It's home cleaning time, and I'm staring at several shelves of comics, mostly DC Vertigo, bought 1991-1998 or thereabouts. I haven't looked at them in years; it's time for them to go. I'm afraid that, if I walk into a comic store with buckets of comics, that I'll be offered some insanely low price for them. What are these things actually worth? What's the right way to sell them?

Google didn't turn up very much in the way of useful information. eBay has a couple auctions on these sorts of comics, and they tend to be going for roughly $1/each, at least for the more popular titles like Sandman. Thoughts anyone?
