What Is the Real Value of Rare French Patterns and Essais in Today’s Market? A Professional Appraiser’s Deep Dive

Determining the true worth of a rare French pattern or essai means looking far beyond any printed price guide. As a professional appraiser who has spent decades evaluating world coins, patterns, and essais, I can tell you that the market for French numismatic rarities is one of the most fascinating—and volatile—segments in all of collecting. A catalog listing often captures only a fraction of what serious collectors and investors will actually pay when a truly exceptional piece surfaces. In this analysis, I want to walk you through the current market dynamics shaping the value of French patterns and essais, using a recent high-profile auction as our case study.

The Auction Floor: Where Real Prices Are Made

The thread that inspired this piece centers on an MDC Monaco Auction conducted through Sixbid.com—one of the premier venues for world coin rarities. If you are not familiar with the landscape, MDC Monaco consistently offers what seasoned collectors describe as a “great (and pricey) selection.” They sit at the top tier alongside firms like Palombo and NGSA, both of which have built formidable reputations for handling exceptional world coinage. When these houses assemble a catalog, the serious money follows.

But here is what I always tell my clients: the auction floor is where book value goes to die. A coin’s “book price”—the figure you might find in a catalog or price guide—represents a theoretical baseline. It accounts for metal content, general rarity, and historical auction averages. What it does not account for is the emotional intensity of a live bidding war between two or three collectors who have been waiting years for a specific piece. That is where the “fat checkbook” comes in.

French Patterns and Essais: The Undervalued Frontier?

One collector in the thread made an observation that I find particularly astute: “I think I’m going to start collecting French patterns and essais. More coins. Less competition. And they are beautiful!” On the surface, this sounds like a brilliant strategy. Patterns and essais—trial strikes and design concepts never adopted for circulation—represent some of the most artistically compelling and historically significant pieces in all of numismatics. They are the “what ifs” of monetary history, and they often showcase engraving artistry that surpasses the final adopted designs.

The Appeal of French Patterns

France has one of the richest pattern coin traditions in the world. From the Napoleonic era through the Third Republic and beyond, the Paris Mint and private engravers produced an extraordinary variety of experimental designs. The collector in our thread specifically references building a “framework for typesets for Monarchs and/or various periods in French History”—and this is precisely the kind of systematic, historically grounded approach that tends to produce the most valuable and intellectually satisfying collections.

Consider the scope:

• Monarchical periods: Patterns from the reigns of Louis-Philippe, Napoleon III, and earlier monarchs each carry distinct design vocabularies and historical contexts.
• Republican eras: The Third Republic alone produced an enormous variety of essais as France debated its national identity through coinage design.
• Private engravers: Names like Pillet—referenced prominently in our thread—represent a specialized sub-category that dedicated collectors pursue with particular intensity.

The Piedfort Factor

One detail that deserves special attention is the mention of Piedfort Essai issues. A piedfort is a coin struck on a planchet of double (or sometimes more) normal thickness. In the world of patterns and essais, piedforts occupy a special niche because they were typically produced in extremely limited quantities—often as presentation pieces for mint officials or as examples of the engraver’s work. The double thickness gives these coins a substantial, almost medallic quality that sets them apart visually and tactilely from standard strikes. In my experience, piedfort essais command a significant premium over their standard-thickness counterparts, often 200% to 500% more depending on the specific issue and condition.

Case Study: The Pillet Silver Essai — A Masterclass in Rarity Premium

The centerpiece of our thread is a collector’s acquisition of what they describe as a very rare silver strike of a Pillet essai—a piece that deviates from the norm in several critical ways. Let me break down why this coin commanded the price it did, because each factor is a lesson in how the market values extreme rarity.

Metal Composition as a Value Driver

The collector notes that “These Pillet essais are normally struck in nickel.” This single fact is enormously significant. When a pattern or essai exists primarily in one metal—in this case, nickel—and a specimen surfaces in a different metal, such as silver or gold, the rarity multiplier is substantial. Why? Because the mint typically produced only a handful of strikes in precious metals, often as trial pieces to test the dies or as special presentations. The silver strike is not merely a variant; it is an entirely different animal in the eyes of the market.

To put this in perspective, here is how metal composition typically affects numismatic value for French patterns:

1. Nickel or bronze (standard strikes): These form the “base” market. Prices can range from modest to significant depending on rarity and condition.
2. Silver strikes: Typically command a 3x to 10x premium over nickel equivalents, assuming comparable rarity and condition.
3. Gold strikes: These are the pinnacle. Gold essais of French patterns can reach five or six figures, and they appear at auction only rarely.

