I don't have this variety, but I collect repunched dates and overdates from many mints.
To my eyes, there would have to be at least 2 digits underneath--one punched slightly higher, only showing inside the loop, and another punched below at a greater distance. Usually, a large portion of the underlying date is polished away, leaving only traces of the older digits.
