This fact is a critical point that collectors and investors should constantly be vigilant about.

Meticulously crafted counterfeits can deceive even experts, undermining market credibility and causing substantial financial loss to buyers. At ITTENDO, we don't just report on market trends; we delve into the tendencies of counterfeits, offer concrete knowledge for discerning authenticity, and highlight key points for value assessment, so readers can face the world of coins safely and wisely. We hope to help you develop an eye for discerning the true value of coins and protect your collection from the threat of counterfeits.

The Facts and Trends of Counterfeits Troubling the Market

In recent years, the circulation of counterfeit coins has become a severe issue in the coin market. The proliferation of online auction sites and flea market apps has made transactions between individuals easier, leading to more cases where sellers or buyers without expert knowledge inadvertently get involved with counterfeits. For instance, there have been reports of famous Edo period gold coins being massively produced by overseas counterfeit groups and infiltrating the Japanese market.

These counterfeit coins are intricately made to mimic material, weight, dimensions, stamps, and even the effects of aging. Particularly notable are "altered coins," where slight modifications are made to genuine coins to increase their value, which also requires caution as a broad form of counterfeit. Examples include polishing the surface to enhance appearance or adding non-original stamps. Such counterfeits or altered coins are sold at high prices, targeting collectors without knowledge, threatening market integrity.

Specialized authenticity assessment institutions struggle daily to cope with ever-evolving counterfeiting technologies. The advancement of digital technology enables the production of high-resolution replicas, making it difficult to discern just through traditional methods. Under these circumstances, it is essential for everyone involved with coins to be aware of the dangers of counterfeits and acquire appropriate knowledge and countermeasures.

Understanding the Background of Coin Counterfeiting

The issue of counterfeits in the coin market stems from a complex interplay of various factors. Here, we will delve into its background from the perspectives of beginners, intermediates, and advanced collectors to foster a multifaceted understanding.

【For Beginners】

What factors determine value? Why does value differ despite similar appearances?

The value of coins is determined by their rarity, condition (grade), historical background, and demand. Especially coins with limited existing numbers or in exceptionally good condition are traded at extremely high prices. This "high price" aspect is a major attraction for counterfeiters. Therefore, coins susceptible to counterfeiting are those with "high market value." For instance, rare koban as detailed in Edo Gold Coins (Koban, Ōban) Overview can hold values exceeding several million to tens of millions of yen, making them lucrative targets for forgery.

Even if they look identical, minor differences can directly impact rarity, resulting in significant value disparities. For example, among the same type of Kan'ei Tsuho coins, differences in the minting period, location, or the mother coin used can lead to "rare pieces" or "scarce pieces" with low existing numbers. Such differences are often hard to discern for amateurs, creating opportunities for counterfeits. Forgers take advantage of these knowledge gaps to emulate high-value scarce pieces with inexpensive materials for profit. Thus, understanding the types and classification system of coins and focusing on minute differences are the first steps in spotting counterfeits.

Supply and demand, recent market trends, and scarcity in certain grade ranges

The distribution of counterfeits significantly impacts the supply-demand balance and market trends of coins. During periods when certain coins are surging in value, there is a tendency for forgeries to flood the market, capitalizing on the demand. This can temporarily create an oversupply situation, exerting downward pressure on the market prices of genuine coins. Counterfeit suspicions can lead to a decline in overall market trust, causing buying hesitations.

Scarcity in specific grade ranges also makes them prime targets for forgery. For example, as explained in Coin Grading Standards and Interpretations, high-grade coins like MS65 can command dramatically higher prices compared to grades MS64 and below. This price differential is targeted by altering genuine MS64 grade coins to appear as MS65 or entirely counterfeiting high-grade appearances for sale. The presence of such counterfeits can distort fair price formation, posing a risk to collectors in misjudging genuine value.

Recent market trends are also crucial. If a coin has rapidly increased in price, the possibility that counterfeits are driving this surge must be considered. Especially when confirming price trends on market charts, any abrupt spikes or unnatural increases in transaction volume warrant careful analysis. Discrepancies in supply-demand balance often reflect the shadows of counterfeits.

【For Advanced Collectors】

Hypotheses on "who is buying", capital flows, and the logic behind price settings

The counterfeit problem in the coin market extends beyond mere counterfeit circulation. There are cases where international forgery rings or crime organizations focused on money laundering are involved. They aim to pass off illegal funds as legitimate transactions by manufacturing and distributing high-value coins. Thus, the perspective of "who is buying" becomes important. If specific buyers repeatedly purchase the same coin at inflated prices, it could be a "self-play" to inflate the price of counterfeits or move funds.

Tracing capital flows is essential for uncovering the real situation of the counterfeit market. The routes through which counterfeits are produced, distributed, and ultimately sold often involve multiple countries or regions. These transactions frequently utilize cash, cryptocurrencies, or elaborate shell companies, making it incredibly difficult to grasp the full picture. The logic behind counterfeit pricing differs from the genuine market. Counterfeiters, while referencing genuine market prices, sometimes set unnatural prices to maximize profit. They target new entrants with limited market knowledge or those eager to acquire high-value items cheaply, presenting appealing "prices."

It is also known that specific forgery techniques are specialized for certain regions or coin types. For instance, a forgery group from a particular country may excel in counterfeit holed coins (Kan'ei Tsuho, Tenpo Tsuho). Knowing such information allows for more strategic authenticity assessment. Understanding the organizational activities behind forgery and the flow of capital is crucial for safeguarding market integrity.

