Smart Buying Guide: How to Buy Japan 1870 1 Yen Type 1 圓 銀 Right JNDA 01-9A Without Getting Ripped Off

Historical Significance

The Japan 1870 1 Yen Type 1 圓 銀 Right JNDA 01-9A stands as a testament to Japan’s transformation during the Meiji Restoration. Following the restoration, Japan embraced a modern decimal-based monetary system modeled after Western practices, replacing centuries-old currency traditions. The 1870 1 Yen coin was among the first silver coins produced under this new system, marking Japan’s entry into the global economy.

The Type 1 designation refers to the first design iteration of the 1 Yen coin, featuring the character “圓” (yen) prominently displayed. What makes the Type 1 圓 銀 Right particularly interesting is the countermark or counterstamp of “銀” (gin, meaning silver) placed on the right side of the coin. This marking was applied at the Tokyo Mint, distinguishing it from coins with the gin mark on the left side, which were stamped at the Osaka Mint.

Understanding the historical context is crucial for collectors, as these coins represent Japan’s modernization efforts during the early Meiji period. The 1870 1 Yen coins were produced during a time of rapid economic and political transformation, making them historically significant artifacts that reflect Japan’s emergence as a modern nation-state.

Identifying Key Markers

When examining a Japan 1870 1 Yen Type 1 圓 銀 Right coin, several key markers distinguish it from other varieties:

• Type 1 Design: Features the “圓” character prominently displayed on the obverse
• Gin Countermark: The character “銀” stamped on the right side of the coin
• Right Placement: Specifically indicates the gin mark is on the right side (distinguishing it from left-marked varieties)
• Year: 1870 (Meiji 3 in the Japanese calendar)

The critical distinction between Type 1 圓 銀 Right and other varieties lies in the placement of the gin countermark. According to expert analysis from the forum discussion, coins with the gin mark on the right were stamped at the Tokyo Mint, while those with the mark on the left came from the Osaka Mint. This mint distinction is significant because the Tokyo Mint produced approximately 1 million coins with the right-side gin mark, compared to about 10 million coins with the left-side mark from Osaka.

This 10:1 production ratio makes the Type 1 圓 銀 Right variety considerably rarer than its left-marked counterpart. However, forum participants noted an interesting anomaly: the survival rate appears to be opposite to what one might expect based on original mintage figures, with fewer right-marked specimens surviving despite their lower original production numbers.

Where to Buy

For collectors seeking to acquire a Japan 1870 1 Yen Type 1 圓 銀 Right, several venues offer opportunities, each with distinct advantages and considerations:

Major Auction Houses

Heritage Auctions, Stack’s Bowers, and Stephen Album Rare Coins regularly feature Japanese silver yen in their world coin auctions. These venues typically offer authentication services and professional cataloging, though premiums can range from 15-20% above the hammer price. The forum discussion mentioned a VF or XF Details 1870 with gin selling for over $1,000 at Stephen Album auction, demonstrating the potential value of these coins in major auction settings.

Specialized Japanese Coin Dealers

Dealers specializing in Asian numismatics often maintain relationships with collectors in Japan and may have access to better specimens. These specialists typically provide more detailed provenance information and can offer expertise on subtle variety distinctions that generalist dealers might miss.

Online Marketplaces

Platforms like eBay and specialized numismatic forums can yield opportunities, particularly for collectors willing to do their own authentication research. However, exercise extreme caution with online purchases, as the forum discussion revealed instances of coins selling for as low as $160 at auction, though described as “very ugly looking.”

International Coin Shows

Major coin shows like the World’s Fair of Money or the Hong Kong International Coin Convention often feature dealers with Japanese material. These venues allow for in-person examination and direct negotiation opportunities.

Red Flags to Watch For

Counterfeit Warning Signs

Given the value and rarity of the Type 1 圓 銀 Right variety, counterfeit specimens do exist. Key warning signs include:

• Incorrect font or style of the “圓” and “銀” characters
• Improper metal composition or incorrect silver content
• Artificial aging or toning that appears inconsistent with genuine specimens
• Countermarks that appear stamped rather than applied during the original minting process

Altered or Damaged Coins

The forum discussion mentioned “non details grade” coins selling for premium prices, but collectors should understand what constitutes acceptable condition. Red flags include:

• Evidence of cleaning or harsh cleaning methods
• Holed or mounted coins (unless historically significant)
• Significant scratches, dents, or other damage that affects eye appeal
• Questionable repairs or restoration attempts

Misrepresentation of Variety

Some sellers may incorrectly identify or deliberately misrepresent the variety. The forum discussion clarified that the right/left designation specifically refers to the gin countermark placement, not other design elements. Verify that sellers understand these distinctions before purchasing.

