I purchased my first original page off of eBay for $130. At the time the book it was published in was a $30-$40 book. Since then I couldn't justify spending money on a mass produced comic that could, instead, get me a one of a kind page. Sure, my collection is mostly junk, but it's one of a kind junk
I still have several long boxes of comics. After I read them and I don't think they are going to get a re-read and aren't worth the space to store them they either go on eBay (if they are worth shipping) or sold at a local auction house where no one knows a damn thing about comics.
