藏品名稱：民國二十一年金本位伍圓
此枚中華民國二十一年金本位幣伍圓，于民國二十一年（1932年）上海中央造幣廠鑄。直徑為4.5.44mm，重37.2g,厚2.93mm,錢幣正面孫中山左旁邊面肖像，上環鑄有“中華民國二十一年”字樣， 錢幣背面為雙帆船航行于海面，上環鑄有“金本位幣伍圓”六字，帆船左側為海上日出和九條芒線，海面為三只低飛的海鷗。金本位即金本位制 （Gold standard），金本位制就是以黃金為本位幣的貨幣制度。在金本位制下，每單位的貨幣價值等同于若干重量的黃金（即貨幣含金量）；當不同國家使用金本位時，國家之間的匯率由它們各自貨幣的含金量之比——金平價來決定。金本位制于19世紀中期開始盛行。
此枚錢幣保存較好，其色澤自然，不論是文字還是圖案，都顯得自然細膩，深淺合適。孫中山頭像更是栩栩如生，銀元散發出一股王者的風范和歷史沉淀的氣息，設計新穎，鑄工精湛。采用民國二十一年意大利版樣幣圖案，所有樣幣鋼模均由美國費城造幣廠雕刻，并鑄造少量樣幣。隨后美方將鋼模和樣幣一同交付民國政府。由于局勢變化，各國相繼取消金本位制，所以金本位幣發行計劃終止，在國內并未進行鑄造發行，金本位幣之所以名氣大是由于他的歷史性和稀有性決定的。民間極少有此枚珍品錢幣的藏家，實屬難得不可多見。
In 1932, the Shanghai Central Mint made this five yuan annuity standard currency. The coin has a diameter of 4.5.44mm, a weight of 37.2g and a thickness of 2.93mm. On the front side of the coin is a portrait of Sun Yat Sen on the left side. On the upper ring is the inscription "the 21st year of the Republic of China". On the back of the coin, there are two sailing boats sailing on the sea, and the upper ring is marked with "five yuan gold standard currency". The left side of the sailboat is sunrise and nine awn lines, and the sea surface is three low flying seagulls. The gold standard is the gold standard, and the gold standard is the monetary system based on gold. Under the gold standard, the value of each unit of money is equal to some weight of gold (i.e. the gold content of the currency); when different countries use the gold standard, the exchange rate between countries is determined by the ratio of the gold content of their respective currencies, the average price of gold. The gold standard began to prevail in the mid-19th century.
This coin is well preserved, and its color is natural. Both the text and the pattern are natural and delicate, and the depth is appropriate. Sun Yat Sen's head is even more lifelike. The silver dollar exudes the style of a king and the breath of historical precipitation. The design is novel and the casting is exquisite. All the steel dies were carved by the mint in Philadelphia, USA, and a small number of samples were minted. Subsequently, the US side delivered the steel mould and the sample coin to the government of the Republic of China. Due to the change of the situation, many countries cancelled the gold standard one after another, so the issuance plan of gold standard currency was terminated, and it was not issued in China. The reason why the gold standard currency is famous is because of its historical and rare nature. There are few collectors of this precious coin among the people, which is rare.
