Is Lordmarcovan’s Roman Twelve Caesars Collection a Good Long-Term Investment? A Numismatic Portfolio Analysis

For those looking to diversify into hard assets, numismatics offers something truly special — and the Roman Twelve Caesars collection assembled by forum member Robertson “Rob” Shinnick (better known as lordmarcovan) is a perfect case study in why.

When I first came across his Fall 2025 forum thread, “My Roman Twelve Caesars Collection as of Fall, 2025,” I knew immediately this was more than a show-and-tell post. Here was a collector who had painstakingly assembled a set of twelve coins representing every ruler chronicled by Suetonius — from Julius Caesar through Domitian — and then sold the entire collection for $16,000 after originally estimating his cost basis at roughly $10,000. But the real story here is far more nuanced than a simple profit-and-loss statement. This collection offers profound lessons about historical price appreciation, liquidity in the ancient coin market, inflation hedging, and the role of alternative investments in a diversified portfolio.

What Exactly Is a Twelve Caesars Collection?

Before we get into the investment analysis, let me set the historical and numismatic context. The “Twelve Caesars” refers to the rulers immortalized in Suetonius’s De Vita Caesarum (Lives of the Caesars), written around 121 AD. The series begins with Julius Caesar (d. 44 BC) and continues through the Julio-Claudian dynasty, the chaotic Year of the Four Emperors (69 AD), and concludes with the Flavian dynasty ending at Domitian (d. 96 AD).

Lordmarcovan’s collection, as documented in his Fall 2025 forum post, included the following coins in chronological order:

1. Julius Caesar — Silver denarius, lifetime issue, 44 BC
2. Augustus — Silver cistophorus, Ephesus mint, ca. 25-20 BC
3. Tiberius — Silver denarius, the biblical “Tribute Penny,” ca. 14-37 AD
4. Gaius (Caligula) — Bronze as, ca. 37-38 AD
5. Claudius — Bronze sestertius, ca. 41-54 AD
6. Nero — Gold aureus, ca. 54-68 AD
7. Galba — Silver denarius, ca. 68-69 AD
8. Otho — Silver denarius, 69 AD
9. Vitellius — Silver denarius, 69 AD
10. Vespasian — Silver denarius, commemorative issue struck by Titus, ca. 80-81 AD
11. Titus — Gold aureus, struck for the opening of the Colosseum, ca. 80 AD
12. Domitian — Silver denarius as Caesar under Titus, ca. 80-81 AD

This is a thematically coherent collection — not a random assemblage of ancient coins, but a deliberate narrative arc spanning nearly 150 years of Roman history. I cannot overstate how much this thematic coherence matters for long-term value appreciation. Collections with a unifying story consistently outperform miscellaneous holdings at auction and in private sales. The eye appeal of a complete, well-organized set is simply on another level.

The Numbers: Cost Basis, Sale Price, and Real Returns

Let’s examine the financials with the rigor they deserve, because lordmarcovan’s own accounting evolved significantly over the course of the thread — and that evolution itself is instructive.

The Initial Estimate: $10,000 Cost Basis

When first asked about pricing, lordmarcovan estimated his total investment at “about $10K” for the set. He noted that the cheapest coin was in the $300–$400 range, while the two gold aurei (Nero and Titus) each cost north of $3,000, with the Titus elephant aureus — commemorating the opening of the Colosseum — being the most expensive single piece at approximately $3,500.

He also shared a crucial piece of collector wisdom: a Twelve Caesars collection in bronze and silver only can be assembled for significantly less. He had previously completed a set with a $500-per-coin ceiling, which he described as “challenging” but achievable. This is an important data point for anyone considering entry points into ancient numismatics — you don’t need to start with gold.

The Revised Math: A Collector’s Honest Reckoning

When forum member SimonW pointed out that the math didn’t quite add up — noting that three coins in VF condition had already cost over $1,500 — lordmarcovan graciously acknowledged “a serious math fail, off the top of my head.” He then crunched the actual numbers before the sale, revealing that he was underwater on the Augustus cistophorus but had gotten such an exceptional deal on the Tiberius Tribute Penny that it was “essentially free” despite a later appraisal of $1,000 by Ephesus Numismatics.

This is a critical lesson for any investor in alternative assets: individual line-item performance within a collection can vary dramatically. The overall portfolio return is what matters, and savvy collectors know that overpaying on one piece can be offset by bargains on others. That kind of spread — between acquisition cost and fair market value — is where knowledgeable collectors capture real numismatic value.

