  2. Misplaced Dates (MPD's)

    Misplaced Dates (MPD's) are coins which have dates or digits of the date in area of the coin where it is not supposed to be. Misplaced Dates can be seen in the denticles of the coin as well as on some of the devices of the coin as well. It is unclear whether this variety was created, one theory being it was done as a hardness test if a misplaced date was toward the middle of the die or a gross error in aligning the date prior to punching the date onto the working die. Please add your comments or questions about Misplaced Dates within this forum.

  3. Overdates

    Overdates on coins are created when the mint repurposes a working die from another year. They attempt to fill in the old year on the die. Then stamp a new single or double digit into this die. Overdate coins can be very dramatic and very noticeable or very close and subtle. This area is for questions and comments on coins with overdates.

  4. Re-Punched Dates (RPD's)

    Back in the day, Each die that was created had its date punched into the die by hand. They softened up the die and then utilizing a date punch and maybe a mallet attempted to strike the date into the new die. This process was far from perfect. Some times the punching of the date was insufficient and additional attempts to add good date was done. Re-punched dates can be either very dramatic in nature or very close and subtle. This area is open for discussions and questions about the Repunched date variety.

  5. Re-Punched Mintmarks (RPM's)

    In the United States, Repunched Mintmarks (RPM's) existed until the 1990's. It was then that manual process of adding a mintmark to a working die ceased. Repunched Mintmarks are common amongst collectors. Feel free to post a comment or any questions related to RPM's within this forum

  6. Over Mint Marks (OMM's)

    Over Mint Marks (OMM's) occur when the mint either repurposes a die or makes a mistake. The mint will eventually have two different mint marks on one working die. The process was to place one mint mark over the top of another. In some instances this was a D over an S, an S over a D, an O over a CC or other such combinations. Another subcategory here is the use of Double Mint Marks (DMM's). This occurred when two mint marks were added in different areas of the coin and no attempt was done to cover them up. In this forum please feel free to ask questions or post a comment on Over Mint Mark coins and Double Mint Mark coins.

  7. Inverted Mint Marks (IMM's)

    Inverted Mint Marks (IMM's) occurred when a punch was used to add a mint mark into a working die, but that punch was held upside-down. The die was then added to a machine which created coins with the inverted mint mark.  Please add your comments and questions about Inverted Mint Marks here.
