How to determine gallery pricing for art prints?

I’m getting ready to show one of my pieces in a group gallery show. It’s my first time doing something like this and I have no idea how to price the piece. See http://www.davestolte.com for an idea of what I do – the print is a limited edition, one of one hundred. It’s a high-quality fine-art print on acid-free paper using archival inks. I’m framing & matting as well, in a nice simple black wood deep-set frame.

If location matters, I’m in Southern California but not Los Angeles.

Anyone with gallery experience have an idea of a ballpark price range?
