So...is the beef that Green Arrow IS Selling, it's just that the comic store owners are making the money on $1 - 3 back issues and TPBs, but the speculators aren't pulling down coin?
I think the relatively complicated publication history can make it hard for people who don't know how to research these things to find a good starting point.
Which is where the New 52 comes in to it I guess.
I haven't seen a Green Arrow issue below #8 in bins around here in quite some time.
I buy #17 on the spot every time I see it.
And when I found 5 copies of Arrow #1 (The TV Show book) sitting in a dealer's forgotten box and brought them to his attention so he could maybe put them out where people could find them, he was really excited to see that he had some.
Pretty much every time I spend more than 5 minutes in a shop, someone brings up Green Arrow. You can find SO MUCH of it in dollar bins in almost any given comic shop though, that new fans haven't had to pay any kind of premium to get some decent books. If the show continues to be popular and it gets a few more seasons, I think you'll see modest buy steady increases in quality Green Arrow back issues.
