This is believed to be unique and has not been seen since lot 1594 of a 1938 B. Max Mehl sale. It is unknown if this coin really exists or is a misdescription. The Mehl sale coin is actually described as having the reverse of AW680 which is really the one used on J623/P692 which has "Cents" curved.
Note: It is very likely that the coin listed as J690/P766 is the same as either of these.
