一、历史背景：特殊时代的货币实验
中华民国二十一年（1932年），国民政府为稳定经济、统一货币制度，推行“金本位制”，并委托上海中央造币厂试铸“孙小头伍圆”银币。该币作为金本位制的配套货币，原计划替代传统银元，但因国际银价波动及国内政治局势动荡，最终未正式发行，仅存少量试铸样币。其短暂的历史存在，使其成为民国货币史上极具研究价值的“过渡性货币”，承载着特殊时代的经济探索与政治意图。
二、设计特征：中西合璧的艺术典范
正面设计币面中央为孙中山侧面肖像，由意大利雕刻师乔治·路易奇（L. Giorgi）操刀设计。肖像目光深邃，胡须、发丝等细节刻画入微，展现了西方雕塑艺术的写实风格。肖像上方镌刻“中华民国二十一年”字样，字体端庄大气，彰显国币权威。
背面设计背面以“双帆船”为核心图案，象征国家扬帆远航、经济复兴。帆船上方为初升的太阳，寓意光明与希望；下方为波浪纹饰，展现海洋的磅礴气势。币面边缘镌刻“金本位币伍圆”字样，明确其货币属性。整体设计融合了中国传统吉祥元素（如帆船、太阳）与西方写实技法，形成独特的艺术风格。
工艺细节
材质：采用高纯度银（含银量88%），符合国际银币标准，确保币面光泽持久。

尺寸与重量：直径45mm，厚度2.8mm，重35.5g，符合民国时期银币规范，手感厚重，质感上乘。
三、稀缺性与收藏价值：存世罕见的“币中珍品”
存世量稀少因未正式发行，孙小头伍圆银币的存世量不足百枚，且大部分被海外收藏机构或私人藏家珍藏，国内市场流通极少。其稀缺性远超同期发行的“袁大头”“船洋”等品种，成为钱币收藏界的“顶级珍品”。

I. Historical background: Monetary experiment in a special era
In the 21st year of the Republic of China (1932), the Nationalist Government implemented the "Gold Standard System" to stabilize the economy and unify the monetary system. It commissioned the Shanghai Central Mint to trial-produce the "Sun Yat-sen Head Five Yuan" silver coin. As a complementary currency to the Gold Standard System, this coin was originally planned to replace traditional silver dollars. However, due to fluctuations in international silver prices and domestic political instability, it was ultimately not officially issued, and only a small number of trial-produced samples remain. Its brief historical existence makes it a highly valuable "transitional currency" in the history of Republic of China currency, carrying the economic exploration and political intentions of a special era.
II. Design Features: An Artistic Paragon Combining Chinese and Western Elements
Front design
The center of the coin features a side portrait of Sun Yat-sen, designed by Italian sculptor L. Giorgi. The portrait captures Sun's deep gaze and intricate details such as his beard and hair, showcasing the realistic style of Western sculpture art. Above the portrait is engraved the inscription "Republic of China, Twenty-First Year," in a dignified and grand font, highlighting the authority of the national currency.
Back design
The reverse side features a central pattern of a "double-masted ship," symbolizing the nation's aspirations to sail far and achieve economic revitalization. Above the ship, the rising sun represents light and hope, while below, wavy patterns depict the majestic power of the ocean. The edge of the coin is engraved with the words "Gold Standard Coin Five Yuan," clearly indicating its currency status. The overall design integrates traditional Chinese auspicious elements (such as the ship and the sun) with Western realistic techniques, creating a unique artistic style.
Process details
1. Material: High-purity silver (88% silver content) is used, meeting international silver coin standards and ensuring long-lasting luster on the coin surface.
2. Die-casting: Using imported coinage machines for stamping and forming, the patterns are clear, the edges are neat, and the anti-counterfeiting features are obvious (such as the alternating design of straight teeth and olive teeth).
3. Size and weight: With a diameter of 45mm, a thickness of 2.8mm, and a weight of 35.5g, it conforms to the specifications of silver coins from the Republic of China period. It feels heavy and has a superior texture.
III. Rarity and Collectible Value: A Rare "Rarity in Coins"
The quantity in existence is scarce
Due to its unofficial release, the Sun Xiaotou Wu Yuan silver coin has a circulation of less than 100 pieces, and most of them are treasured by overseas collection institutions or private collectors, with very few circulating in the domestic market. Its rarity far exceeds that of coins issued during the same period, such as the "Yuan Datou" and "Chuanyang", making it a "top-tier treasure" in the numismatic collection community.
Auction market performance
In 2024, a well-preserved Sun Yat-sen Five Yuan Silver Coin sold for RMB 2.6 million at the Yachang auction, setting a record for the auction of similar silver coins.
investment potential
As the numismatic collection market heats up, the scarcity of high-end silver coins will further drive up prices. The Sun Yat-sen Five Yuan Silver Coin, as a "unique item" in the history of Republic of China currency, possesses both cultural and investment value. It still has potential for appreciation in the long run and is the preferred choice for experienced collectors and investors.

IV. Condition and Authentication: Core Elements of Authenticity Guarantee
Appearance rating
This silver coin has a natural patina, a warm and lustrous color, with clear and unabraded text and patterns, and neatly formed edges. It meets the PCGS (Professional Coin Grading Service) MS65 standard and falls within the category of "Extremely Fine" coins, making it extremely rare in market circulation.
Authenticity identification
1. Pattern details: The portrait beard and hair of the real coin are delicate, and the wave pattern of the sailboat is distinctly layered; the counterfeit coin, due to insufficient mold precision, has a blurred pattern and missing details.
2. Edge tooth characteristics: The edge teeth of genuine coins feature an alternating design of straight and olive teeth, which are neat and symmetrical; the edge teeth of counterfeit coins are rough and irregular in shape.
3. Patina state: The patina of genuine coins is formed through long-term natural oxidation, resulting in a soft and mellow color; the patina of counterfeit coins is mostly artificially aged, with a dull color that is prone to fading.
4. Weight and purity: The genuine coin weighs 35.5g and contains 88% silver; the counterfeit coin exhibits significant weight deviation and lacks purity.
V. Recommendation Reason: A Dual Choice for Collection and Investment
1. Historical value: As a trial coin of the Republic of China's gold standard system, its design and casting reflect the highest level of China's monetary system at that time, making it an important material object for studying the economic history of the Republic of China.
2. Artistic value: The design style that combines Chinese and Western elements showcases the innovation and breakthroughs in coin art during the Republic of China period, possessing extremely high aesthetic value.
3. Rarity: With a circulation of less than 100 pieces, it is rarely seen in the market and is considered a "top-tier treasure" in the numismatic community.
4. Investment Potential: The auction market is performing strongly, with immense long-term appreciation potential, making it an ideal choice for seasoned collectors and investors.
