On-the-Spot Authentication: Key Techniques for Identifying Genuine Republic of China Year 21"Three Birds"Coins

As the"Sun Yat-sen Three Birds Coin"continues to be highly sought after in thecoin collecting market, many counterfeits produced with modern high-imitation techniques have appeared. To protect your rights, mastering the correctidentification techniques for genuine Republic of China Year 21"Three Birds"coinsis crucial. Here are several professional authentication tips:

Micro-details of Calligraphy and Design: On genuine coins, the hair strands of Sun Yat-sen's portrait on the obverse are vivid and three-dimensional, and his eyes are deep; the"three birds"on the reverse are depicted in a light, flying posture, and the lines of the rising sun's rays (radiant lines) are uniformly thick and distinct. Counterfeits, when sand-cast or high-pressure minted, often show adhesion at the intersections of the sun's rays, or blurred edges on the seagulls'wings.
Observe Toning and Silver Luster: After nearly a century, genuine coins develop a natural, richly layered"patina of circulation"or"rainbow toning."Overly thick or brightly colored chemical toning is usually used to conceal traces of counterfeiting. Genuine coins have a soft underlying luster, often described as"high Run Ze Du"(high luster/sheen).
Listen to the Sound and Tapping Resonance: When lightly tapping a genuineSun Yat-sen"Small Head"Junk Coinusing a professional method, it will emit a clear, prolonged, and soft pure silver resonance sound; if the sound is too sharp or dull and short, it is highly likely to be an alloy counterfeit.
