Presidential $1 Coins vs. Ancient Roman Denarii: Mintage, MS70 Slabs, and Historical Value
October 2, 2026A coin can command an impressive headline price and still deliver a disappointing profit. The difference is often the venue. On eBay, I can reach collectors across the country and around the world. At a coin show, serious buyers and dealers gather under one roof, often producing an answer in minutes. As an online coin dealer, I have examined, photographed, offered, and sold coins through both channels. Each works, but each rewards a different approach.
Neither venue automatically produces the best result. A venue cannot create numismatic value, but it can determine how much of that value actually reaches the seller. Certification, rare-variety status, condition, eye appeal, presentation, reputation, and selling fees all affect the outcome. The real question is not simply, “Which brings the higher offer?” It is, “Which leaves the largest defensible net profit?”
PCGS’s new membership tiers, expanded submission access, eBay authentication program, and anticipated holder have added another consideration for sellers. These developments may make grading and authentication more accessible, but they do not guarantee a premium for a newly certified coin. Here is how I evaluate the marketplace when choosing between eBay and a coin show.
1. Why PCGS’s Changes Matter When You Are Ready to Sell
Recent PCGS announcements covered several developments: submission tiers for non-members, an improved online submission process, local drop-off events, expanded banknote services, a new holder with added security features, and an eBay program under which qualifying raw or slabbed U.S. and world coins valued at at least $500 would be sent directly to PCGS for authentication before delivery to the buyer.
For sellers, improved access is the immediate story. If PCGS no longer requires every submitter to maintain a paid collector membership, more collectors may be able to submit coins without first deciding whether membership makes financial sense. That is a meaningful benefit for an occasional submitter. It may also bring more certified coins onto the market, giving buyers greater choice and placing more emphasis on eye appeal, rarity, and realized auction results.
The eBay arrangement is easy to overinterpret, so sellers should distinguish among these arrangements:
- Raw coin offered on eBay: The coin is ungraded when listed, although it may qualify for routing through PCGS’s authentication program.
- PCGS-graded coin: The coin has already been authenticated and graded by PCGS and is being offered in its holder.
- PCGS-graded submission: The sale is made contingent on sending the coin to PCGS for grading after the sale, subject to the service’s current rules and fees.
- Third-party authentication: A grading service has evaluated the coin but has not assigned it a numerical grade.
These distinctions belong in the listing, stated accurately. A coin graded by PCGS does not make the seller a PCGS-authorized dealer, and a seller should never imply otherwise. Likewise, “PCGS authentication” should not be presented as “PCGS grading.” The distinction sets buyer expectations and can affect the possibility of a return if the coin is rejected.
The certification label can establish trust, but the coin remains the product. Rarity, strike, luster, surface quality, and historical importance determine its value—not the holder alone.
2. The Real eBay Fee: Why a 10 Percent Discount Can Kill Your Profit
eBay is exceptionally effective at finding buyers for certified coins. Its active collector base, search engine, completed-listing data, and international reach are difficult for a single coin show to match. The tradeoff is cost. A seller who watches only the final selling price is calculating gross revenue, not profit.
I calculate actual eBay proceeds with a simple formula:
Net proceeds = sale price + buyer-paid shipping − selling fees − payment fees − optional advertising − shipping and insurance − packaging − return reserve.
The exact eBay rate depends on the category, transaction date, seller location, buyer location, and services selected at checkout. Promotional credits and category
