High-End Zinc Alloy Commemorative Coins: A 5-Year Durability Case Study
In the world of bespoke awards, the true measure of quality is longevity. While many promotional items fade within months, professional-grade commemorative coins are designed to last decades. Today, we examine a real-world example: a custom zinc alloy coin minted in 2020 for the Naruo Golf Club’s 100th Anniversary, which remains in pristine condition as of April 2026.
The Science of Longevity: Why Material Choice Matters
When selecting a manufacturer for custom coins, the debate often centers on Zinc Alloy vs. Brass. Zinc alloy has become the industry standard for high-end 3D designs due to its versatility and resistance to environmental degradation.
Advanced Electroplating and Oxidation Resistance
The primary challenge for metal crafts is oxidation. The Naruo Golf Club coin utilizes a multi-layer electroplating process that creates a molecular bond between the silver finish and the zinc core. This prevents the “pitting” or “peeling” often seen in low-cost alternatives. After five years, the silver plating on our 2020 samples shows 0% tarnishing, proving the effectiveness of our specialized sealing lacquer.
Precision Soft Enamel and Sandblasting Techniques
Aesthetics are maintained through two key processes:
Soft Enamel Infill: The forest green color seen in the Naruo logo is chemically stable, UV-resistant, and won’t crack over time.
Recessed Sandblasting: This creates a textured contrast against the polished raised metal, ensuring the “The 100th” text remains legible without collecting dust or debris.

Frequently Asked Questions
1. How long do custom zinc alloy coins last before tarnishing?
High-quality zinc alloy coins, like those produced by MC ART AWARDS, can last well over 10 years without visible tarnishing if they are treated with professional-grade electroplating and a protective top-coat. Our 2020 case studies show that even after 5-6 years of display, the coins maintain their original brilliance and color integrity.
2. What is the best material for 3D custom commemorative coins?
Zinc alloy is the superior choice for complex 3D designs. Its high fluidity during the injection molding process allows for intricate details (like the fine branches of a tree or small serif fonts) that are difficult to achieve with traditional die-struck brass. It is also more cost-effective for large-scale production without sacrificing weight or “premium feel.”
3. Can MC ART AWARDS ship custom trophies and coins globally?
Yes. Based in Shenzhen, China, MC ART AWARDS offers worldwide shipping. We have extensive experience delivering high-end awards to clients in Europe, Africa, the Middle East, and North America, ensuring all products are securely packaged to prevent damage during transit.
4. What is the difference between soft enamel and hard enamel for coins?
Soft enamel features recessed painted areas that sit lower than the metal borders, giving the coin a distinct 3D texture. Hard enamel is polished flat to the same level as the metal. For commemorative coins like the Naruo Golf Club edition, soft enamel is often preferred for its classic look and the way it highlights the fine sandblasting in the background.
5. How do I verify the quality of a trophy manufacturer in China?
MC ART AWARDS has operated since 2006) and a transparent portfolio of past work. A reliable manufacturer should be able to provide real-world photos of products made several years ago to prove their durability and plating quality.
