As the title says I am getting rid of my D&D 4e books. I just want to have an idea of what I should ask. They barely got used as real life prevented us from ever getting more than a handful of sessions in a single campaign. I have a list below of what I own. I want an idea in US dollars, as I live here.

The DMG/MM/PHB set
PHB2
PHB3
Adventurer's Vault 2
Heroes of the Forgotten Kingdoms (with Cavalier class)
& a PHB printed in B&W spiral bound

*The printed PHB isn't worth much I am sure, but I'd put it in there too. Not too attached to this edition.

Expect no more than half cover price for the books, depending on how/where you sell them.  In my experience the best sales times are right before major conventions and Christmas, tho you might get lucky with someone looking for those books at the time you post them.

In reply to Evil Empryss (msg # 2):

I'd likely want to sell them all to one person, unless they're only needing certain ones. I'll start there. Thanks Empryss

Fair warning: you may find selling them as a batch will be even more difficult, since most people who play the game already have at least some of the books.

I donated mine to Goodwill.

If you're looking for a feel-good donation, then take them to your nearest juvenile cancer ward and/or hospital.  Those kids need games to play that don't require a lot of physical activity and their families likely can't afford to buy them.

I really like this idea, good job Evil.
