Right now we only know the serial # of the note in the news, (if you have a serial please do post it). We cannot determine if this is a sheet error, or multiple sheet error. If a price is established, then this would have to reflect an Unc note, and then the condition of the note would determine the sale value of the note for sale.
It is important to realize that this error note has had allot of attention, and thus creating a false market demand. What I mean, people might be thinking it is worth more then it really is, and yes I know, it is worth the price someone will pay for it, but would the seller pay you that amount for the same item. The market can temporally over-inflate the price creating a false value for the note, and then crashing. This is the case of jumping on the bandwagon for the hot stock.
So lets make-up a price, $20 x 1000%(great ROI) = $220 for UNC
For one thing, and this is my option, this is not the Holy Grail of bank notes as stated in the news story. I am sure we can all think of a rarer note.
That's my two cents
