中華民國二十三年孫中山雙帆試鑄幣
試鑄幣
試鑄幣是以檢驗製造流程、設備狀態為目地，驗證產品是否可達到設計目標的實驗幣，我們稱之為試鑄幣。
機制幣的生產，從祖模設計、工具模翻制，從銅料熔鍊，到壓軋銅板、製作銅餅、晃洗、退火、滾邊、印花、質檢、入庫運輸等，前後涉及到的工藝流程有十幾個環節，需要不同技術工種緊密配合，可以說機制幣的生產過程，完完全全就是一個現代工業生產流水線過程。各省開廠造幣，必須經過上級審批通過，大清朝是皇上親自御覽審核批准。這些幣是在“試鑄幣”完成之後，確保流程、機器、設備狀態ok之後，才進行少量製造。
且材質也與試鑄幣、初鑄幣、流通幣不完全相同。要麼是“配料完美”，不能偷工減料；甚至增加工序，出現銅質鍍金、鍍銀；亦或是，直接採用金貴金屬，製作金質樣幣。

中華民國二十三年孫中山雙帆幣試鑄幣
此年號孫中山像試鑄幣錢是民國二十三年上海中央造幣廠所鑄，在幣面的設計方面，雙帆幣是凝聚著千百名工藝技師的智慧源泉和美學獨特視角，品相極好，整體造型和諧，圖案設計精美，因此引得萬千藏家競相收藏。
該錢幣的表面幾乎不見鏽色，而材質為銅鎏銀含銅的比例高於含銀比例，通過光線的對比和折射，我們依然可以看出這對錢幣的銀質斑駁蒼古的“包漿”，這便是自然形成的“時間印記”。
不同的歷史時期總要留下不同的歷史印跡。產自於民國二十三年的孫中山雙帆幣，則成為當時那個特定歷史時期市場上流通的主要幣種之一。讓人值得驚奇的是，該幣種經歷了長達百年之久的磨損，品相依然完好，被民間藏家們所珍藏。價值極高！
此中華民國二十三年雙帆試鑄幣，系民國二十三年上海中央造幣廠所鑄。整幣通體為銅鎏銀鑄造，正面鐫刻著偉大的革命者孫中山先生的正面頭像，材質、品相、包漿完全符合試鑄幣的標準和工藝，且保存完好傳世量極少是不可多得的佳品，極具收藏價值和歷史研究價值。
此款錢幣因鑄有孫中山肖像，且鑄造成的銀元比袁大頭略小，因而被稱為“孫小頭”。中華民國二十三年孫小頭試鑄幣壹圓為官政府製作，由於民國時期戰爭連綿不斷，中華民國二十三年孫小頭壹圓損失較為慘重，試鑄幣本身數量極少且歷經百年曆史，其存世量珍罕，彌足珍貴。
23 Sun Yat-sen double sail test coin test coin is to test the manufacturing process, equipment status as the goal, to verify whether the product can achieve the design goals of the experimental currency, we call it a trial coin. Mechanism of the production of coins, from the Zu Mo design, tool mold, from the copper smelting, to the rolling copper plate, the production of brass cake, shake wash, annealing, piping, printing, quality inspection, warehousing and transportation, the process has involved more than 10 links, need to work closely with different technology, you can say the production process of mechanism coins, Completely is a modern industrial production line process. Each province to open a factory coinage, must pass through the superior approval, the great Qing Dynasty is the Emperor personally preview audit approval. These coins are made after the "trial coin" is completed, ensuring that the process, machine, and equipment status is OK. And the material also with the trial coin, the initial coinage, currency is not exactly the same.

Different historical periods always leave a different historical imprint. Produce from ...
