The Hidden History Behind Coins Used in Coin-Operated Machines: From Buffalo Nickels to Clad Quarters
May 7, 2026The Buyer’s Mindset: Why Collectors Overpay for 1776-2026 Pennies — A Behavioral Economist’s Deep Dive into Numismatic Desire
May 7, 2026To truly appreciate this piece, we need to step into the shoes of the artist who created it — and the political minefield they navigated with every chisel stroke.
Introduction: The Allure of the Unexplained
I’ve spent the better part of my career as a numismatic historian examining coins under magnification, and I can tell you that thousands of them have passed across my desk. Yet nothing fires up the imagination quite like a coin that flat-out defies easy explanation. Recently, a thread popped up on one of the major collecting forums that perfectly captures the tension we all know too well — the tug-of-war between a genuine mint error and a post-mint alteration. The thread was titled “One of One? Or, PMD?” and it centered on a 1963-D Lincoln cent bearing mysterious raised symbols on both sides. What started as a straightforward authentication question quickly evolved into a masterclass in minting science, die preparation, and the critical importance of understanding how Chief Engravers and their teams operated under the political and technical constraints of the United States Mint.
In this piece, I want to use that forum discussion as a springboard to explore the broader world of mint engravers — their artistic influences, their rejected designs, and the internal politics that shaped the very coins we collect today. Whether you’re a seasoned numismatist or just getting your feet wet, understanding the human story behind every die strike will fundamentally change the way you evaluate unusual pieces.
The Forum Mystery: A 1963-D Cent with Raised Symbols
The original poster, a collector who goes by the handle newbuddy56258, presented a 1963-D Lincoln cent bearing a raised metal symbol — resembling an ampersand (&) — on both the obverse and reverse. The collector’s gut instinct was post-mint damage, or PMD. But under high magnification, something didn’t add up. There was no visible evidence of depressed surface area surrounding the raised image, the kind of collateral disruption you’d typically expect from a counter-punch hammered into the coin after it left the mint.
That observation is critical, and it’s where the story becomes genuinely instructive for collectors at every level. The collector put it plainly:
“If this is PMD, then why is there no visible evidence of metal impression surrounding the image?”
Excellent question. It cuts right to the heart of how metal behaves under force. Let me walk you through the technical details that the forum’s sharpest members laid out, and then expand on the historical context that makes this whole discussion so much richer.
Understanding the Minting Process: How Dies Create Coins
Before you can evaluate whether a mark on a coin originated at the mint or after the fact, you need to understand the fundamental mechanics of how a coin is struck. This is where the artistry of the Chief Engraver meets the industrial precision of the minting floor.
The Role of the Chief Engraver
The Chief Engraver of the United States Mint holds one of the most quietly influential positions in American art history. This person designs and prepares the master dies from which all working dies are produced. The role has been held by some of the most talented artists this country has ever produced:
- James B. Longacre (1844–1869) — Designer of the Indian Head cent and the Shield nickel
- Charles E. Barber (1879–1917) — Designer of the Barber coinage, whose conservative style drew both praise and sharp criticism
- John R. Sinnock (1925–1947) — Designer of the Roosevelt dime and the Franklin half dollar
- Gilroy Roberts (1948–1964) — Designer of the obverse of the Kennedy half dollar
- Frank Gasparro (1965–1981) — Designer of the Eisenhower dollar and the Susan B. Anthony dollar
Each of these engravers worked inside a complex web of artistic tradition, political pressure, and technical limitation. The Lincoln Memorial reverse on the 1963-D cent in question was designed by Frank Gasparro, the ninth Chief Engraver. His design replaced the iconic wheat ears reverse that had been in use since 1909, and the transition was not without controversy. Gasparro himself reportedly had mixed feelings about the final product, and the shift from wheat to Memorial involved significant internal debate at the Mint.
