I've played this character for about two years, he's the only D&D character I've ever played, and our campaign just ended. I won't be playing him again.

I'm not all that familiar with D&D, and almost all of these items were rewards for completed quests, or looted treasure. I don't know their monetary value. So I'm wondering, if this character sold all his stuff, how much money could he make? Is it enough to live comfortably?
