Auction House Secrets: How to Maximize Profits Selling Elongated and Flattened Cents at Major Auction

There is a massive difference between selling on eBay and consigning to a major auction house. Let’s look at how to position this item for the highest hammer price.

As an auction house director who has spent over two decades handling numismatic rarities and exonumia, I can tell you that few niches in the collecting world are as misunderstood — or as undervalued — as the market for elongated cents and flattened (railroad) cents. These fascinating pieces of Americana sit at the intersection of mechanical ingenuity, folk art, and numismatic history. Yet when they arrive on my desk for evaluation, I’m consistently surprised by how little many consignors understand about the process of bringing them to auction. Today, I’m pulling back the curtain on exactly how a major auction house approaches these items — and how you, as a collector or seller, can position your elongated and flattened cents to achieve the strongest possible results.

Understanding What You Actually Have: Elongated Cents vs. Flattened Cents

Before we discuss auction strategy, let me clarify the distinction between these two closely related but fundamentally different collectible categories, because the market treats them quite differently.

Elongated Cents: The Rolling Mill Process

An elongated cent is created when a coin — typically an Indian Head cent or Lincoln cent — is fed through a pair of engraved rollers that stretch and flatten the design while impressing a new image, message, or advertisement onto the obverse and reverse. These were produced as souvenirs, promotional items, and business cards at world’s fairs, expositions, tourist attractions, and commercial establishments from the late 1800s through the present day.

The elongation process fundamentally alters the coin’s dimensions. A standard Lincoln cent measures approximately 19.05mm in diameter; an elongated cent can stretch to 30mm, 40mm, or even longer depending on the machine and the operator. The original design elements — Lincoln’s profile, the date, the mint mark — are still visible but stretched and distorted, which is part of the charm.

Some collectors specialize in elongations produced on obsolete host coins — Buffalo nickels, Indian Head cents, and other denominations that are no longer in circulation. These carry a particular appeal because the host coin itself has collectible value independent of the elongation. A Type 6 elongation rolled on a Buffalo nickel, for instance, appeals to two distinct collector bases simultaneously. That dual collectibility is something I always flag when evaluating a consignment, because it directly broadens the bidding pool.

Flattened (Railroad) Cent: Accidental or Intentional?

Flattened cents, sometimes called “railroad cents” or “machine-flattened cents,” are coins that have been compressed and deformed by mechanical force — most famously by being placed on railroad tracks and run over by a passing train. Unlike elongated cents, which are produced by a controlled rolling mill process with intentional design elements, flattened cents are typically the result of a single compressive force that smears the coin into an oval or irregular shape.

The collectibility of flattened cents is more niche, but dedicated collectors do exist. Organizations like CONECA (Combined Organizations of Numismatic Error Collectors of America) recognize flattened and deformed coins as part of the broader error and exonumia category. The key factors that determine numismatic value include:

• The clarity of the remaining design — Can you still read the date? Is Lincoln’s profile or the wheat ears visible? Sharp detail transfer is everything.
• The host coin’s date and mint mark — A flattened 1909-S VDB Lincoln cent is inherently more desirable than a flattened 1974 cent, regardless of the deformation. The rarity of the host coin sets the floor.
• The nature of the deformation — Was it a clean, single pass over a rail, or a mangled, multi-directional crush? Clean, uniform deformation commands a premium.
• Provenance and story — Was it flattened at a specific location? Does it have a documented history? A compelling backstory adds genuine eye appeal.

The eBay Trap: Why Most Sellers Leave Money on the Table

I understand the temptation. eBay is fast, familiar, and seemingly straightforward. You snap a photo with your phone, write a quick description, set a starting price, and wait. For common elongated cents — the kind you’d find at a tourist trap in Branson, Missouri, or a boardwalk in Ocean City, New Jersey — eBay is perfectly adequate. The market is liquid, buyers are plentiful, and the transaction costs are relatively low.

