Re-punched Date
Definition: A repunched date is a date that has one or more numerals that have being repunched into a master or working die. This excludes doubled dies or re-engraved dates that show doubling on the digits of the date. This also excludes misplaced dates which is under a separate heading.
The above example of a repunched date is found on a 1 centavo from Colombia minted in 1969. The first two digits 19 have clearly been repunched.
