I think I signed up for the board many years ago and posted here and there. But I just started reading/posting with more frequency the past couple of weeks.
I collect romance comics, Silver Age and up from Marvel and DCs (FF, Daredevil, Dr. Strange, Flash, JLA, Atom, Titans, "cosmic stuff"), as well as a smattering of other odds and ends.
I have a nice collection of 1950s romance original art, as well.
I had a pretty decent collection of Quality and Fawcett hero books, but I sold most around 5 years ago to pay down debt before my son was born. (I think there is no better value in Golden Age books based on quality of story/art than early Quality Comics... You can get early Hit/Crack/Smash/etc for a fraction the cost of DCs and Timelys... But I digress...)
I tend to collect lower grades, because I'd rather have quantity of comics over quality of grade.
I've also started selling more on eBay, where I've focused mostly on Copper and Modern, with a smattering of Silver and Gold.