But here’s what I see every day in my role: sellers of truly significant elongated and flattened cents routinely undervalue their items on eBay because they don’t understand the specialized market that exists for these pieces. A rare 1893 World’s Columbian Exposition elongated cent in choice condition might sell for $47 on eBay because the seller titled it “old squished penny” and the right collectors never saw it. That same piece, properly catalogued and presented in a major auction, could realize $300 to $800 or more.

The difference comes down to five critical factors that a major auction house brings to the table: buyer’s premiums, seller’s fees, auction timing, professional photography, and catalogue descriptions. Let me walk through each one.

Buyer’s Premiums: The Hidden Engine of Auction Pricing

The buyer’s premium is the percentage fee that the auction house charges the buyer on top of the hammer price. At most major numismatic auction houses, this ranges from 18% to 26%, depending on the platform (in-house bidding vs. online bidding).

Many sellers view the buyer’s premium with suspicion — “Why should the buyer pay extra?” — but as an auction house director, I can tell you that the buyer’s premium is actually one of the most powerful tools for maximizing your net proceeds. Here’s why:

1. It shifts the cost burden to the buyer. When you sell on eBay, you pay the seller fees (typically 13% for coins), and the buyer pays nothing beyond the winning bid. In an auction house setting, the buyer’s premium means the seller’s commission can be lower — sometimes zero for high-value consignments.
2. It creates a psychological separation between the “price” and the “cost.” Bidders focus on the hammer price. A bidder who is willing to pay $500 for a rare elongated cent will bid $500 whether there’s a buyer’s premium or not — they’re bidding against other bidders, not against the fee structure.
3. It funds the infrastructure that drives higher prices. The buyer’s premium pays for the professional photography, expert cataloguing, targeted marketing, and the auction platform itself — all of which contribute to stronger bidding and higher hammer prices.

For elongated and flattened cents specifically, the buyer’s premium model works exceptionally well because these items attract passionate, knowledgeable collectors who understand the auction process and factor the premium into their maximum bid from the start.

Seller’s Fees: Understanding the Consignment Structure

Let me be transparent about how seller’s commissions work, because this is where I see the most confusion among potential consignors.

Most major numismatic auction houses operate on a sliding commission scale based on the estimated value of the consignment:

• High-value consignments (items estimated at $5,000+): Seller’s commission of 0% to 10%, sometimes with a minimum flat fee.
• Mid-range consignments ($500 to $5,000): Seller’s commission of 10% to 15%.
• Entry-level consignments (under $500): Seller’s commission of 15% to 20%, or a flat consignment minimum.

Some auction houses also charge photography fees, insurance fees, and cataloguing fees for lower-value lots. This is where you need to read the consignment agreement carefully. At our house, we waive all ancillary fees for consignments with a total estimated value above $1,000, because we believe the buyer’s premium model should cover our costs on those lots.

Actionable takeaway: If you have a collection of elongated or flattened cents, consign them as a single lot or in grouped lots rather than piecemeal. A collection of 50 elongated cents from the early 1900s, presented as a curated lot with a combined estimate of $1,500, will earn you a significantly better commission rate than 50 individual lots estimated at $30 each. More importantly, collectors love buying collections — it’s more exciting, it tells a story, and it often triggers competitive bidding.

Auction Timing: The Single Most Underestimated Factor

In my experience, when you sell matters almost as much as how you sell. The numismatic auction calendar is not random — it follows predictable patterns that smart consignors can exploit.

The Major Auction Cycles

The biggest numismatic auctions of the year are typically tied to major coin shows:

• January: FUN Show (Florida United Numismatists) — one of the largest auctions of the year, with massive collector attendance and aggressive bidding.
• March/April: Central States Numismatic Society convention — strong midwestern collector base, excellent for type coins and exonumia.
• August: ANA World’s Fair of Money — the premier event of the year, attracting the deepest pockets and the most competitive bidders.
• October/November: Fall auction season — year-end buying as collectors use remaining budget allocations.

For elongated and flattened cents, I recommend targeting the August ANA auction or a specialized exonumia sale if the auction house offers one. The ANA show draws members of The Elongated Collectors (TEC) — the organization referenced in the forum discussion at tecnews.org — and these are the exact collectors who will pay premium prices for rare and unusual pieces.