How a Die Creates a Coin’s Surface
When a coin is struck, the blank planchet is pressed between two hardened steel dies at tremendous pressure — typically between 30 and 100 tons, depending on the denomination. The design on the die is incuse, meaning it’s sunken into the die’s surface. That means the resulting coin shows the design in relief, raised above the coin’s field. This is a fundamental principle every collector must internalize:
- An incuse mark on a die creates a raised mark on the coin
- A raised mark on a die creates an incuse (sunken) mark on the coin
This principle was central to the forum discussion. As one experienced member, Sapyx, explained with admirable clarity:
“If the mint were to deliberately damage or deface a die because it failed an inspection, it would simply be destroyed; they wouldn’t carve ampersands on it and then strike coins with it. And if, hypothetically it did happen, then a ‘mark’ carved or stamped onto a die would create a raised mark on the coin, not an indented one.”
Absolutely correct. It reflects the rigorous quality control protocols that have governed die preparation at the U.S. Mint for over two centuries. Dies that fail inspection are destroyed — not marked, not repurposed, and certainly not used to strike coins for circulation.
The Counter-Punch Technique: How PMD Can Mimic Mint Errors
One of the most illuminating threads in the entire forum discussion was the detailed breakdown of how a counter-punch — a tool used to stamp a design into metal — can create marks that superficially resemble genuine mint errors.
The Physics of a Counter-Punch
When a punch is driven into a coin’s surface with a hammer, the force displaces metal downward and outward. As Sapyx noted:
“A well-braced punch applies downwards force only on the area directly underneath the punch. This will displace the metal, but downwards, pushing ‘out’ the metal on the opposite side of the coin.”
So if you punch a design into the obverse, you’ll see a corresponding raised or flattened area on the reverse. That’s exactly what forum members observed on the 1963-D cent — a flattened spot on the Memorial reverse, directly opposite the symbol on Lincoln’s portrait. It’s a telltale sign of post-mint alteration, and one of the most reliable diagnostic tools available to collectors evaluating unusual pieces.
Why the Absence of Surrounding Damage Can Be Misleading
The original poster was puzzled by the lack of visible depressed surface area around the raised symbols. I understand the confusion — it’s a common stumbling block. A skilled hand using a sharp, well-maintained punch on a properly braced coin can produce a remarkably clean impression with minimal collateral damage. The key factors are:
- Punch quality — A sharp, clean punch with a well-defined design produces a far cleaner impression than a worn or damaged one
- Bracing — Place the coin on a hard, flat surface before striking, and the metal has nowhere to go but into the punch’s negative space, creating a raised image with minimal surrounding distortion
- Force control — A single, decisive blow is far more likely to produce a clean impression than multiple tentative strikes
- Coin composition — The 1963-D cent is bronze (95% copper, 5% zinc), which is relatively soft and accepts impressions more readily than harder alloys
Another forum member, JBK, offered an alternative method worth noting:
“Punch a letter into soft steel, place the coin over the punched area, place a somewhat soft material such as a piece of wood on the coin and strike it with a hammer. The force will drive the coin’s surface into the punched design.”
This technique — essentially using a die-like setup to impress a design into a finished coin — can produce raised symbols that are remarkably difficult to distinguish from genuine mint marks without careful examination. It’s a testament to the ingenuity of those who alter coins, and it underscores why collectors need to understand the full range of post-mint alteration techniques out there.
Mint Politics and Die Inspection: Separating Fact from Fiction
One of the most persistent myths in numismatics is the idea that mint employees sometimes mark dies for inspection purposes, and that coins bearing these marks occasionally slip into circulation. The original poster floated this theory, and it deserves a direct response.
The Reality of Die Inspection Protocols
The United States Mint has maintained rigorous die inspection protocols since the early 19th century. Dies are inspected at multiple stages of production:
- After hubbing — The initial impression from the master die is inspected for completeness and quality
- After finishing — Hand-engraved details and final touches are verified
- After heat treatment — The hardened die is inspected for cracks, warping, or other defects
- Before being placed into service — A final inspection ensures the die meets all specifications
Dies that fail any of these inspections are destroyed. They are not marked, not set aside, and not used to strike coins. The notion that a mint employee would carve an ampersand or any other symbol into a die and then run coins with it is, as Sapyx correctly stated, simply not how the Mint operates. Full stop.
