Is Your Fivaz-Stanton FS Variety Unattributed? How to Verify, Authenticate, and Spot the Fake Before You Send It In

With counterfeits flooding the market, knowing the specific diagnostic points for this item is critical. As a numismatist who has spent decades navigating the treacherous waters of rare coin authentication, I can tell you firsthand that the allure of an unattributed Fivaz-Stanton (FS) Variety—one that promises a 1/0 pop across PCGS, CACG, or NGC—is intoxicating. But before you send your potentially valuable treasure into the certification arena, you must arm yourself with the diagnostic tools necessary to prove authenticity. Without rigorous testing, even the most promising specimen can be dismissed as a common error or, worse, a sophisticated counterfeit.

In thisAuthentication Guide, we will dissect the essential metrics of coin authentication: weight, magnetic properties, die markers, common fakes, and testing methods. By understanding these diagnostic points, you can confidently evaluate whether your coin warrants the investment required for a Top Certified Public (TPG) attribution.

Understanding the Weight: A Foundation of Numismatic Authentication

When evaluating a coin that could make a 1/0 pop, the first line of defense is its weight. In my experience grading, weight deviations are often the first indicator that a planchet has been altered or that a die adjustment has occurred.

Why Weight Matters in Rare Varieties

Rare varieties, such as the Fivaz-Stanton series, often feature subtle die adjustments that slightly alter the weight of the coin compared to standard strikes. An unattributed variety might weigh fractionally less or more than its standard counterparts due to changes in the rim height or planchet thickness caused by the die state.

However, weight alone cannot authenticate a coin. A common tactic among counterfeiters is to strip the original clad layer and re-anneal the core, or to use a modern, lighter planchet to artificially lower the weight to match the specification of a rare variety. Therefore, weight must be measured with extreme precision.

• Precision is Key: Always weigh your coin on an analytical balance accurate to at least three decimal places (e.g., 9.1250 grams).
• Compare to Standards: Cross-reference your weight against PCGS or NGC population reports for the specific date and mintmark in question.
• Deviations are Red Flags: A variance of more than 0.02 grams from the standard weight is a strong indicator of an altered planchet.

Decoding Magnetic Properties: Beyond the Surface

Another vital diagnostic tool in my authentication toolkit is the evaluation of magnetic properties. Many collectors test coins using simple magnets to check for clad composition anomalies.

Testing for Magnetic Response

Modern clad coins, including many older Fivaz-Stanton issues, consist of outer layers bonded to a inner core. If a coin exhibits a strong magnetic pull, it indicates the presence of a ferromagnetic core (like copper or nickel) rather than a silver core. Counterfeiters frequently use modern steel or iron blanks coated with tin or zinc to mimic the weight of rare specimens, which inadvertently introduces a magnetic anomaly.

Conversely, a coin that is entirely non-magnetic could indicate a heavily worn or damaged clad layer where the core has been exposed. When assessing an unattributed variety, run a neodymium magnet test. A weak pull is normal for clad coins; a strong pull is a significant warning sign.

• Standard Test: Hold a standard refrigerator magnet 2 inches away from the coin. A slight attraction is acceptable; a strong clinging indicates a problem.
• Neodymium Test: Use a neodymium magnet for a more sensitive reading. If the coin clamps onto the magnet, the core composition is likely compromised.
• Post-Certification Checks: Even after a coin receives a certification label, always verify the magnetic properties independently, as some counterfeiters are clever enough to re-coat altered surfaces.

Die Markers: The True Gold Standard of Variety Verification

If there is one diagnostic feature that separates a genuine rare variety from a fake, it is the die marker. In the forum discussion surrounding the Fivaz-Stanton Variety Question, one user noted, “The Pick Up Point is very obvious.” This highlights the absolute necessity of die markers in authenticating unattributed varieties.

Identifying the “Pick Up Point” (PUP)

A Pick Up Point (PUP) is a raised area on the obverse or reverse die that transfers a distinct, often sharp, diagnostic mark to the coin’s surface. TPG attribution experts look for these PUPs obsessively. An obvious PUP suggests a specific die state that TPG’ers recognize as a hallmark of a rare variety.

To identify a PUP, you must examine the coin under 10x to 20x magnification. Look for raised, sharp-edged lines, die cracks, or cuds (raised fragments of the die that break off during striking). The absence of a PUP is often the reason TPG’ers refuse to attribute a variety, as they require undeniable visual proof of a die anomaly.

• Visual Inspection: Examine both sides of the coin under strong magnification. Look for raised lines, die cracks, or die chips.
• Cross-Reference: Compare your die markers against the Cherrypicker’s Guide (CPG). The CPG is the ultimate authority for obscure varieties, and matching the PUP to a documented die state is your strongest argument for TPG attribution.
• Documentation: Capture high-resolution, macro photographs of the PUP from multiple angles. A single blurry photo is insufficient; clear documentation is the currency of TPG attribution.

