for the most part i only collect coins, but i do have some notes. I was looking through some and noticed i have an uncirculated 1976 $2 bill. The serial number is 65030565. Would it be considered radar, or not because it has the one extra at the end.
if you want to check and see if you have a radar note, write the serial number backwards, start with the last number on to the first number, if the serial number is the same backwards as it is forwards it is a radar note. Your note is not a radar.