The Political Climate of Mid-Century Mint Engraving
The early 1960s were a period of significant upheaval at the U.S. Mint. Frank Gasparro had recently stepped into the role of Chief Engraver following Gilroy Roberts’s death, and the Mint was under considerable pressure to modernize its coinage designs. The transition from the wheat reverse to the Memorial reverse on the Lincoln cent in 1959 had been controversial, and Gasparro was navigating a complex political landscape that included:
- Congressional oversight — Coinage designs required approval from the Treasury Secretary and, in some cases, Congress itself
- Public sentiment — The Lincoln cent was — and remains — one of the most widely circulated and emotionally resonant coins in American history
- Technical constraints — The Mint was transitioning from older, manual die-making techniques to newer, more automated processes
- Internal politics — The relationship between the Chief Engraver and the Mint Director was often fraught, as artistic vision clashed with bureaucratic priorities
Grasping this context is essential for collectors evaluating unusual coins from this era. The political and technical pressures on Mint engravers were immense. The result was a period of remarkable creativity — but also one in which quality control was absolutely paramount. The idea that a die bearing an unauthorized symbol would pass through multiple layers of inspection and enter production is, frankly, implausible.
Rejected Designs and the Engraver’s Dilemma
One of the most fascinating corners of numismatic history is the story of designs that never made it to production. Chief Engravers throughout history have submitted designs that were rejected for political, aesthetic, or technical reasons, and these rejected designs offer a rare window into the creative process that shaped our coinage.
Frank Gasparro’s Rejected Designs
Frank Gasparro, who was serving as Chief Engraver when the 1963-D cent was produced, was a prolific designer whose work spanned decades. Among his notable rejected or modified designs were:
- The original Kennedy half dollar reverse — Gasparro’s initial design was modified at Jacqueline Kennedy’s request
- Early concepts for the Eisenhower dollar — Multiple iterations were considered before the final design earned approval
- Alternative Lincoln Memorial reverse concepts — Gasparro explored several approaches before settling on the design we know today
These rejected designs are a powerful reminder that every coin in your collection represents a series of artistic and political compromises. The engraver’s vision is always mediated by external forces — from the hardness of the steel in the die to the preferences of the Treasury Secretary.
The Artistic Influences on Mid-Century Coin Design
The 1960s were a period of significant artistic ferment in American culture, and that energy found its way into coin design. Gasparro and his contemporaries were influenced by:
- The modernist movement — Clean lines, simplified forms, and a deliberate rejection of Victorian ornamentation
- The space race — A fascination with technology and progress that shaped the design of commemorative issues
- Classical revival — A renewed interest in Greco-Roman artistic traditions, particularly in commemorative medal design
- Political symbolism — The Cold War context meant American coinage was often designed to project strength, stability, and democratic values
These influences shaped not only the designs that won approval but also the ones that were shelved. Understanding this artistic context can help collectors appreciate the coins they hold — and can also help them evaluate unusual pieces that don’t fit neatly into established categories.
The Optical Illusion: A Lesson in Coin Examination
One of the most instructive moments in the forum discussion came when the original poster realized the symbols on the coin were not, in fact, raised — they were indented. The collector had been completely fooled by an optical illusion caused by the lighting angle in the photographs.
This is an incredibly common problem, and every collector needs to be aware of it. As forum member MasonG pointed out with surgical precision:
“Lighting is coming from above on the date. If the ‘&’ is raised, lighting is coming from the bottom. How does that work?”
Brilliant observation. It highlights a fundamental principle of coin photography and examination: the direction of light determines how relief appears in an image. If the light is coming from above, a raised feature will be illuminated on its upper surface and shadowed on its lower surface. If a feature appears to be lit from the opposite direction of the surrounding design elements, it’s almost certainly not raised — it’s either indented or the result of some other post-mint alteration.
