Seth Godin recently had an interesting blog post about charity auctions that I discussed on the OYFP blog - basically his point was that the goal of such auctions is to get people to pay MORE than what it's worth.
I can't speak for a doodle auction, though I always like clever ideas that are a little outside of the box. I've had photographs included in charity auctions for Kick for NIck - I think the winner paid about what it was worth ($30) considering it wasn't framed and I'm not a professional who typically sells her work. Maybe next time someone will go nuts and way over-bid. :-)
