大清銅幣，學名清代機制銅圓，鑄造始于1900年(清光緒二十六年)，止于1911年(宣統三年)。鑄造流通時間盡管只有十余年，但其鼎盛時期全國共有十七省二十局開機鑄造銅圓。十七二十局先后鑄造的當十銅圓，各不相同，版式繁多。僅以明顯區別劃分，其版式亦有數百種之多。如以細微區別劃分，其版式在千種以上。因此當代銅圓收藏愛好者每每以搜尋不同版式的銅圓為最大樂事。清代機制銅圓版式繁多，尤以當十者為最。清代末期開機鑄造銅圓的十七省二十局，無一不鑄造當十銅圓，而二文、五文、二十文銅圓則僅有部分省局鑄造。故本文所列銅圓收藏方法，僅就當十銅圓而言。
The Qing copper coin, whose scientific name is the mechanism copper coin of Qing Dynasty, was cast in 1900 (the twenty-sixth year of Guangxu in Qing Dynasty) and ended in 1911 (the third year of Xuantong). Although the casting circulation time was only more than ten years, in its heyday, there were 17 provinces and 20 bureaus in China that started casting copper coins. Ten copper coins were successively cast in the 17th and 20th Bureau, which were different and varied in layout. Divided by obvious differences, there are hundreds of formats. If divided by subtle differences, there are more than 1,000 formats. Therefore, contemporary collectors of copper coins often take searching for copper coins with different formats as their greatest pleasure. There are many layouts of mechanism copper circle in Qing Dynasty, especially when it is ten. In the late Qing Dynasty, all the seventeen provinces and twenty bureaus started casting copper coins, all of which were ten copper coins, while only some provincial bureaus cast two, five and twenty copper coins. Therefore, the collection methods of copper coins listed in this paper are only for ten copper coins.
光緒二十六年（1900），李鴻章奏準在廣東開鑄銅元。清銅元主要分為兩大類，在先的一類幣面書“光緒元寶”，在后的一類幣面書“大清銅幣”。除廣東外，先后開鑄的廠局還有福建、湖北、四川、清江等20余局。四川是銅元鑄造大省，光緒二十九年（1903）至民國六年（1917）十二月，成都和重慶兩個官方廠所鑄銅元數量位居全國之冠。
In the twenty-sixth year of Guangxu (1900), Li Hongzhang played the role of casting copper coins in Guangdong. The Qing copper coins are mainly divided into two categories, the first one is "Guangxu Yuanbao", and the second one is "Daqing Copper Coin". Besides Guangdong, there are more than 20 factories in Fujian, Hubei, Sichuan and Qingjiang. Sichuan is a big copper coin casting province. From the 29th year of Guangxu (1903) to December of the 6th year of the Republic of China (1917), the number of copper coins cast by two official factories in Chengdu and Chongqing ranked the highest in China.