Best Practices for Examining Unusual Coins
Based on my experience examining thousands of coins, here’s what I recommend for collectors who encounter unusual pieces:
- Use multiple light sources — Examine the coin under light coming from different angles. A genuine mint feature will behave consistently with the rest of the coin’s design under all lighting conditions.
- Use magnification — A quality loupe (10x minimum) or a digital microscope can reveal details completely invisible to the naked eye.
- Check the opposite side — If you see a mark on one side, look for corresponding disturbance on the other. A punch mark on the obverse will often leave clear evidence on the reverse.
- Compare with known examples — Use resources like the CONECA Master Files, VAMworld.com (for Morgan and Peace dollars), and error-ref.com to compare your coin against documented errors and varieties.
- Consult multiple experts — Don’t rely on a single opinion. The forum discussion we’re examining is a perfect example of how collective expertise arrives at a more accurate conclusion than any individual assessment.
- Be honest with yourself — As the original poster demonstrated, it’s easy to see what you want to see. Approach every unusual coin with healthy skepticism.
The Verdict: Post-Mint Alteration Confirmed
After extensive back-and-forth, the forum community reached a consensus: the symbols on the 1963-D cent were the result of post-mint alteration, most likely created using a counter-punch technique. The original poster graciously accepted this conclusion:
“Well, after re-checking the coin under the microscope, I am eating crow. You were all correct and my assertion that the symbols were raised was incorrect. I was definitely fooled by an optical illusion.”
That’s a remarkably mature and intellectually honest response — the kind every collector should aspire to. The willingness to revise your conclusions in the face of evidence is the hallmark of a serious numismatist.
What This Means for Collectors: Actionable Takeaways
The forum discussion offers several important lessons for collectors at every level:
For Buyers
- Always examine unusual coins under multiple lighting conditions before committing to a purchase
- Be deeply wary of coins marketed as “one of a kind” or “unique” — genuine rarities do exist, but the vast majority of unusual-looking coins are post-mint alterations
- Buy the coin, not the story — a compelling narrative doesn’t make a coin valuable. Focus on the physical evidence and the numismatic value the market actually assigns it
- Get a second opinion — if a coin seems too good to be true, consult a certified error specialist or submit it to a major grading service like PCGS or NGC
For Sellers
- Be transparent about provenance and condition for any unusual coin you’re offering
- Don’t make claims you can’t support — if you’re unsure whether a mark is a genuine mint error or PMD, say so
- Provide high-quality photographs taken under multiple lighting conditions to showcase the coin’s true eye appeal
- Price fairly — a post-mint alteration with an interesting story may have some collectibility, but it doesn’t command a genuine mint error premium
For the Hobby as a Whole
- Share knowledge freely — this forum discussion is a textbook example of how collective expertise benefits everyone
- Encourage newcomers — the original poster was a relatively new collector, and the community’s patient, respectful responses helped them learn
- Maintain high standards — the willingness to correct errors and revise conclusions is what makes numismatics a serious pursuit rather than mere speculation
Conclusion: The Enduring Value of Numismatic Knowledge
The story of the 1963-D cent with mysterious symbols is, in many ways, a microcosm of the numismatic hobby itself. It begins with curiosity, proceeds through investigation, and arrives at understanding — not always the understanding we expected, but one that deepens our appreciation for the art and science of coinage.
The Chief Engravers who designed the coins we collect — from Longacre to Gasparro and beyond — worked within a complex web of artistic tradition, political pressure, and technical constraint. Their rejected designs, their artistic influences, and the mint politics they navigated all left their mark on the coins we hold in our hands today. Understanding this context doesn’t just make us better collectors; it makes us better stewards of a cultural heritage that spans centuries.
The 1963-D cent in question may not be a “one of one” mint error, but it is something arguably more valuable: a teaching tool. It reminds us that the minting process is both an art and a science, that optical illusions can deceive even experienced eyes, and that the collective knowledge of the numismatic community is our most powerful instrument for separating genuine rarities from clever alterations.
As I always tell my students: the coin doesn’t care what you want it to be. It is what it is. Our job is to look closely, think critically, and learn from every single piece we encounter. That’s the true art of numismatics.
