I have a box of old lightbulbs, Edison Mazada and others in that time frame I think, some pretty good sized ones too. Some with packaging and some not, that my dad had. Is there a decent reliable source to find out their value. I am not sure if I should keep them, if they are worth it, donate them to the local Museum because it has a big Edison exihbit, sell them, or use them for target practice because they are not worth keeping, lol.
Thanks in advance.