The “Unlisted in Mazard” Premium

Perhaps the most exciting detail in this acquisition is the collector’s observation that the obverse design is “unlisted in Mazard.” For those unfamiliar, the Mazard reference is one of the standard catalogs for French coinage, and an unlisted variety represents something that may be entirely new to the numismatic community. In my career, I have seen unlisted varieties command extraordinary premiums—sometimes 5 to 10 times what a listed equivalent would bring—because they represent genuine discoveries. Collectors who specialize in completing type sets or who pursue die varieties will pay almost anything for a piece that fills a gap in the known record.

The Grading Dilemma: PCGS vs. Raw

An important subplot in this acquisition is the grading situation. The collector notes that the silver Pillet essai was not PCGS graded like most of the other lots, speculating that “it may have graded Details, so they cracked it.” This is a common scenario with rare patterns and essais. When a coin is extremely rare, the population reports at PCGS and NGC may show zero or one examples. If a coin comes back with a “Details” grade—meaning it has some issue like cleaning, tooling, or environmental damage—the owner may choose to remove it from the holder and sell it raw, hoping that collectors will value the rarity over the technical grade.

This creates a fascinating market dynamic:

• PCGS/NGC certified coins provide a safety net for buyers and typically command a 20% to 40% premium over raw equivalents.
• Raw coins of extreme rarity can sometimes sell for more than certified examples because the buyer is purchasing the coin, not the grade. If the coin is unique or nearly so, the grade becomes almost irrelevant.
• The “Details” risk is real, however. A Details-grade coin may have underlying issues that affect its long-term value and liquidity.

In this case, the collector made a calculated decision to pay “retail”—meaning full market price—for an ungraded coin because the rarity justified the risk. This is exactly the kind of judgment call that separates experienced collectors from novices.

The Comparison Set: Silver and Gold Strikes in Context

The collector helpfully provides images of silver and gold strikes already in their collection, graded NGC 62 and NGC 64 respectively. These pieces represent what they describe as the “common” design—the one most often seen in nickel, cataloged as Mazard-2149. The fact that even the “common” design exists in silver and gold tells us something important about the depth of this collecting area.

Let me contextualize these grades:

• NGC 62 (Choice Uncirculated): A solid, attractive coin with minor marks or hairlines. For a rare silver essai, this grade might represent the typical surviving quality.
• NGC 64 (Choice to Gem Uncirculated): A premium example with strong eye appeal. In the pattern market, a 64 can command a significant premium over a 62, especially if the strike is full and the surfaces are clean.

The collector also draws a fascinating connection to the Pillet pattern design for Mexico, which they also own. This cross-referencing is a hallmark of advanced collecting. Engravers like Pillet often worked across national boundaries, and their designs for one country sometimes influenced or paralleled their work for another. For the market value analyst, these connections matter because they expand the potential collector base—a Pillet Mexico pattern might attract both French and Mexican coin specialists, driving competition and prices upward.

Market Dynamics: What Drives Prices Up (and Down)

Based on my analysis of this auction and the broader market for French patterns and essais, here are the primary factors that drive value in this segment:

Factors Driving Value Up

1. Extreme rarity: The fewer known examples, the higher the price. A unique or nearly unique piece can command almost any price.
2. Unusual metal composition: Silver strikes of normally nickel issues, or gold strikes of normally silver issues, carry enormous premiums.
3. Unlisted varieties: Pieces not found in standard references like Mazard are discoveries that collectors will pay dearly for.
4. Provenance and pedigree: A coin from a famous collection or with documented auction history adds tangible value.
5. High grade and eye appeal: For patterns and essais, even a point or two on the Sheldon scale can mean a difference of thousands of dollars, particularly when paired with original luster and an attractive patina.
6. Historical significance: Patterns tied to important historical moments or transitions in French monetary policy carry added interest.
7. Competition at auction: When two or more determined collectors want the same piece, prices can escalate far beyond rational expectations.

Factors Driving Value Down

1. Condition issues: Cleaning, corrosion, scratches, or other damage can reduce value by 50% or more.
2. Lack of certification: Raw coins, especially those that might grade “Details,” carry a discount.
3. Market saturation: If multiple examples of the same issue appear at auction simultaneously, prices can soften.
4. Economic downturns: The high-end numismatic market is sensitive to broader economic conditions. In recessions, discretionary spending on rare coins often declines.
5. Shifting collector interests: If the collecting community moves away from a particular area—say, from French patterns to Chinese modern issues—prices can stagnate or decline.