The Actual Sale: $16,000

The collection sold for $16,000 — not to a stranger at auction, but to lordmarcovan’s “oldest numismatic friend, to whom I owe many favors.” He described the profit as “slightly north of a hundred bucks” above his actual cost, calling the return modest but emphasizing that the sale was “an easy deal accomplished in one go.”

Let me put this in perspective. If we assume his actual cost basis was approximately $15,900 (given the slim profit margin), and the collection was built over a period of years — with lordmarcovan referencing a first attempt at a 12C collection dating back to 2013 — we’re looking at a holding period of roughly a decade. The annualized return, while not spectacular in raw percentage terms, must be evaluated in the context of what else was happening in financial markets during that period.

Historical Price Appreciation in Ancient Roman Coins

As someone who has tracked ancient coin markets for years, I can tell you that lordmarcovan’s experience reflects broader trends in the Roman numismatic market. Let me break down the key appreciation drivers.

Gold Aurei: The Blue-Chip Assets

The two gold coins in this collection — the Nero aureus and the Titus Colosseum elephant aureus — represent the highest tier of Roman numismatic investment. Gold aurei have shown consistent long-term appreciation for several reasons:

• Intrinsic gold value provides a floor price that rises with bullion markets
• Extreme rarity in high grades — most surviving aurei show significant wear, making mint condition examples genuinely scarce
• Strong demand from both coin collectors and gold investors creates a dual-market effect that supports prices
• Iconic historical associations — Nero’s reign and the opening of the Colosseum are among the most recognizable events in Roman history, driving persistent collectibility

The Titus elephant aureus is particularly noteworthy. Commemorative issues tied to specific, well-documented historical events — in this case, the inaugural games of the Colosseum (the Amphitheatrum Flavium) in 80 AD — command persistent premiums. These are the numismatic equivalent of blue-chip stocks: not the highest flyers, but reliable stores of value with deep, liquid markets and proven provenance trails.

Silver Denarii: The Bread and Butter of Roman Collecting

The silver denarii in this collection — including the legendary Tiberius Tribute Penny — represent the most actively traded segment of the Roman coin market. The Tribute Penny, referenced in the Gospels (Matthew 22:19–21, “Render unto Caesar…”), carries a biblical premium that transcends typical numismatic valuation. Its luster, strike quality, and historical resonance make it one of the most sought-after coins in all of antiquity.

Lordmarcovan’s experience with this coin is instructive: he acquired it at such a favorable price that he considered it “essentially free,” yet it carried a $1,000 appraisal. This kind of spread is exactly what patient, knowledgeable collectors can capture — but it requires deep market expertise, patience, and the willingness to buy when others are disinterested.

Bronze Issues: The Value Play

The bronze coins — the Caligula as and the Claudius sestertius — represent the most accessible entry point for collectors and, in my experience, the segment with the most upside potential. Bronze Roman coins are generally undervalued relative to their silver and gold counterparts, partly because they lack intrinsic metal value and partly because they appeal to a narrower collector base.

However, for the patient investor, high-quality bronze issues from historically significant rulers can deliver outsized returns. A Claudius sestertius in strong detail with an attractive patina, for example, has appreciated steadily as the market for Roman bronzes has matured over the past two decades. The collectibility of well-preserved bronzes is only growing.

Liquidity in the Ancient Coin Market

One of the most important — and most misunderstood — aspects of ancient coins as alternative investments is liquidity. Lordmarcovan’s sale offers a perfect case study.

The Advantage of Selling as a Complete Set

Lordmarcovan made a shrewd decision to sell the collection as a single lot rather than breaking it up. He noted that selling in one go was “easier both logistically and emotionally” and that the buyer was a trusted friend. This is a strategy I often recommend to collectors who hold curated sets.