Seasonal Considerations

Beyond the show calendar, consider the broader economic environment. Numismatic collectibles tend to perform well during periods of economic uncertainty (as tangible assets become more attractive) and during periods of economic confidence (when collectors have disposable income). Avoid consigning during the summer doldrums of June and July, when many collectors are on vacation and online bidding activity drops noticeably.

Professional Photography: Worth a Thousand Words and Hundreds of Dollars

I cannot overstate this: photography is the single most important factor in determining whether your elongated or flattened cent sells for $25 or $250.

When I review consignments, I can immediately tell which sellers have tried to photograph their items themselves and which have relied on professional numismatic photographers. The difference is stark. Here’s what professional photography brings to the table:

What Professional Numismatic Photography Captures

• Surface detail: The quality of the elongation — whether the design is sharp and well-strained or mushy and poorly defined — is critical to value. Professional macro photography reveals these details.
• Host coin identification: For elongated cents, the date, mint mark, and series of the host coin must be clearly visible in the photographs. A 1909-S Lincoln cent elongation is worth multiples of a common-date elongation.
• Color and toning: Original red or red-brown copper color on the host coin adds significant value. Professional lighting captures toning accurately without the color distortion that phone cameras introduce.
• Edge condition: Elongated cents can have edge cracks, laminations, or other condition issues that are invisible in casual photos but obvious in professional shots.
• Scale: Professional photos include a scale reference, so bidders can appreciate the actual size of the piece.

The Cost-Benefit Analysis

Professional numismatic photography typically costs $5 to $15 per lot for standard items, and $15 to $30 per lot for high-value or complex pieces. If you have a collection of 20 elongated cents being sold as a single lot, you might pay $20 to $30 for a set of professional images. If those images increase the hammer price by even $100 — which is a conservative estimate based on my experience — the return on investment is extraordinary.

Actionable takeaway: If the auction house offers professional photography as part of the consignment package (and most major houses do), always accept it. If you’re selling independently, invest in a decent macro lens or hire a photographer who specializes in coins. The difference in final sale price will more than cover the cost.

Catalogue Descriptions: The Art of Telling the Story

This is where the auction house director in me gets genuinely excited, because the catalogue description is where we transform a piece of deformed copper into a compelling collectible with historical significance and emotional resonance.

What Makes a Great Catalogue Description

A great catalogue description for an elongated or flattened cent does three things simultaneously:

1. It identifies the object precisely. Host coin type, date, mint mark, elongation type (if known), and any identifying features of the design or inscription.
2. It provides historical context. Where was this elongation produced? For what occasion? By whom? A cent elongated at the 1901 Pan-American Exposition in Buffalo, New York, is not just a squished penny — it’s a tangible artifact of a specific moment in American history.
3. It establishes rarity and desirability. How many examples of this type are known? Is it listed in the Token Catalog (tokencatalog.com), which is the standard reference for elongated and experimental coinage? What is the population in major collections?

A Sample Description

Here’s how I would describe a significant elongated cent in our catalogue:

Lot 1247. 1909 Lincoln Cent, Elongated on Buffalo Nickel Host. A remarkable and visually striking Type 6 elongation produced on a 1916-D Buffalo nickel, featuring a detailed patriotic eagle design on the obverse and the inscription “REMEMBER THE MAINE” on the reverse. The host coin’s date and mint mark are partially visible beneath the elongation, confirming the Denver issue. Bright golden surfaces with excellent detail transfer from the rolling dies. Minor edge nick at 3 o’clock on the reverse, otherwise choice. Listed in the Token Catalog (TC-673757). Ex-Lord Marcovan collection. A superb example of the elongater’s art that appeals equally to Lincoln cent collectors, Buffalo nickel specialists, and exonumia enthusiasts. Estimate: $400-600.

Notice what that description accomplishes: it identifies the host coin (1916-D Buffalo nickel), specifies the elongation type (Type 6), references the standard catalogue (Token Catalog), provides provenance (Lord Marcovan collection), describes the condition honestly, and — crucially — identifies three distinct collector audiences who might compete for this lot. That last element is what drives bidding wars.

