Mint-mark die varieties from the hand-punch era
Historical era notes and featured picks may still need specialist review. Counts are live from the catalog.
Repunched mint marks (RPMs) formed when a mint mark punch was impressed into a working die more than once in different positions or orientations. Collectors study the primary mint mark and any secondary images, plus die stages and markers.
Mint mark styles (punch profiles) are a different concept — they describe which punch was used, not whether it was repunched.
Die Search for MM also includes OM results by default.
RPMs differ from machine doubling, die chips, plating disturbance, damage, and photographic artifacts. Over mint marks (OMMs) are related but cataloged separately.
RPMs are not the same as:
Glossary: Repunched Mintmark · San Francisco S mintmark timeline · Beginner mint-mark step
Punch style matters for attribution and for understanding which mint-mark profile a die used. Styles are not RPMs.
Representative catalog dies. Editorial picks override the automatic list when set in CMS.

High-interest years
An RPM is a die variety where the mint mark punch was impressed more than once in different positions or orientations on the die, leaving a primary mint mark and one or more secondary images.
Traditional RPMs relate to the historical hand-punching of mint marks into working dies. Do not assume modern machine-applied mint marks create the same class of variety. See year pages and mint-mark style notes for era context.
No. Mint mark styles describe punch profiles (for example serif S vs. Clear-S). An RPM is a die variety from multiple impressions of a mint mark on one die.
Over mint marks are cataloged separately (die type OM). They are related mint-mark die varieties and appear alongside RPMs in some CopperCoins searches.
