法屬印度支那貿易銀圓，俗稱坐洋，為清末在華流通的外國銀圓之一。銀元正面希臘自由女神坐像，這也是“坐洋”得名的原因。坐洋的前身為法國政府在交趾支那（南部越南政權）于1879年 。開始鑄造10仙、20仙、50仙、1皮（法制單位元）的交趾支那銀幣。時至1885年，法屬安南政府為抵制墨西哥銀幣及美國貿易銀幣，于1885年開始鑄造一元銀幣。

面值1元的坐洋的版式可以歸納為三種：重量、年號和記號的不同。坐洋銀元是從1885年開始鑄造的，一直到1928年停止鑄造，但是其中有紀念並沒有鑄造，它們的的年份分別是1892年、1911年、1912年、1914年到1920年、1923年，因此，坐洋銀元實際上只鑄造了32年。在這32年當中，其中，1885年到1895年和1905年這11個年份所鑄造的坐洋的重量都是27.215克，這些坐洋的重量比其他年份的坐洋略重一些，人們都稱之為加重版。
The face value of $1 can be divided into three types: weight, number and mark. The silver dollar was first minted in 1885 and was not minted until 1928. However, the commemorative COINS were not minted. They were dated 1892, 1911, 1912, 1914, 1920 and 1923 respectively. Among these 32 years, the 11 years from 1885 to 1895 and 1905 weighed 27.215 grams. These years were slightly heavier than the others, and they were called weighted versions.