Beware the Common Fakes: Altered Planchets and Modern Dies

Selling an unattributed variety for a 1/0 pop means you are potentially dealing with a high-value target. Unfortunately, this makes you a prime target for sophisticated fakes. Understanding how counterfeiters operate is crucial to protecting your investment.

How Counterfeiters Mimic Rare Varieties

Counterfeiters employ several techniques to deceive collectors. One method involves using modern steel dies to strike a blank that matches the weight of the rare variety. While the weight might be perfect, the die markers will be entirely wrong, lacking the subtle die cracks or cuds characteristic of the genuine FS variety.

Another common method is chemical etching. Counterfeiters may use acid or lasers to artificially create die cracks or raised lines on a coin’s surface. These etchings often look sharp, clean, and unnatural, failing to replicate the organic wear and tear of genuine die markers. Furthermore, they may strip the original clad layer and re-anneal it, creating a coin that passes the magnetic test but fails the die marker test.

• Sharp, Clean Lines: Genuine die cracks are jagged and irregular; etched lines are usually perfectly straight and overly sharp.
• No Die Wear: Look for signs of die polish or wear patterns around the die marker. Fakes lack the micro-scratches of genuine die use.
• Weight vs. Die Marker Discrepancy: A coin might weigh exactly as expected, but if the die markers do not match the documented FS variety, it is a fake.

Pre-Certification Testing: Equipping Yourself for the Journey

Before you commit the time and money to submit your coin to a TPG service, you must conduct a rigorous pre-certification testing protocol. As the forum discussion highlighted, the burden of proof falls on the collector when seeking an attribution.

Step-by-Step Diagnostic Protocol

In my years of appraising, I have seen countless instances where a coin was sent in for attribution based solely on a shaky, low-resolution photograph. To avoid this, follow this diagnostic checklist:

1. Photography: Use a DSLR or high-end mirrorless camera with a macro lens. Photograph the coin under both natural daylight and consistent artificial lighting. Capture the PUP from at least five angles.
2. Weighing: Weigh the coin on an analytical balance. Document the exact weight and compare it to the PCGS/NGC standard for the specific date and mintmark.
3. Magnetic Test: Perform the neodymium magnet test as described previously. Record the results.
4. Die State Analysis: Compare your high-resolution photos against the Cherrypicker’s Guide. Note any die cracks, cuds, or raised areas that match the FS variety description.

Remember, a TPG attribution is not guaranteed. The experts must believe the variety is significant enough to warrant a registry slot. If your documentation is thorough and the die markers are undeniably clear, you maximize your chances of securing that elusive 1/0 pop.

Navigating the Certification Dilemma: Send It In vs. Hold Onto It

Returning to the original forum thread, the dilemma faced by the collector was whether to submit the coin for TPG attribution. The consensus was that if the variety is truly obvious, the juice is worth the squeeze. However, as noted by one participant, TPG attribution requires more than just a strong image; it requires published recognition of the variety.

The Reality of TPG Attribution

If a variety has never been slabbed with an FS number, it implies it may not be widely recognized by the numismatic community outside of specialized publications like CoinWorld or Wexler’s Coins and Die Varieties. TPG experts are highly selective; they require documented proof that the variety is real and significant before assigning a FS number to a slab.

Therefore, before sending your coin in, ask yourself: Do I have additional documentation beyond the CPG? Have I submitted articles to coin magazines to establish the variety’s legitimacy?

• Actionable Takeaway: If you have large, clear images of the PUP and supporting documentation, submit the coin. The potential value of a 1/0 pop far outweighs the cost of the reholdering fee.
• Cautionary Tale: If the variety lacks broader recognition and you are unsure of its authenticity, hold onto the coin. Sending an unverified variety into the certification pipeline risks wasting your money on a TPG that will ultimately decline the attribution.

The Collectibility and Historical Importance of Unattributed Varieties

An unattributed Fivaz-Stanton variety that makes a 1/0 pop is a once-in-a-collector’s-career opportunity. The historical importance of such a coin lies in its ability to bridge the gap between numismatic theory and physical reality. When a TPG expert attributes a FS variety, they are not just verifying a coin; they are validating a die state that adds a unique chapter to the history of the Fivaz-Stanton series.

Historically, rare varieties drive the market. The price premium for a certified 1/0 pop variety can easily reach hundreds or thousands of dollars, transforming a common circulated coin into a museum-quality piece. However, this premium is entirely dependent on the authenticity of the attribution. A fake FS variety will not appreciate in value because it lacks the historical provenance and die-state uniqueness that genuine varieties possess.

By rigorously applying the diagnostic points of weight, magnetic properties, die markers, and testing methods, you ensure that your coin holds the historical and financial value it deserves. Authenticate with confidence, document meticulously, and let the experts do their job—but only after you have armed yourself with the truth.
