民國雙帆幣是我國近年來機制幣中十分有名氣的一種，之所以名氣大主要就是因為民國雙帆幣所具有的歷史性和珍稀性導致的。據相關資料介紹，這枚錢幣大多是都是在上海中央造幣廠製造而成，目前所保留下來的幣值一般只有壹圓和中圓這兩種。由於當時的國民政府推行的是“法幣”政策，不允許在民間私自流通銀圓幣種，所以使得民國雙帆幣比較少在市面中流通。

國父孫中山：1894年11月24日，孫中山在檀香山創立興中會 [6] 。1905年（光緒三十一年）成立中國同盟會。1911年10月10日（宣統三年）新軍中的革命黨人暗中聯絡，決定當天晚上起義。辛亥革命後被推舉為中華民國臨時大總統（任期1912年1月1日——1912年4月1日）。1925年3月12日，孫中山因癌症在北京逝世。1929年6月1日，根據其生前遺願，葬於南京紫金山中山陵。1940年，國民政府通令全國，尊稱其為“中華民國國父”。
民國二十五年（1936年）孫中山像中圓背布幣銀幣，直齒邊小型樣幣，美國舊金山造幣廠設計雕制鋼模，上海中央造幣廠試鑄之樣幣，民國24年（1935年）國際銀價忽然大漲，中央造幣廠以前所鑄之孫像銀幣銀料價值已高過面值，中方故向美方訂購壹圓及中圓二種幣值銀幣，為防止國人將銀幣私毀或偷運出口，此項代鑄銀圓採用縮小尺寸、減輕重量及降低成色的方法生產，成色皆為72%，後因銀價又迅速回軟，恢復正常，故25年小型銀幣便胎死腹中，只鑄有少量存世。此銀幣設計精美，鑄造精良規範，打製深峻，鏡面底版，原味淡銀灰色包漿，光澤柔和悅目，狀態頂級，品相一流，存世極為罕見，存世屈指可數。
銀幣邊齒規整，十分整齊，而邊齒正是用於防偽，此幣可見壓力十足，為真品無疑。
銀幣壓力：由於清朝自民國使用英國進口造幣機器，壓力高達五十噸，這個技術直到民國結束也未被超越，所以國內仿製銀幣多為圖案模糊不清，內齒相連，並齒，所以很多專業的錢幣收藏者，一看錢幣說是壓力不足，就變相的說是仿品，真品銀幣，圖案清晰，無論是邊齒，還是內次，都十分規整，且不會出現相連，並齒的情況，內齒長短一致，整齊劃一，不會出現長短不一的情況，邊齒也不會有斜齒，或者齒痕極淺的情況，因為仿幣是用一種小型的裝置，圍著銀幣邊緣，滾上一圈，我們稱之為滾齒，很多陰陽齒等特殊齒輪是後滾出來的，在錢幣邊緣形成一圈滾痕，所以我們看錢幣首要的就是看它的壓力是否足夠，線條是否清晰，沒有瑕疵，多餘的痕跡。
這枚銀幣也被稱為‘國父銀幣’，讓後輩能銘記孫中山偉人。這枚銀幣外觀精品，無磕缺，損毀，氧化自然，綢緞底光，經專家鑑定為真品而且是完美品相，錢幣收藏最看重品相，歷經漫長歲月能有如此品相，非常難得，國父幣的收藏價值極高。

The Double sail coin of the Republic of China is one of the most famous mechanism coins in China in recent years.

National Father Sun Yat-sen: On November 24, 1894, Sun Yat-sen founded xing Zhong Hui in Honolulu [6]. 1905 (guangxu thirty-one year) founded the Chinese Tongmeng Hui. On October 10, 1911 (the third year of Xuantong), revolutionary members of the new army secretly contacted each other and decided to rise up that night.

The silver coin is beautifully designed, well cast and standardized, and deep, mirror bottom, plain silver gray patina, soft luster and pleasing to the eye, top state, first-class appearance, extremely rare, very few in existence.
The edge teeth of the silver coin are regular and very neat, and the edge teeth are used for anti-counterfeiting. The currency is under great pressure and is undoubtedly genuine.
Silver coin pressure: Since the qing dynasty republic of China, use the imported version machine, pressure up to 50 tons, the technology until the end of the republic of China, also not be transcended, so domestic imitation silver to design more blurred, internal tooth is linked together, and teeth, so a lot of professional coin collectors, a look at the coin, pressure is not enough, is a disguised form of replicas, genuine silver COINS, the pattern is clear, both side of tooth, Or within time, very neat, and there will not be connected, and teeth, the tooth length is consistent, uniform, there will be no length is differ, there will be no edge of helical, or teeth marks very shallow, because imitation coin is made of a small device, around silver edge, roll in a circle, we call the roll teeth, Yin and Yang are a lot of teeth after special gear is rolled out, A circle of rolling marks is formed on the edge of the coin, so the first thing we look at the coin is to see whether its pressure is enough, whether the lines are clear, there are no defects, and excess traces.
This silver coin is also known as the 'Father of the Nation silver Coin', so that future generations can remember the great man Sun Yat-sen. The appearance of the silver coin is fine, no breakage, damage, oxidation of nature, the bottom light of silk and satin, identified by experts as genuine and perfect product phase, the most important coin collection phase, after a long time can have such a product phase, it is very rare, the collection value of the father of the nation currency is very high.
