1957-D DDO?

That would be 1989 on the RPMs...not 1990.

Depends on the denomination. Indian cents for example used what was called a "Gang punch" of the four digit date and that punch was used to add dates to a die. I know, for example that they were used at least until 1908 on IHCents as there are repunched date examples for that year. I am not sure how it was done in 1909 as I am not sure if there are any RPD coins for that year. So on Indian Head cents for example Repunched dates can occur at least to 1908 and someone else may be able to add 1909 to the list. That date is beyond my knowledge.

Some coins like the Liberty Head Nickel for example used (in many years) a punch with three digits and then a final number so an 1897 for example would have used one punch for the 189 and another punch for the final digit. For the same year, it is also known that a four digit punch was used that included the 7. In any case, repunched dates can be found in that series. When they stopped punching dates in by hand with Liberty nickels, I don't know exactly. I do know of examples of repunched dates until 1899. There could be later ones, I am not sure.

Later coinage had the dates on the hubs which then made the dies. So Buffalo nickels for example would not have had the dates punched in to the dies by hand. Nor would Lincoln cents, Winged Liberty head dimes, Standing Lib quarters etc. This also means that there is no such thing as a Lincoln Cent with a repunched date.

Modern overdates, like the 1942/1 dimes involved two hubs, each with the dates already on them (One dated 1942 and the other 1941) then used to create a die.

So they are not repunched dates.

Doubled dates on modern series of coins are due to dies being doubled and not dates or numerals being punched into the dies.
