坐洋币是法属印度支那贸易银圆，俗称坐洋，为清末民初在华流通的外国银圆之一。银币正面为自由女神坐像，背面的装饰图案为鹰，法文有“贸易银元”和“法属印度支那”等。银元正面希腊自由女神坐像，这也是“坐洋”得名的因素。各种坐洋断断续续发行至1937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，外国银圆在中国的好日子不复再了，恰好的是这个时候坐洋也销声匿迹了。
此枚银币正面为手执束棒的自由女神坐像，背面的装饰图案为麦穗，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“1896”。银币背面的主图案为一花环，周圈为说明文字，花环上方铸法文为“FRANCAISE INDO-CHINE(法兰西印度支那)”。
钱币随着市场从无人问津开始到辉煌的巅峰时期忙，收藏价格和成交价格也不断的刷新不断的飙升。“坐洋币”银元作为一种历史载体，记录了鸦片战争以后，中国人民政治上受压迫，经济上受剥削的屈辱历史。研究在中国流通的外国货币，对于我们了解外国列强利用银元贸易，掠夺中国财富的罪行，增强爱国主义精神，为中华民族的伟大复兴贡献力量，具有十分重要的意义。