Investment Potential: Should You Be Buying French Patterns?

This is the question I get asked most often, and my answer is always nuanced. French patterns and essais represent a high-risk, high-reward segment of the numismatic market. Here is my honest assessment:

The bull case: French patterns are among the most beautiful and historically rich coins in the world. The supply is fixed—no more will ever be produced—while the global collector base is growing, particularly in Asia and the Middle East. As wealth increases in these regions, demand for high-quality world coinage is likely to rise. Patterns and essais, with their limited populations and artistic appeal, are well positioned to benefit.

The bear case: This is a thin market. Unlike Morgan Dollars or Gold Eagles, where you can find comparable specimens at multiple dealers and auctions every month, French patterns trade infrequently. This means that liquidity is low—if you need to sell quickly, you may not get full value. Additionally, the market is highly dependent on a small number of dedicated collectors. If several of these collectors pass away or lose interest, demand could drop sharply.

My recommendation: If you are a collector first and an investor second, French patterns and essais are an outstanding area to pursue. Build a collection that tells a story—whether it is the evolution of French Republican design, the work of a specific engraver like Pillet, or the monetary history of a particular reign. A well-curated collection will always hold more value (both financially and intellectually) than a random accumulation of expensive coins. But if you are purely seeking short-term investment returns, look elsewhere. This market rewards patience, knowledge, and passion.

Actionable Takeaways for Buyers and Sellers

Whether you are looking to buy your first French pattern or considering selling a piece you have held for years, here are my key recommendations:

For Buyers:

• Do your homework. Study the Mazard catalog and other references thoroughly. Know what is common and what is rare before you bid.
• Attend major auctions. MDC Monaco, Palombo, and NGSA are the premier venues. Even if you do not bid, attending (or following online) gives you invaluable market intelligence.
• Do not fear raw coins—but be cautious. An ungraded rarity may be a bargain, but have a plan for getting it authenticated and, if appropriate, certified.
• Build relationships with dealers. The best pieces often sell privately before they ever reach auction. A trusted dealer who knows your interests can give you first look at important material.
• Set a budget and stick to it. The “fat checkbook” mentality is real, and auction fever is a powerful force. Decide your maximum bid in advance and do not exceed it.

For Sellers:

• Get professional grading. For PCGS-eligible coins, certification almost always adds value. For extremely rare pieces where the population is zero, consider whether a “Details” grade might actually hurt more than it helps.
• Choose the right venue. A unique Pillet silver essai belongs at MDC Monaco or a similar high-end auction, not on eBay or at a local coin show.
• Document everything. Provenance, prior auction appearances, and any published references to your coin all add value.
• Time the market. If possible, sell when similar material is performing well. Auction results are public—use them to identify trends.

The Bigger Picture: Why This Market Matters

The discussion in this forum thread is about more than just one collector’s acquisitions. It is a window into a market segment that represents the very best of what numismatics has to offer: beauty, history, rarity, and intellectual challenge. French patterns and essais are not just coins—they are artifacts of a nation’s artistic and monetary evolution. Each piece tells a story about the engraver who designed it, the mint that struck it, and the historical moment that inspired it.

The collector who shared their acquisitions in this thread is doing something that I deeply respect: they are building a collection with a clear vision and a deep understanding of the material. They know the difference between a common nickel strike and a rare silver variant. They understand the significance of an unlisted Mazard variety. They recognize the connection between Pillet’s French and Mexican work. This is the kind of knowledge that not only produces a great collection but also protects the collector from overpaying or buying problem coins.

Conclusion: The True Value of French Patterns and Essais

So what is the real value of these pieces? The answer, as always in numismatics, is that a coin is worth what someone will pay for it. But we can say with confidence that the market for French patterns and essais is strong, driven by a combination of fixed supply, growing global demand, and the sheer beauty and historical importance of the material. The Pillet silver essai described in this thread—unlisted in Mazard, struck in an unusual metal, and representing a design previously unknown to the collector—is exactly the kind of piece that will always find a buyer at a strong price.

For those considering entering this market, my advice is simple: educate yourself, buy the best you can afford, and collect with passion. The “fat checkbook” may be necessary for the truly exceptional pieces, but the rewards—financial, intellectual, and aesthetic—are well worth the investment. French patterns and essais represent one of the last great frontiers in numismatics, where new discoveries are still being made and where a single coin can rewrite the reference books. That is a market worth watching, and for the fortunate few, worth participating in.
