I’ve been going through my old collection and pulling out the issues I’d like to sell—but I don’t know where to get an estimate of the going price for each issue, much less how to go about selling them.

For my purposes, these “old comics” are mainly from the mid-80s and early 90s, titles like Suicide Squad, Punisher War Journal, Ninja High School (oh gawd I actually bought that) as well as random issues of Spider-Man, Legion of Super-Heroes, and Marvel’s New Universe (if anyone remembers that).

The simplest way to sell these would be at a yard sale, but that would probably mean getting the least possible value and I likely wouldn’t sell too many. Can anyone suggest a better way to sell them, and a reliable source for current prices?
