法属印度支那贸易币,俗称坐洋币,为清末在华流通的外国货币之一。钱币正面为自由女神坐像，背面的装饰图案为麦穗，法文有“贸易银元”和“法属印度支那”等。钱币正面希腊自由女神坐像，这也是“坐洋”得名的因素。
坐洋币的主币“壹圆”的铸造时间从1885年开始，在巴黎铸造，至1928年共计43年。各种坐洋断断续续发行至1928年,因为战争的阴影而宣告结束。而中国在1933年实行废两改元后,船洋法币逐渐一统市场,外国银圆在中国不受重视,恰巧的是这个时候坐洋也销声匿迹了。
坐洋币作为一种历史载体，记录了鸦片战争以后，中国人民在政治上受压迫，在经济上受剥削的屈辱历史。研究在中国流通的外国货币，对于我们了解和认识这段历史，具有十分重要的意义。
此件藏品名为坐洋币，钱币正面的主图为手执束棒的自由女神坐像，坐像的两侧铸法文文字是：REPUBLIQUE FRANCAISE（法兰西共和国）。女神座下方有小字法文BARRE和该币发行的年份。
钱币背面的主图案为一花环，周围为说明文字，花环上方铸法文为：FRANCAISE INDO-CHINE（法兰西印度支那），钱币花环中间的横向文字为银币的面额：PIASTRE DE COMMERCE(皮阿斯特的贸易银)。钱币花环下方文字为：TITRE 0.900 POIDS 27 GR。正下方中间位置的双火炬中的小字“A”则可视为版别。正面与背面有360度的错位。
The French Indian ** trade currency, commonly known as the sitting foreign currency, was one of the foreign currencies circulating in China at the end of the Qing Dynasty. The obverse of the coin is a seated statue of the Statue of Liberty, and the reverse is decorated with ears of wheat. In French, there are "trade silver dollars" and "French Indian **". The Greek statue of the Statue of Liberty sitting on the obverse of the coin is also a factor in the name "sitting in the ocean".
The main coin of the sitting foreign currency, the one yuan, was minted in Paris from 1885 and lasted for a total of 43 years until 1928. All kinds of foreign currency were intermittently issued until 1928, when it came to an end due to the shadow of war. After China implemented the policy of abolishing the dual currency system and changing the yuan system in 1933, the market for foreign silver coins gradually became unified, and foreign silver dollars were not valued in China. Coincidentally, at this time, the foreign currency market disappeared.
As a historical carrier, sitting on foreign currency records the humiliating history of the Chinese people's political oppression and economic exploitation after the Opium War. Studying the foreign currencies circulating in China is of great significance for us to understand and comprehend this period of history.
This collection is called sitting foreign coins, and the main image on the obverse of the coin is a statue of the Statue of Liberty holding a rod. The French characters on both sides of the statue are: REPUBLIQUE FRANCAISE (French Republic). Below the constellation of goddesses is the small French word BARRE and the year of issue of the coin.
The main pattern on the back of the coin is a wreath surrounded by explanatory words. The French inscription on the wreath is FRANCAISE INDO-CHINE, and the horizontal character in the middle of the wreath is the denomination of the silver coin: PIASTRE DE COMMERCE. The text below the coin wreath reads: TITRE 0.900 POIDS 27 GR. The small letter "A" in the middle position of the double torches directly below can be considered as the edition. There is a 360 degree misalignment between the front and back.