Negotiating Tips

Research Market Values

Based on forum discussions, prices for Type 1 圓 銀 Right specimens vary significantly based on condition and eye appeal. While “ugly” specimens might sell for around $160, better examples can command prices “couple times higher” than specimens without the gin mark. Understanding recent auction results and dealer asking prices provides leverage during negotiations.

Leverage Condition Issues

Coin grading services like PCGS and NGC provide population reports that can support your negotiating position. The forum noted that PCGS population data shows 28 total Right specimens versus 17 Left specimens, which contradicts the expected survival rate based on original mintage. Use this information to question pricing that doesn’t align with rarity data.

Bundle Purchases

If you’re collecting multiple Japanese silver yen varieties, dealers may offer better pricing on multiple purchases. The rarity of the Type 1 圓 銀 Right makes it a cornerstone piece for many collections, and dealers recognize its importance to serious collectors.

Consider “Details” Grade Coins

The forum discussion mentioned that “non details grade” coins with the gin mark are particularly collectible. Coins with minor issues that receive “details” grades from grading services can offer significant savings while still being historically important specimens. However, ensure that any issues don’t significantly impact the coin’s historical or aesthetic value.

Raw vs. Slabbed: Making the Right Choice

Advantages of Slabbed Coins

Professional grading provides authentication and condition verification, which is particularly important for rare varieties like the Type 1 圓 銀 Right. Third-party grading services like PCGS, NGC, and ANACS offer:

• Authentication by expert numismatists
• Protection within tamper-evident holders
• Third-party condition assessment
• Population data that helps establish rarity

The forum discussion referenced PCGS population data, demonstrating how grading service statistics can inform collecting decisions and help establish market values.

When Raw Coins Make Sense

For experienced collectors with authentication expertise, raw coins can offer value opportunities. Consider raw purchases when:

• You have extensive experience authenticating Japanese silver yen
• The price differential between raw and slabbed specimens is substantial
• You’re working with a trusted dealer who offers return privileges
• You plan to submit the coin to a grading service yourself

Authentication Considerations

Whether buying raw or slabbed, authentication remains paramount. For the Type 1 圓 銀 Right variety, focus on:

• Verifying the correct placement and style of the gin countermark
• Checking for appropriate silver composition and weight
• Examining die characteristics specific to 1870 Type 1 yen
• Confirming the coin’s diameter and edge characteristics match known specifications

Investment Potential

Current Market Dynamics

According to forum participants, the Type 1 圓 銀 Right variety is “very collectible” and commands prices “couple times higher” than specimens without the gin mark. The discussion suggests that as more collectors recognize the rarity and historical significance of these coins, prices could increase substantially.

Future Growth Factors

Several factors suggest potential appreciation for the Type 1 圓 銀 Right:

• Limited original mintage from Tokyo Mint (approximately 1 million vs. 10 million from Osaka)
• Increasing interest in Japanese numismatics among international collectors
• Historical significance as one of Japan’s first modern silver coins
• Distinctive countermark variety that appeals to specialized collectors

Risk Factors

While the investment potential appears strong, collectors should be aware of risks:

• Counterfeit specimens in the marketplace
• Market volatility in world coin collecting
• Potential for new discoveries that could affect rarity assessments
• Dependency on continued collector interest in Japanese numismatics

Conclusion

The Japan 1870 1 Yen Type 1 圓 銀 Right JNDA 01-9A represents one of the most intriguing and valuable varieties in Japanese silver yen collecting. Its combination of historical significance, relative rarity, and distinctive countermark placement makes it a cornerstone piece for serious collectors of Japanese numismatics.

Success in acquiring this variety requires careful research, authentication expertise, and strategic purchasing decisions. Whether you choose slabbed specimens for security or pursue raw coins for potential value, understanding the market dynamics, recognizing red flags, and employing effective negotiation strategies will help you build a collection that combines historical importance with investment potential.

As forum participants noted, the market for these coins is evolving, with increasing recognition of their rarity and significance. The discrepancy between expected and actual survival rates adds an element of mystery that makes collecting these coins even more compelling. For collectors willing to do their homework and exercise patience, the Type 1 圓 銀 Right offers both historical satisfaction and the potential for long-term appreciation.
