Oh, and a couple of traps that people often overlook when thinking about selling comics. Grade is everything with hardcore comic collectors. There's a whole business devoted to it, CGC. Condition defects aren't just a minor hit in what they'll pay for it, bad condition can actually take it down to pennies on the dollar. And smart collectors almost never pay guide, those tend to be overvalued. Best way to find out what people will really pay for something is to grade accurately, then go to eBay and check completed listings for that grade. Based on that I found a Flash 250 in NM, that means it looks like the day it came off the newstand, that sold for $8. Lesser copies are going for one to three dollars.
