Definition: An overdate affects a single working die. An overdate is created when one numeral is punched over a different numeral. If the second punch involves the same numeral, we call it a repunched date.
Overdates should not be confused with repunched dates, doubled dies, re-engraved dates, or misplaced dates. They should also not be confused with Class III double dies (design hub doubling). The latter also can result in overlapping, dissimilar numbers, but the process is entirely different. Class III doubled dies that result in overlapping, dissimilar numbers are sometimes called overdates, but this is not correct.
For U.S. coins, the overdate era ended in 1908. Beginning in 1909, the date was placed on the master hub or the master die. As a result, any claims of overdates later than 1908 must be greeted with extreme skepticism.
1958/7 and 1958/7 D Overdates? This Lincoln Cent variety exhibits what appears to be a 7 under the 8 of the date. The 1958 Doubled Die Obverse 1 is the rarest ddo in the Lincoln Cent series. Only two examples are known; a PCGS MS64RD and a PCGS MS65RD. Bold doubling can be seen on IN GOD WE TRUST, LIBERTY, and on the date. The coin pictured to the left is the MS64RD example.

1958 D Wheat Penny. CoinTrackers.com has estimated the 1958 D Wheat Penny value at an average of 15 cents, one in certified mint state (MS+) could be worth. The 1958 Doubled Die Obverse is the rarest and most valuable DDO error of all of the Lincoln Wheat Cent (Penny) series. There are only a handful known to exist and the coins are best identified by the very clear doubling of the legend 'IN GOD WE TRUST' and the doubling of the word 'LIBERTY' on the front of the coin.
This 1958-D Lincoln cent was once thought to be an overdate. A cluster of die gouges or die dents formed a pattern that resembles a partial 7 beneath the terminal 8.

Comments: Research by John Bordner, Billy G. Crawford, and John A. Wexler has led to the conclusion that this variety is a multiple punched D mint mark rather than a D/S mint mark as previously believed. Not all die variety specialists are in agreement and CONECA still lists the variety as an OMM (D/S). You need to judge and decide for yourself.
This image from Billy G. Crawford shows the key highpoints of what has been thought to be an underlying S mint mark. The marking at the lower left arrow is now believed to be part of an underlying D to the south. The top left arrow and the raised area inside the D are believed to be parts of an underlying horizontal D mint mark. The lower center and lower right arrows are consistent with either the horizontal D or the D to the south as will be seen in the following overlays from Billy G. Crawford.
This overlay from Billy G. Crawford shows a horizontal D overlay. Note how the highpoints of the upper left arrow and the two lower right arrows are a perfect match for what is seen on the supposed S. The lower left arrow also appears to match, but the shape is not right for what is seen at the point without the overlay. The element at the lower left arrow is believed to be part of an additional D punched to the south.
This overlay from Billy G. Crawford attempts to align an S with the key points indicated by arrows on the supposed D/S. Note that the bottom left and bottom right arrows do not coincide with the high points of the S.
Moving the S to coincide with the lower left and lower right arrows moves the S out of alignment with the upper left and lower center arrows.
This overlay from Billy G. Crawford shows how the bottom left arrow in the previous photos (#1 in this photo) matches a D/D South.

Comments: Research by John Bordner, Billy G. Crawford, and John A. Wexler has led to the conclusion that this variety is a repunched D mint mark rather than a D/S mint mark as previously believed. This variety was listed in the original The RPM Book as an RPM and an OMM. At some point later the listing was changed to an OMM (D/S) variety by CONECA. Not all die variety specialists are in agreement and CONECA still lists the variety as an OMM (D/S). You need to judge and decide for yourself.
This image courtesy of Billy G. Crawford shows keys points of the underlying mint mark that some believe to be an S mint mark.
This overlay from Billy G. Crawford shows that the secondary mint mark aligns perfectly with a D/D South.

Comments: This remarkable RPM variety has at the very least a very nice D/D Northwest. Not all die variety specialists agree that the other extra images are from a mint mark punch. The most interesting of these is an extra punch that is visible in the vest southwest of the date. It conforms perfectly to the upper left part of the D mint mark. A slight bulge protruding from the vest appears to be another punch. If all of the suspected markings are from the mint mark punch, there is a total of 5 impressions from the mint mark punch.
