Photographing the 1907 Saint-Gaudens $20 Omega Counterfeit: Axial Light, Macro Detail, and Cartwheel Luster
September 30, 2026The venue you choose can change the profit on the very same coin. When collectors ask me where to sell coins for more—eBay or coin shows—the honest answer is that the coin and the seller matter. An eBay buyer may discover your offering at midnight in Ohio. At a show, a dealer can examine it under a lamp, recognize an important variety, and make an immediate offer in New Jersey. Both are serious numismatic markets, but they operate under very different economics.
As an online coin dealer, I have learned that the number printed on a listing or written on an invoice tells only part of the story. That figure is the gross sale price. What matters is the money I actually keep after fees, shipping, insurance, grading, advertising, table expenses, returns, and taxes. A coin can bring thousands of dollars on eBay and still earn more through a dealer’s buy offer. The reverse can happen just as easily.
A recent numismatic discussion about a holdered 1907 Saint-Gaudens $20 High Relief Omega counterfeit offers a revealing example. The piece was openly described and graded as a counterfeit, yet the discussion reported a sale of about $9,843.75. Its numismatic value came from specialist interest, transparent attribution, and its collectibility within the history of imitation—not from passing it off as genuine. That distinction is essential at both an online marketplace and a coin show.
eBay Fees: What the Buyer Sees Is Not What You Keep
Build the real net-proceeds formula
eBay offers global reach, but that reach does not cancel its fees. The final-value fee depends on the category, selling format, sale price, location, and seller account status. Promoted listings, store subscriptions, shipping charges, and optional services can add more. Because rates change, I never price from memory. I check eBay’s current fee calculator immediately before publishing a listing.
For any collectible coin, I use this working calculation:
Net proceeds = sale price + shipping charged to buyer − eBay fees − outbound shipping − insurance and packaging − promoted listings − grading and return costs − seller-paid sales tax − labor.
Marketplace-collected sales tax generally passes through to the taxing authority and should not be counted as income. Payment-processing charges, photography, scales, flips, capsules, outer mailers, and the seller’s time still count. For an expensive coin, the cheapest shipping option can become a false economy if it provides inadequate tracking, insurance, or evidence of careful packing.
An illustrative eBay example
Assume a coin sells for $1,000 and the applicable eBay final-value fee is hypothetically 13.25 percent. The fee would be $132.50. If shipping costs the seller $25, packing materials cost $12, and promoted listings cost $15, the seller would retain approximately $815.50 before labor and other overhead.
Now consider a dealer willing to purchase the same coin immediately for $775. That is not an insulting offer. After eBay expenses, the dealer’s bid may produce more net money while also eliminating the listing work, buyer conversations, shipping exposure, and return risk. A gross eBay price should never be compared with a dealer’s gross bid until the arithmetic is done.
- Price for your net target. Decide the amount you need to keep, then work backward through every charge.
- Remember the delivered price. Buyers compare the total cost with competing listings, not just the winning bid.
- Insure valuable coins. Protection may cost less than the risk of an underinsured shipment.
- Account for grading and returns. A promising auction-style price can disappear if the coin returns with a lower designation.
- Count your time. Ten inexpensive sales may earn less than one qualified buyer who pays promptly.
None of this makes eBay a poor venue. It makes eBay a retail sales channel with the same need for disciplined pricing as a show table or shop window.
Coin-Show Economics: Table Fees and Dealer Spreads
The true cost of a show weekend
A coin show may charge no commission on an individual sale, but a “free” table is not really free. Dealer fees, badges, power, chairs, cases, security, transportation, lodging, assistants, insurance, and post-show shipping all add up. Some shows also impose setup and dismissal deadlines. I divide the full show cost by the number of transactions I realistically expect—not by my most optimistic sales target.
For example, a $700 table fee costs $35 per sale if the dealer makes 20 substantial transactions. It becomes painful if only three close. A $4,000 show sale, after $300 in allocated show expenses, leaves $3,700 before travel and labor. By comparison, a $4,000 eBay sale subject to a hypothetical 13.25 percent final-value fee, $50 shipping, $50 in materials, and $100 in promotion would retain approximately $3,270 before other costs. Under those assumptions, the show offers $230 more—but only when the inventory is actively sold.
Shows also compress travel and selling time. A single table can place an inventory before hundreds or thousands of qualified collectors, often more efficiently than weeks of online advertising. The disadvantage is concentration. A slow table, bad weather, competing shows, or weak local economic conditions can leave inventory unsold.
