Specifications and Physical Details of the Republic of China Year 21 (1932) "Three Birds" Coin
For professional collectors, understanding the physical data of an item is the first step in appraising it. This short-issued silver dollar represents the high standard of craftsmanship at the Central Mint in Shanghai at that time. Below are the standard specifications for this edition of the silver coin, which can be used for basic comparisons of the weight and dimensions of Republic of China Year 21 silver coins:
| Authentication and Testing Item | Standard Data and Feature Description | Collection Reference Value |
| Year and Place of Minting | Republic of China Year 21 (1932) / Central Mint, Shanghai | Deep historical significance due to the special era leading up to the outbreak of the Sino-Japanese War. |
| Metal Material Ratio | Silver coin (Standard fineness: approx. 88% silver, 12% copper) | Ensures hardness while retaining the soft metallic luster unique to silver. |

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 the coin collecting market, many counterfeits produced with modern high-imitation techniques have appeared. To protect your rights, mastering the correct identification techniques for genuine Republic of China Year 21 "Three Birds" coins is 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 genuine Sun Yat-sen "Small Head" Junk Coin using 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.
