Gold coin, whose foreign language meaning is equivalent to gold coin, refers to the ancient currency made of precious gold. In the currency history of China, gold and silver were officially called "gold ingots", which began in the Yuan Dynasty.
But as early as the early Tang Dynasty, when Kaiyuan Bao Tong was alive, the people read it as "opening an ingot" because of its huge and precious value. In the Yuan Dynasty, gold, silver and money were called "ingots", which means the treasures of the Yuan Dynasty.
In the currency history of China, gold and silver were officially called "gold ingots", which began in the Yuan Dynasty. However, as early as the early Tang Dynasty, in the Kaiyuan Bao Tong period, people regarded it as huge and valuable, and read it as "opening an ingot". In the Yuan Dynasty, gold and silver coins were called "gold ingots", which means the treasures of the Yuan Dynasty. Gold is called gold ingot and silver is called silver ingot, which is not only of political significance, but also the common name of gold and silver currency.
In the 13th year of Yuan Dynasty (1276), after the Yuan army destroyed the Southern Song Dynasty, it returned to Yangzhou. Bo Yan, the Prime Minister, ordered the luggage of the troops to be searched, and the money collected was cast into ingots and presented to North Korea. The money seller in charge of this matter made a silver ingot weighing 520 taels according to the example of the silver collar in the Jin Dynasty, and named it "Yangzhou Yuanbao", which was dedicated to the ancestor Kublai Khan.

At that time, the ingot was saddle-shaped, with arcs at both ends and a waist in the middle, which was very similar to the silver collar in the Southern Song Dynasty and the Jin Dynasty. "Yangzhou Yuanbao" was unearthed later, generally about 14.5 cm long and 3 cm thick. The back is engraved with the Chinese character "Yuanbao".
In the monetary history of China, the discovery and use of silver was later than that of gold. Experts believe that this is because silver ore is often combined with copper and lead, and smelting decomposition technology is difficult to master. Therefore, it was after Emperor Wu of the Han Dynasty that silver was used as a monetary material, and casting into various shapes as a weighing currency for payment began in the Tang and Song Dynasties.
