Yep, I got mine from an auction that didn't meet it's reserve on ebay. I was in contact with the seller throughout the auction and was going to buy it anyway. I payed just over the odds for it, but I was happy to considering how rare they are especially in England.
i think the highest price I've heard offered for a DEAD MINT one was $1000.
They do crop up every now and again, I think if you're serious about getting one, Rich might be able to track one down for you for a finders fee maybe? Either that or wait till one comes on ebay and ask theseller just how much it'll take for him to end that auction early, which isn't the most honorable of ways, but can be one of the most efficient.