Detecting the Shadows of Counterfeits on Market Charts

The market charts provided by ITTENDO are powerful tools for objectively grasping coin price trends. However, it is important to be aware of counterfeits when interpreting these charts. Pay particular attention to the following points when analyzing data.

Median is the Basic When Observing Price Trends

Individual auction prices fluctuate due to market conditions, sellers' reputations, and buyers' intentions. Consequently, relying on the "median" over a specific period instead of being swayed by particular highs or lows is fundamental for a more accurate sense of the market. If counterfeits or altered items mix into the market, they can sell for exorbitant prices or extremely low amounts, skewing the average or median. Particularly for high-value items, counterfeits selling at low prices may temporarily suggest a market-wide drop, warranting caution.

With Few Transactions, It's Just a "Data Point"

When a specific coin sees very few transactions, the price data shown on charts is merely a "data point." This means that single transaction may not necessarily reflect the broader market trend. For example, as noted in the Modern Gold and Silver Coins (Meiji to Showa) Explanation, rare modern gold coins may only trade a few times a year. In such "thin trades," if a counterfeit sells even once at a high price, that data can falsely inscribe high values in the market chart, potentially leading to misguided future expectations.

Use Expressions like "Thin Trading" or "Timing of Actual Demand"

In thin-traded items, a single auction price greatly influences the market, necessitating cautious judgment. Here, delving into the background of that "point" is vital. Check the seller's credibility, the presence of a certificate, and buyer ratings to determine whether the transaction resulted from genuine demand. Genuine demand refers to transactions done by buyers truly seeking authentic items for collection or investment. Transactions involving counterfeits often have unclear backgrounds, making Basic Knowledge of Coin Auctions essential to gathering information from trustworthy auction houses or dealers.

Market charts are past data and do not guarantee the future. Especially for items at high risk of counterfeiting, analyzing the context behind chart figures regularly leads to more precise judgments.

Common Mistakes by Beginners and How to Avoid Them

Beginners in coin collecting or investing often lack the knowledge and experience required, making them more prone to falling into counterfeit traps. Here, we specifically explain typical beginner mistakes and how to avoid them. Grasping these points will help protect your valuable assets and allow you to enjoy the world of coins safely.

Buying Based on Appearance Alone

Many beginners tend to judge the value of a coin solely based on its "appearance." They often impulsively purchase high-value items with good photo appeal or antique charm without thinking deeply. However, modern counterfeiting techniques are so sophisticated that it is nearly impossible to distinguish some counterfeits just by looking. Cases exist where material, weight, dimensions, stamping details, edge treatment, and even aging-induced rust or patina are meticulously mimicked.

Avoidance Tactic: First, thoroughly learn about the ways to distinguish counterfeits and altered items from reliable sources. If possible, examine the coin in person, using tools like magnifying glasses to scrutinize details. Habitually consult multiple experts, read books, or gather information from trustworthy websites.

Neglecting Appraisals and Authenticity Checks

When buying high-value coins, ignoring the importance of certificates or authenticity assessment processes is another common beginner mistake. Cases exist where potential buyers avoid pre-authenticated coins due to costs or inconvenience, or engage in private transactions without validation. Such actions are highly risky and often result in purchasing counterfeits at high prices, later realizing they hold no value.

Avoidance Tactic: Always opt for coins authenticated by reliable third-party institutions or, if unavailable, plan to have them appraised post-purchase. Understanding the standards and specifications from authoritative grading agencies like NGC or PCGS will offer protection. These grading services provide objective verification of a coin's authenticity and condition and are considered essential in investment. Never make impulsive decisions, and remain willing to invest time and money in due diligence.

Rushing Into High-Value Tiers

Driven by the desire to "profit quickly" or "make a fortune," some beginners dive into buying high-value coins worth tens or hundreds of thousands of yen with little to no knowledge or experience. While attractive, these high-value items carry greater risk and a higher likelihood of being counterfeited. The high-value market is also less liquid, meaning it can be challenging to find buyers when attempting to sell.

Avoidance Tactic: Start with more affordable, diverse items like holed coins (Kan'ei Tsuho, Tenpo Tsuho), and gradually build knowledge and understanding of market dynamics. By accumulating small successes, you will incrementally enhance your experience. Also, consider the proper methods of storing coins during purchase to preserve them safely for the long term. Instead of rushing, progressively gather expertise as a reliable strategy.

ITTENDO's Conclusion: What to Record to Discern Counterfeits

The threat of counterfeits in the coin market is an unavoidable challenge for all collectors and investors. However, possessing the right knowledge and vigilance, along with trustworthy information sources, significantly mitigates this risk, allowing safe enjoyment of the coin world. At ITTENDO, we organize what needs to be recorded to avoid counterfeits.

Graded coins with certifications from trustworthy appraisal institutions (e.g., NGC, PCGS) provide third-party verified authenticity and condition, leaving behind verifiable information. Coins in slab cases issued by these institutions have a low risk of counterfeiting, ensuring safe inclusion in collections. Especially for high-value items, the absence of a certificate can greatly sway their value, making certified items essential.

Avoid reckless high-value investments in specific items showing rapid market price surges. Price spikes might hide counterfeit inflows or speculative movements, posing risks of catching a peak. Confirm multiple data points and scrutinize whether price increases stem from "genuine demand" or suspicious activity. If uncertain elements abound, refrain from purchasing or wisely wait for more reliable information.

When interpreting market charts, apply skepticism to single auction prices within "thin trading" items. Such data may not accurately reflect overall market trends, possibly involving counterfeits or altered coins. Ensure multiple transaction data narratives and stable price medians before making decisions. Investigate deeply into the background of sudden price changes.
