安南, 虽然中国歷代的周边国家和丝绸之路所经过的文明也深受中国的文化，政治与经济影响，可是安南（越南）是中国以外铸行方孔圆钱时间最长、品类最多、数量最大的国家，从而突显出安南与中国长达两千年的密切关系。安南有些朝代年号袭用了中国，钱文也採用汉文，而且安南歷代统治者基於铜资源较少，对货币的态度是不拒前朝钱，不拒外来钱，凡是方孔圆钱都能在社会上合法流通，所以和中国古钱会出现容易混淆的情况。不过铸造者為了铸造更多铜钱，获利更大，安南钱大多是体轻铜薄的"水漂钱"，质量和品相都与中国古代所铸铜钱无法相比。不良的声誉令藏家却步，加上越南地区近代战乱频仍，多灾多难，古代典籍遭到破坏，史料严重缺失，因此相关的研究依然缺乏，但不影响其歷史和学术意义，更对中国的钱币收藏者有著重要的参考价值。种类繁多，品相不一，未能尽录。。Annam (Vietnam), a mixed lot of Annam cash coins. The cash coins from Annam all take the typical circular exterior and square holed center form of ancient Chinese cash coins. Though many countries and civilisations around the peripheries of China and along the Silk Road were similarly influenced, Annam was definitely the country which had longest history of minting such coins beyond China, thus making evident the intimate relationship between the two regions through trade, conquest and cultural exchange over two millennia. Since some of the Annam emperors also shared the Chinese era names as their Chinese counterparts, many of the coins share the same Chinese characters, and the proximity of the two countries meant that Chinese currencies were also in circulation in Annam (and vice versa) sometimes lead to confusion when identifying the origin of the cash coins. Furthermore, there are not many copper ores in the region, so any cash coin from whichever era and region were deemed appropriate means for payment as long as they are circular with a square hole. In order to gain more profit and meet market demands, the mints had the tendency to mint coins which are thinner and lighter when compared to Chinese ones, hence they earned the nickname "floating coins". The stigma of Annam cash coins and the records destroyed by wars over the past two centuries meant that they are still poorly understood, but are nonetheless significant and serves as an essential reference for many discerning collectors of ancient Chinese cash coins. mixed condition [211, 212]
