开元通宝，唐高祖武德四年（公元621年）铸币。据《旧唐书·食货志上》载：“武德四年七月，废五铢钱，行开元通宝钱。开元通宝之钱文，为给事中欧阳询制词及书。”
Kaiyuan Tongbao, Tang Gaozu Wude four years (AD 621) coinage. According to the book of Old Tang Dynasty, Food and Goods Chronicle, Wude spent five baht money in July of four years, and Kaiyuan Tongbao coin was used. Qian Wen, Kaiyuan Tongbao, made words and books for Ouyang inquiry.
同时，开元通宝是唐朝统治286年中的主要流通货币，并且影响了中国一千多年铸钱的形制、钱文模式和十进位衡法。其“开元”二字内涵丰富，意义深远。
At the same time, Kaiyuan Tongbao was the main currency in circulation during the 286 years of Tang Dynasty's rule, and influenced the form of money-making, the mode of money-writing and the decimal balance law in China for more than a thousand years. The word "Kaiyuan" has rich connotation and far-reaching significance.
唐代所铸的开元通宝金银钱，与之前之后的朝代一样，主要是用于宫廷赏赐或玩赏的礼钱性质。如唐《开元天宝遣事》说，“内廷嫔妃每至春时，各于禁中结伴三人至五人，掷金钱为戏”。此外，唐玄宗观看杨贵妃给安禄山 “洗三”时，也就是安禄山生日的第三天，杨贵妃用锦缎象包裹新生儿一样把安禄山包裹起来，用轿子抬着，众人感到新奇，大声喧闹。玄宗看着高兴，就赐给杨贵妃洗儿钱。金银开元钱此外也还用作祭礼等，可起支付的作用，然非流通币。
The Kaiyuan Tongbao gold and silver coins cast in the Tang Dynasty, like the previous and later dynasties, were mainly used for the gift nature of the court reward or reward. As the Tang Dynasty's Kaiyuan Tianbao Reception says, "When the concubines of the court arrive in spring, they are separated from three to five people in the forbidden period, throwing money as a play." In addition, when Empress Xuanzong of Tang Dynasty watched Princess Yang's "wash three" to Mount Anlu, that is, the third day of her birthday, Princess Yang wrapped Mount Anlu with brocade like wrapping a newborn, and carried it in a sedan chair. People felt strange and noisy. Xuanzong looked happy and gave Yang Guifei money laundering. In addition, gold and silver Kaiyuan coins are also used as sacrificial rituals and so on, which can play a paying role, but not negotiable coins.
