I'd like to try a little experiment.
I own a Series 1 Casascius coin, the kind that has a misprint on it. There were less than a thousand of these made, so they are very rare. You can view my precious here:

I will post a video of the process; I'm thinking I'll start by burning the holographic sticker and finish by melting down the brass into a pool of golden oblivion on my stove. I'm open to suggestion on how to destroy it, feel free to recommend something more creative (I do have one of those latex horse masks now that I think about it).
Instead of a typical auction, this will be done as a crowdfunded project! I'd like John K to manage the process as escrow. If he is willing, instead of the typical 2% fee I would like him to take 1% and have the other 1% donated to the bitcoin forums. So I have some skin in the donation game as well, I will donate another 1% to the Bitcoin Foundation or whatever you guys vote for the most. If John K doesn't work out but there is still interest in this experiment, I will figure out another way.
This crowdfunding experiment is to end Sunday, May 5 at midnight GMT. The goal is 10 BTC, with anything less being refunded back to participants. Escrow and donation fees will be deducted from the final result. Remember, this destroys the coin forever!
