开元通宝是唐朝统治290年中的主要流通货币，在我国钱币史上具有划时代的地位,而且影响了中国1000多年钱币的形制、钱文模式和十进位衡法。唐初沿用隋五铢，轻小淆杂。唐高祖武德四年，为整治混乱的币制，废隋钱，效仿西汉五铢的严格规范，开铸“开元通宝”，取代了社会上遗存的五铢。这种钱巨细适中，制作细腻，币值稳固，黎民乐用，终于徐徐驱逐了一切古钱和私钱，成了天下通用的钱币。
Kaiyuan Tongbao is the main circulating currency in the 290 years of the Tang Dynasty. It has an epoch-making position in the history of China's coins, and affects the shape, money model and decimal equity of China's coins for more than 1,000 years. In the early Tang Dynasty, the Sui five baht, light and miscellaneous. In the fourth years of Emperor Gaozu of the Tang Dynasty, in order to regulate the chaotic currency system, he abandoned the Sui Dynasty, followed the strict norms of the five baht of the Western Han Dynasty, and cast the "Kaiyuan Tongbao" and replaced the five baht remaining in the society. This kind of money is fine, exquisite production, currency value is stable, Li Min happy, finally slowly expelled all the ancient money and private money, became the common coin in the world.
另外，许多人都认为开元通宝是年号钱，理由是唐玄宗李隆基有个年号是开元，这是错误的。开元通宝是非年号钱，在唐代初年就已经铸造，是由欧阳询亲自题字，欧阳询是初唐人物，而李隆基生于盛唐，二人生活年代相差百余年，从年代上讲，欧阳询就不可能给李隆基的铸钱题字。而李隆基将年号定为开元，纯属巧合。
In addition, many people think that Kaiyuan Tongbao is the annual number of money, for the reason that Li Longji, Emperor Xuanzong of the Tang Dynasty, has an annual number that is Kaiyuan, which is wrong. Kaiyuan Tongbao is non-annual money, in the early Tang Dynasty has been cast, is by Ouyang Xun himself, Ouyang Xun is the early Tang character, and Li Longji was born in the Sheng Tang Dynasty, the two people lived more than a hundred years, from the era, Ouyang Xun can not be able to cast money for Li Longji. And Li Longji set the annual number as Kaiyuan, it is a pure coincidence.
此枚开元通宝，背上月纹直径25.10mm，重3.6g.铜钱品相较好，包浆自然。关于开元通宝钱币背面月纹与皇后指甲痕之间有一个传说的故事。自唐朝以来，民间关于开元通宝钱币的传说，除了将钱文读作“开通元宝”之外，最有影响的就是有关开元通宝钱币背面月纹的由来了。
“开元通宝”背面的甲痕这一传说在民间影响很大，金朝李俊民曾经写诗说：“金钗坠后无因见，藏得开元一捻痕”；陈其年也有诗曰：“有似开元钱样，一缕娇痕巧印”。说的就是唐玄宗晚年怀念杨贵妃，睹钱思人的情景。这本来都属于无稽之谈，早在北宋时期司马光就已经考证指出，铸造开元通宝钱时，窦皇后早已去世，文德还没有被册立，杨贵妃甚至尚未出生。但是以讹传讹，民间至今仍然流传有这种传说。
This open yuan tong treasure, back last month grain diameter 25.10mm weight 3.6g. copper money appearance is good, the pulp is natural. There is a legendary story between the moon mark on the back of the coin and the Queen's nail mark.
Since the Tang Dynasty, the folk legend of Kaiyuan coins, in addition to reading Qian Wen as "opening ingot", the most influential is the origin of the moon pattern on the back of Kaiyuan coins.The legend of the nail mark on the back of "Kaiyuan Tongbao" has a great influence in the people. The Jin Dynasty Li Junmin once wrote poetry and said: "Jin Chai after falling, hidden a Kaiyuan twist mark"; Chen Qisheng also has a poem: "there is like Kaiyuan money, a wisp of delicate marks". It is said that Emperor Xuanzong missed Yang Guifei in his later years and saw the scene of Qian Sisi. This was originally nonsense. As early as the Northern Song Dynasty, Sima Guang pointed out that when the Kaiyuan Tongbao money was cast, Empress Dou had already died, Wende had not been registered, and Yang Guifei had not even been born. But wrongly spread, there is still this legend spread among the people.
