This is a Series 1977 $20.00 note with a nice gutter fold. The note has seen circulation but nothing real distracting. The serial number has been affected by the food but it’s still readable. The serial number, while not fancy, is a nest number and adds to the bill. The serial number is C12123993 B. The first four digits are a 2 digit repeater and the last four numbers are a radar.
Very nice, if it is a circulation find you have done better than me I have never found a currency error