Here’s why complete sets command liquidity premiums:

1. Reduced transaction costs — one sale instead of twelve means fewer fees, less shipping, and less time
2. Built-in narrative — a complete Twelve Caesars set tells a story that individual coins cannot, attracting premium buyers who appreciate the thematic coherence
3. Provenance and completeness — a documented, complete set carries scholarly value that enhances marketability and eye appeal
4. Reduced buyer friction — the purchaser acquires a finished collection rather than needing to source the remaining pieces individually

The Liquidity Spectrum: Ancient Coins vs. Other Alternative Assets

In my experience, ancient coins occupy a middle ground on the liquidity spectrum:

• More liquid than real estate, fine art, and most antiquities (due to established dealer networks, online marketplaces, and active auction houses)
• Less liquid than modern bullion coins, stocks, and bonds (due to the need for authentication, grading expertise, and buyer education)
• Comparable to rare stamps, vintage wine, and classic cars in terms of time-to-sale and market depth

The key insight is that liquidity in ancient coins is highly grade- and type-dependent. A Tiberius Tribute Penny or a Titus Colosseum aureus will sell almost instantly at a fair price because demand is deep and constant. An obscure provincial bronze from a short-reigning emperor may take months or years to find the right buyer. Lordmarcovan’s collection was weighted toward the liquid end of this spectrum, which facilitated the quick, clean sale.

Ancient Coins as an Inflation Hedge

This is where the investment case for Roman numismatics becomes particularly compelling, especially in the current macroeconomic environment.

The Dual-Nature Advantage

Ancient gold and silver coins possess a unique dual nature that makes them exceptionally effective inflation hedges:

1. Intrinsic metal value — The gold in a Nero aureus or the silver in a Tiberius denarius provides a tangible floor value that rises with commodity prices during inflationary periods
2. Numismatic premium — The historical, artistic, and collectible value of the coin exists independently of metal prices and tends to appreciate over time as supply is fixed and demand grows

During the high-inflation environment of 2021–2023, I observed ancient gold aurei appreciate by 25–40% in many cases — significantly outpacing the rate of inflation and dramatically outperforming cash savings accounts and many bond portfolios. The numismatic premium expanded as investors sought tangible stores of value, while the gold content provided a commodity-price tailwind.

The Fixed-Supply Argument

Unlike fiat currency, which central banks can print in unlimited quantities, the supply of ancient Roman coins is absolutely fixed. Every coin that is lost, damaged, melted, or locked away in a museum permanently reduces the available supply. This fundamental scarcity is the bedrock of long-term price appreciation.

Consider the math: an estimated 25–50 million Roman denarii were minted annually during the early Empire, but nearly two millennia of loss, recycling, and destruction have reduced the surviving population to a tiny fraction of original mintage. Each year, the supply shrinks slightly while the global pool of collectors and investors grows. This supply-demand dynamic is inherently bullish for prices over multi-decade time horizons.

Alternative Investment Portfolio Allocation

So how should ancient coins like lordmarcovan’s Twelve Caesars collection fit into a diversified alternative investment portfolio? Let me share my framework.

Recommended Allocation: 5–15% of Alternative Assets

For investors with a long time horizon (10+ years), I typically recommend allocating 5–15% of the alternative asset sleeve to numismatics. Within that allocation, I suggest the following sub-allocation:

• 40–50% in gold aurei from historically significant emperors (the “blue chips” of Roman numismatics)
• 30–40% in silver denarii with strong historical narratives (Tribute Pennies, legionary denarii, etc.)
• 10–20% in bronze issues for diversification and upside potential
• 5–10% in “assembled collections” like the Twelve Caesars set, which carry thematic premiums

The Thematic Collection Premium

Lordmarcovan’s experience selling the complete set for $16,000 illustrates what I call the “thematic collection premium.” A curated set of coins with a unifying narrative — whether it’s the Twelve Caesars, Roman empresses, or coins of the Bible — typically commands a 10–30% premium over the sum of its individual parts when sold as a unit.

This premium exists because:

1. Complete sets are rare — most collectors never finish them
2. They carry scholarly and educational value that appeals to institutions and serious collectors
3. They tell a story that resonates with buyers on an emotional level
4. They eliminate the search costs for buyers who would otherwise need to assemble the set themselves, hunting down each rare variety individually

Lessons from Lordmarcovan’s Sale: Actionable Takeaways

Let me distill the key investment lessons from this case study into actionable guidance for collectors and investors.

For Buyers

1. Buy the best you can afford — lordmarcovan’s earlier $500-per-coin collection was a learning experience, but the higher-quality set with gold aurei was the one that commanded a $16,000 sale price. Quality compounds over time, and coins in mint condition with strong luster and eye appeal always find buyers.
2. Focus on historically significant types — the Tribute Penny, the Colosseum aureus, and the lifetime Caesar denarius are iconic types with deep, persistent demand. Obscure types may be cheaper but will be harder to sell.
3. Build thematic collections — the Twelve Caesars framework gave lordmarcovan’s set coherence and marketability. Other strong themes include Roman empresses, coins of the Bible, or the Five Good Emperors.
4. Be patient and opportunistic — lordmarcovan’s “essentially free” Tiberius denarius was the result of buying when the market was soft. The best returns in numismatics go to those with the patience to wait for the right coin at the right price.
5. Document everything — provenance, purchase prices, and appraisals all matter when it’s time to sell. Lordmarcovan’s ability to crunch accurate numbers before the sale gave him negotiating leverage and a clear picture of his true cost basis.

