As mentioned above, pictures are needed. However, cutting errors in paper money generally have little or no value since a person can start with an uncut sheet of currency (available from the BEP) and create all of the cutting "errors" that they wish.
The original thread that bowhunterj9 posted the pics of the miscut note was in his introduction; http://www.cointalk.com/t116606/ I've copied his pic and posted it here:
Checked the BEP website and it doesn't fall under the serial numbers as being sold as an uncut sheet.
I've been trying to find something similar that's been sold recently but no luck yet. Be patient. I'm sure someone can help.
You can poke around on USARARE Error Currency for examples that may be similar to your cutting error. Not saying you will find the same or similar or a different section of your sheet from the print run, but you can get an idea from there about such notes, premiums, etc.
Providing this is a genuine error, it may be worth a very nice premium. I would like to see larger images so I can more carefully examine the note.. front and rear please. RickieB
I was not aware that $20's were sold in sheets. Must be something new. In the past, ones and twos were sold that way, and it absolutely destroyed cutting error market for those denominations, (as it should).
