I am not familer with paper bills, but I saw this serial number that intrigued me. Is this what is known as a radar serial number ?
No, its not a radar, due to presence of the other numbers. Were they 0000 in place of 9865, then you may be onto something. I personally don't go by 'partial' in the terminology though. Your note is also so thouroughly beat from circulation it negates any numismatic value beyond face. Check out this site for some radars and super radar examples.