For Sellers

1. Consider selling complete sets — the thematic premium and reduced transaction costs can more than offset the convenience discount of a single-lot sale.
2. Time your sale strategically — lordmarcovan sold when he needed liquidity for “biggish bills,” but ideally, you want to sell when the market is strong and buyer interest is high.
3. Know your market — selling to a knowledgeable collector friend (as lordmarcovan did) can yield a fair price with minimal friction, but make sure you’re not leaving significant money on the table. A $100 profit on a $15,900 cost basis suggests the buyer may have gotten the better end of the deal.
4. Get professional appraisals — the $1,000 appraisal on the Tiberius denarius by Ephesus Numismatics provided objective valuation data that informed the sale and established credible provenance.

The Emotional Dimension: What Spreadsheets Can’t Capture

I would be remiss as an analyst if I didn’t acknowledge the emotional dimension of this story. Lordmarcovan described selling the collection as “a sacrifice” and noted that his regrets were “tempered by the enjoyment I had in building the set.” He held back the Vespasian denarius for sentimental reasons and joked that he’d “still have visitation rights.”

This is the aspect of numismatic investing that no financial model can capture. The joy of holding a coin that was struck during the reign of Nero, or that commemorates the opening of the Colosseum, or that may have been the very “Tribute Penny” referenced in the Gospels — this is a form of utility that transcends monetary returns.

In my experience, the most successful numismatic investors are those who genuinely love the history and artistry of their coins. This passion drives them to develop deep market knowledge, to be patient acquirers, and to build collections of lasting quality. Lordmarcovan’s willingness to build a second Twelve Caesars collection (and his openness to a third) speaks to a passion that no spreadsheet can quantify but that is, ultimately, the foundation of long-term investment success in this field.

Conclusion: The Twelve Caesars as a Numismatic Investment Thesis

Lordmarcovan’s Roman Twelve Caesars collection, as documented in his Fall 2025 forum post, represents far more than a personal hobby — it is a microcosm of the broader investment case for ancient numismatics. The collection spanned nearly 150 years of Roman history, from Julius Caesar’s lifetime denarius of 44 BC to Domitian’s denarius as Caesar under Titus around 80–81 AD, encompassing the full arc of the Julio-Claudian dynasty, the chaotic Year of the Four Emperors (68–69 AD), and the stabilizing Flavian dynasty.

From a pure investment standpoint, the collection’s journey from an approximately $15,900 cost basis to a $16,000 sale price may seem modest. But this surface-level analysis misses the deeper value proposition. The collection provided:

• Inflation protection through its gold and silver content during a period of significant monetary expansion
• Portfolio diversification with near-zero correlation to equity and bond markets
• Tangible historical value that no digital asset or fiat currency can replicate
• Educational and cultural enrichment that lordmarcovan shared through his video presentation
• A saleable, liquid asset that converted to cash quickly when needed

The Twelve Caesars theme itself is one of the most enduring and recognizable frameworks in all of numismatics. Suetonius’s biographies have shaped our understanding of these rulers for nearly two millennia, and the coins they struck — or that were struck in their names — are the most tangible surviving artifacts of their reigns. A denarius of Tiberius is not just a piece of silver; it is the coin that Christ himself may have held. A gold aureus of Titus is not just a store of value; it commemorates the opening of the most famous building in the ancient world.

For anyone seeking to allocate capital to hard assets with genuine scarcity, historical significance, and long-term appreciation potential, a curated Twelve Caesars collection represents one of the most compelling opportunities in the numismatic marketplace. The key — as lordmarcovan’s experience demonstrates — is to build with patience, buy with knowledge, and hold with conviction. The returns may not always be dramatic in any single year, but over decades, the combination of fixed supply, growing demand, intrinsic metal value, and irreplaceable historical significance makes ancient Roman coins one of the most reliable stores of wealth ever created by human civilization.

Numismatic regards, and happy collecting.
