I hate this thread. I've been avoiding it. It's just too painful.
I was buying comics in the early '60s. They were 10 cents then went up to 12 cents each. I favored DC over Marvel but bought some of both. My favorites were the JLA and Green Lantern. They were in boxes in my parent's basement when I was in college and then got my first apartment. My Mom saw them and donated a lot of them to the local grade school one year for their Halloween carnival, where they wrapped them in groups and sold them as part of the $1 grab bag prizes. I did not find out about this until after they were long gone, when I went looking for them and my Mom told me what she'd done with them. I still loved my Mom anyway, of course.
But that's not why I hate this thread. I bought one comic in 1962 for 12 cents and felt pretty good years later when I sold it for a hundred dollars. That mistake will continue to hurt me the rest of my life. The comic was The Amazing Spider-Man number one.
