I got serial 00000081 a number of months ago but sold it on Ebay. I have serial 00000299 in my possession right now but it will be listed on Ebay next week. I personally don't collect these but know they sell for many times face value...so therefore I will certainly do that.
It went in the $60 to $70 range, and it was about EF condition. Actually I think the buyer expected it to go higher because he left me a message afterwards saying how he couldn't believe he got it for so cheap.
