Repunched Lettering (RPL)

Repunched Lettering occurs when design inscriptions on a coin die -- such as LIBERTY, E PLURIBUS UNUM, UNITED STATES OF AMERICA, or denomination text -- are punched more than once with slight misalignment between impressions. The result is letters that show traces of secondary positioning, appearing doubled, spread, or thickened compared to normally struck examples. RPL is the lettering equivalent of Repunched Mint Marks (RPMs) and Repunched Dates (RPDs), produced by the same hand-punching process that created those varieties.

What Is Repunched Lettering?

During certain periods of U.S. Mint history, individual letters and inscriptions were added to coin dies by hand. A die maker positioned a letter punch over the appropriate spot on the die face and struck it with a mallet. If the impression was insufficient or the positioning needed correction, the punch was struck again. Any misalignment between strikes left the die with two overlapping but offset impressions of the same letter, and every coin struck from that die reproduced the doubling. Error-Ref's definition covers any letter punched into a master or working die twice or more by accident.

RPL encompasses all repunched design text except the date (which is classified as RPD) and the mint mark (which is classified as RPM or DMM). The inscriptions affected include the national motto, the denomination, the country name, and the word LIBERTY -- essentially any text element that was hand-punched onto dies during the relevant production era.

RPL is distinct from Doubled Die varieties, where doubling results from hub misalignment during the die-making process. A doubled die shows on design elements that came from the hub, while RPL affects only the specific letters that were individually repunched. It is also distinct from die deterioration doubling, which comes from die wear rather than from punching.

How Does It Happen?

RPL varieties were created through the hand-punching process used for design lettering on coin dies:

• Letter-by-letter punching (to the mid-1830s): On early U.S. coins, only the central devices were hubbed; stars, legends, the denomination and the date were punched into each die by hand. Hubbing of the full design apart from the date arrived in the mid-to-late 1830s. A single die could require dozens of individual letter punches, and any of them could be repunched.
• Private dies: Tokens and store cards made by private die sinkers were lettered with hand punches as well. Error-Ref illustrates a repunched device, apparently initials, on an 1863 Civil War store card.

Once lettering was part of the hub, it was no longer punched into each working die, so later U.S. coins with fully hubbed designs do not produce RPL varieties in the same way. Apparent doubling of their lettering is usually a doubled die or mechanical doubling.

How to Identify Repunched Lettering

Detecting RPL requires systematic examination of each inscription on the coin:

• Scan all text elements: Check every letter in LIBERTY, E PLURIBUS UNUM, UNITED STATES OF AMERICA, and the denomination text (ONE CENT, for example). RPL can affect any inscription on either side of the coin.
• Look for doubled letter edges: The most visible RPL feature is a letter that shows two outlines. One edge of the letter appears doubled, with a secondary line or step visible alongside the primary impression.
• Check serif details: Letters with serifs (the small finishing strokes on letters like T, I, E, and L) show the clearest evidence of repunching. A repunched serif appears widened, split, or stepped. Compare suspect serifs to clearly normal letters elsewhere in the same inscription.
• Individual letter inconsistency: Because each letter was punched separately, different letters within the same word may show repunching in different directions or to different degrees, or not at all. Doubling that runs the same way across a whole inscription and the devices around it points to a doubled die instead.
• Use 10x to 20x magnification: Most RPL requires at least 10x magnification for detection. The letter dimensions on coins are small, and the displacement between punches is proportionally tiny.

RPL vs. Machine Doubling

Machine doubling takes several forms, and worn dies produce a look-alike of their own; Mechanical Doubling covers the whole family.

Machine doubling on lettering produces flat, shelf-like secondary images without the formed quality of genuine RPL. True RPL shows secondary letter impressions with the same depth, serif definition, and stroke quality as the primary letters. Machine doubling letters lack serifs on the displaced image and appear as thin, flat shelves alongside the primary impression.

RPL vs. Doubled Die

A doubled die shows its doubling on hubbed design elements because the doubling occurs at the hubbing stage. RPL affects only specific letters because the repunching occurred when individual punches were applied to the die. If the portrait and lettering show the same doubling, it is a doubled die. If only certain letters show repunching while the rest of the design is normal, and the coin is from the hand-punched era, it is RPL.

Notable Examples

Early Large Cents (1793 to the mid-1830s)

The lettering on early large cents, including LIBERTY and the reverse legends, was punched into each die by hand, so repunched letters belong to this series' die varieties. Early large cents are attributed die by die, and a repunched letter is part of a die's description.

Civil War Store Cards

Private die sinkers lettered their dies with hand punches. Error-Ref illustrates the 1863 Broas Brothers Pie Bakers store card, where what appear to be the designer's initials beneath a star show a secondary impression below and rotated from the first.

Collecting Tips

• Specialize in one inscription: Rather than searching for RPL across all text elements on all denominations, choose one inscription on one series and learn its normal appearance thoroughly. This focused approach produces better identification accuracy than broad, unfocused searching.
• Early coins offer the most variety: Coinage struck before full hubbing, with letter-by-letter punching, is where RPL belongs. Each letter on each die was an independent punching event, so a single die could contain several different RPL features across different inscriptions.
• Pair with other punch varieties: A die from the hand-punched era can carry repunched dates or other punch varieties alongside repunched lettering, because the same process applied the date and the legends.
• Photography for documentation: When you identify a potential RPL, photograph the affected letters at high magnification with oblique lighting. Clear documentation is essential for attribution, especially for varieties not yet cataloged in published references.
• Reference materials: Cross-reference suspected RPLs against the die-variety references for the series before submitting for professional attribution.
• Be wary of RPL claims on hubbed coins: On coins whose lettering was part of the hub, lettering that looks repunched is far more likely to be a doubled die or mechanical doubling.
