I posted this in a different section since I didn't realize that there was a paper money forum. http://www.cointalk.com/t152754/ Any guess on worth and rareness?
What you would get for it is 50 bux. If a dealer had it, retail would probably be 55-60 bux, as a guess. I could be wrong. Try to eBay it... You might be plesantly surprised if the right set of bidders see it. Certainly couldn't hurt so long as you get 50 bux for it.
If you followed the link, you'd have known it was extensively discussed previously. Fifty was clearly bored with nothing of any value to add to this and revived a pointless repeat thread. Check the other thread instead of this one.
