Japan 1870 1 Yen Type 1 圓 銀 Right: A Coin Ring Artisan’s Perspective

Introduction: The Art of Coin Jewelry Crafting

Not every coin is suitable for crafting into jewelry. As a coin ring artisan, I carefully evaluate each piece based on metal composition, durability, and aesthetic appeal. Today, we’ll examine the Japan 1870 1 Yen Type 1 圓 銀 Right (JNDA 01-9A) to determine its potential for transformation into beautiful, wearable art.

Historical Significance of the 1870 1 Yen Type 1

The 1870 1 Yen coin represents a pivotal moment in Japanese monetary history. Following the Meiji Restoration, Japan was modernizing its currency system, moving away from the complex Tokugawa coinage to a more standardized decimal system. The 1870 1 Yen was among the first silver coins produced under this new system, making it historically significant for collectors and crafters alike.

Metal Composition and Silver Content

The 1870 1 Yen Type 1 is composed of .900 fine silver, containing approximately 0.7874 troy ounces of pure silver. This high silver content makes it an excellent candidate for jewelry crafting. The coin’s substantial weight and density provide a satisfying feel when worn as a ring or pendant.

The silver composition offers several advantages for jewelry making:

• Excellent workability – silver is malleable enough to shape without excessive force
• Beautiful luster that polishes to a high shine
• Hypoallergenic properties, making it suitable for sensitive skin
• Natural tarnish resistance when properly sealed

Design Details and Aesthetic Appeal

The obverse features a striking dragon design with intricate scales and flowing mane, surrounded by Japanese characters. The reverse displays the denomination encircled by floral motifs. These detailed designs translate beautifully when the coin is transformed into a ring, creating a unique texture and pattern that wraps around the finger.

The “Right” designation refers to the placement of the “銀” (silver) countermark, which was stamped in Tokyo Mint. This countermark adds an additional layer of visual interest and historical significance to the piece. The contrast between the original design and the countermark creates a compelling aesthetic that many collectors and jewelry enthusiasts find appealing.

Metal Hardness and Durability Considerations

Silver’s Mohs hardness of 2.5-3 makes it relatively soft compared to other metals commonly used in jewelry. However, this softness is actually advantageous for coin ring crafting:

• Easier to shape and form without specialized equipment
• Less likely to crack or split during the crafting process
• Allows for intricate detailing to be preserved

For daily wear, the coin may require periodic polishing to maintain its shine. A protective coating can be applied to preserve the finish and prevent tarnishing.

Countermark Variations: Left vs. Right

The 1870 1 Yen Type 1 exists with the “銀” countermark on either the left or right side of the dragon design. The right-side countermark (Tokyo Mint) is significantly rarer than the left-side (Osaka Mint), with an estimated mintage ratio of 1:10. This rarity adds value and collectibility to pieces crafted from the right-countermark variety.

When crafting jewelry from these coins, the countermark placement creates different visual effects:

• Right countermark: Creates a more asymmetrical, dynamic look when wrapped into a ring
• Left countermark: Offers a more balanced appearance, with the countermark often positioned on the inner band

Crafting Potential and Techniques

The 1870 1 Yen Type 1 is well-suited for various jewelry applications:

Coin Rings

The coin’s diameter (34mm) and thickness make it ideal for men’s rings or statement women’s rings. The detailed dragon design wraps beautifully around the finger, creating a conversation piece that showcases both the coin’s history and the artisan’s skill.

Pendants and Necklaces

The coin can be preserved in its original round shape and bezel-set as a pendant. This method maintains the full design integrity and is perfect for those who prefer to showcase the entire coin.

Earrings

Smaller components of the coin design can be incorporated into drop earrings, allowing for creative interpretations of the dragon motif.

Authentication and Preservation

When selecting coins for jewelry crafting, authentication is crucial. Look for these key markers:

• Clear date (1870) on the obverse
• Sharp countermark details
• Well-defined dragon scales and features
• Proper weight and dimensions

For preservation, consider these tips:

• Apply a jeweler’s clear coat to prevent tarnishing
• Store in anti-tarnish cloth when not worn
• Clean gently with a soft cloth and silver polish as needed

Market Value and Investment Potential

The 1870 1 Yen Type 1 with right countermark commands premium prices in both numismatic and jewelry markets. Recent auction results show:

“With gin mark the price is couple times higher than without gin mark. It is very collectible with gin mark especially with a non-details grade.” – Forum Contributor

This increased value translates to higher-end jewelry pieces, making these coins attractive for both collectors and investors interested in wearable assets.

Conclusion: A Rare Opportunity for Artisans

The Japan 1870 1 Yen Type 1 圓 銀 Right offers exceptional potential for coin ring artisans and jewelry makers. Its historical significance, beautiful design, and rarity (particularly with the right countermark) make it a standout choice for creating unique, valuable pieces. While the soft silver composition requires careful handling, the end result is a wearable piece of history that combines numismatic value with artistic expression.

For collectors and investors, jewelry crafted from these coins represents a unique opportunity to own and wear a piece of Japanese monetary history. As interest in these countermarked varieties grows, the value and desirability of both the raw coins and crafted pieces are likely to increase, making them a compelling choice for those looking to combine their passion for history with wearable art.
