it if that means anything to you. Hopefully I have included everything that you need to figure out the value of my certificate and can't wait to hear from you soon. If it is worth anything, other than the dollar that it shows, how do I go about getting the money for it? I don't know... I am sooo confused. Thank you for your help.