Selling direct to show buyers
A public table allows the seller to keep the retail price, but display security, buyer questions, payment methods, and private negotiations still require attention. High-value purchases may need a wire, bank transfer, or insured delivery after the show. I never treat a handshake as a completed sale until the funds have cleared and every agreed term is documented.
A dealer offering immediate cash or a firm bank payment can be especially useful when:
- the seller needs liquidity rather than a record-high nominal result;
- the coin falls outside the seller’s usual specialization;
- another investment or project offers a better return;
- insurance or safe transport is difficult to arrange; or
- the seller wants to avoid an uncertain, prolonged marketplace listing.
Dealer Buy Prices: Wholesale Is Not Retail
What determines my offer
When I buy a coin from another dealer, I am not simply paying the seller’s desired retail figure. I must account for inventory risk, overhead, future marketing time, returns, grading expenses, and the possibility that the coin may sit unsold. A retail price is a target. A dealer’s bid is a transaction I can complete today.
When I evaluate a coin on a show table, I consider:
- Authenticity and provenance: Does the documentation support the attribution? Are there signs of alteration, repair, restriking, or a later holder that affects marketability?
- Rarity and collector demand: Is this a rare variety with an established following, or a common date whose value depends mainly on a small number of high-grade examples?
- Condition and eye appeal: Strike, centering, luster, color, surfaces, and damage can create a wider price difference than many sellers expect. “Mint condition” is not a grade, and patina is subjective. Original toning may add appeal to one collector and detract from another; harsh cleaning usually harms both eye appeal and numismatic value.
- Certification status: A recognized holder can improve liquidity, but its fee and marketability must be included. It is not automatically worth the consumer price.
- Seller motivation: A quick wholesale offer may be useful for a common coin but inadequate for a scarce rarity supported by strong documentation.
- Current bids, not optimistic asking prices: Completed sales and firm dealer bids offer a better guide than the highest number in an old listing.
For a 1907 Saint-Gaudens High Relief, I examine the date style, dramatic relief, planchet, strike, and attribution before assigning numismatic value. The authorized Roman-numeral MCMVII High Relief pattern is a distinct rarity and should not be confused with the ordinary 1907 Arabic-numeral double eagle. A private Omega copy presents a different kind of attraction: it belongs to the history of imitation and collecting, not to the authorized Philadelphia Mint issue.
I recommend obtaining more than one opinion on any high-value coin. One offer is a data point, not a universal market price. If a dealer’s bid falls below your minimum, you are not obligated to accept it. The important question is whether that bid reflects present wholesale demand or merely the dealer’s personal inventory preferences.
Liquidity: A Global Marketplace Versus Concentrated Buyer Traffic
Where eBay has the advantage
eBay provides continuous global exposure. A buyer in another country can search an exact date, mint mark, variety, grade, or error while you sleep. A well-described listing can also attract searches for years, particularly when its terms are specific and the photographs clearly document the coin’s condition and identity.
The marketplace is especially effective for:
- circulated coins with recognizable dates and mint marks;
- under-$100 pieces that benefit from inexpensive shipping;
- coins whose photographs can answer basic condition questions;
- specialist searches for a specific die variety, mint mark, or grading designation; and
- sellers building a documented, multyear online selling record.
eBay’s price transparency is both an advantage and a constraint. Competing listings encourage informed buyers, but the lowest visible price can become a buyer’s benchmark. I distinguish my coins with clear photography, precise attribution, strong packaging, and an honest discussion of flaws—not vague claims such as “museum quality.”
Where coin shows have the advantage
A show concentrates specialist attention into a short period. Collectors can inspect surfaces, strike, luster, and edge characteristics in person, then take the purchase home without waiting for insured shipping. That immediacy is valuable for scarce coins and high-value material. Eye appeal also tells a different story in person than it does on a phone screen, and a serious buyer can ask informed questions face to face.
Shows are usually stronger for:
- expensive coins whose buyers want an in-person examination;
- coins with exceptional eye appeal that photographs cannot fully convey;
- material with documented provenance that established local collectors recognize;
- dealer stock that a customer wants to hold and compare; and
- recognized numismatic specialties where attendance is predictable.
The most liquid strategy is often sequential. A dealer may test demand through accurate eBay listings, attend a major show, and then offer a scarce coin in a specialist auction. I choose the venue according to the coin rather than insisting that one channel is always superior.