The Importance of Provenance

Speaking of provenance: if your elongated or flattened cents come from a named collection — especially one mentioned in the numismatic literature or known within the TEC community — make sure the auction house knows. Provenance from a recognized collector like Klif50 (who was identified in the forum thread as a known flattened cent specialist) or Lord Marcovan (whose elongations are catalogued in the Token Catalog) adds a layer of authenticity and desirability that can meaningfully increase the hammer price.

Building the Right Collector Audience

One of the most significant advantages of consigning to a major auction house is access to a curated database of collectors who have specifically registered interest in exonumia, elongated cents, and error coins. When we list a significant elongated cent, we don’t just put it in the general auction — we flag it for targeted email campaigns to collectors who have previously bid on similar items.

This is something that eBay simply cannot replicate. On eBay, your item is visible to anyone searching for it — but the right collectors may never think to search for “elongated cent” or “flattened penny.” At a major auction house, we bring the collectors to the item.

For sellers, this means that even a relatively modest collection of elongated cents can generate surprising results if it reaches the right audience. I’ve seen lots estimated at $200 hammer at $600 or more because two TEC members got into a bidding war over a particularly scarce 1893 Columbian Exposition piece.

Authentication and Grading Considerations

One question I’m frequently asked: Can elongated and flattened cents be graded by third-party services like PCGS or NGC?

The answer is nuanced. Major grading services do not typically encapsulate elongated or flattened cents in the same way they grade standard coins. However, they may offer verification services that confirm the item is a genuine elongation (not a modern fake) and identify the host coin. For high-value pieces, this verification can add significant confidence for bidders.

More commonly, the auction house’s own experts provide the authentication. When I examine an elongated cent, I’m looking for:

• Consistency of the elongation pattern with known genuine examples from the same machine or operator.
• Appropriate aging and patina — modern fakes often have artificial toning that doesn’t match the expected surface characteristics of a copper coin of that era.
• Correct host coin characteristics — the date, mint mark, and design details of the host coin should be consistent with genuine issues of that type.
• Edge characteristics — genuine elongations have specific edge features depending on the type of machine used.

If you’re a seller, having your pieces pre-verified — or at least well-documented with reference to the Token Catalog or TEC publications — will make the auction house’s job easier and your consignment more attractive to bidders.

Conclusion: The Hidden Value in Deformed Cents

Elongated and flattened cents occupy a unique and often overlooked niche in the numismatic marketplace. They are simultaneously coins, mechanical novelties, historical artifacts, and folk art. The community of collectors — organized through groups like The Elongated Collectors (TEC) and CONECA — is passionate, knowledgeable, and willing to pay strong prices for pieces that are properly presented and authenticated.

If you have a collection of these fascinating items sitting in a drawer or a shoebox, I encourage you to look at them with fresh eyes. That flattened 1909-S VDB cent might be worth far more than you think. That set of early 1900s elongated cents from various world’s fairs could be the star lot of a specialized exonumia sale.

The key takeaways for maximizing your results at auction are straightforward:

1. Consign to a major auction house rather than selling piecemeal on eBay, especially for better-quality or historically significant pieces.
2. Understand the fee structure — buyer’s premiums, seller’s commissions, and ancillary costs — so you can negotiate the best possible consignment terms.
3. Time your consignment to coincide with major numismatic events like the ANA World’s Fair of Money, where the deepest collector pools are assembled.
4. Invest in professional photography that captures the detail, color, and scale of your pieces.
5. Provide the auction house with as much information as possible — provenance, host coin identification, historical context, and references to standard catalogues like the Token Catalog.

The difference between a $50 eBay sale and a $500 auction hammer price often comes down to presentation, timing, and access to the right audience. As an auction house director, my job is to bridge that gap — to take your elongated and flattened cents and present them in the best possible light to the collectors who will appreciate them most. The market is there. The collectors are there. All that’s needed is the right strategy to bring them together.
