The diameter of small coins in Kangxi and Yongzheng is relatively large. Most coins in circulation are between 2.6 and 2.7 centimeters in diameter. Those below 2.5 cm are called samples, and those above 2.8 cm are called samples. The small flat money after Daoguang is very small, and the diameter of 2.4 cm is not a sample. If it reaches or exceeds 2.5 cm, it is a "large sample".
For example, Qin Banliang has different sizes, and it is not easy to find a sample size. Generally, the terms "large sample" and "small sample" are not used, so "large sample" and "small sample" are similar to the concept of relative size of coins, but they are not applicable everywhere. The number of large samples and small samples is relatively small, but it is not small. It can be used as a collection of editions and varieties to increase the interest of coin collection.
In a broad sense, it refers to money with a diameter of more than 1mm, and in a narrow sense, it refers to the large-scale production of money with a diameter of more than 26.5cm, which is called wanxuan money by Japanese magazines or palace money by some people, which is different from Fang Tong's details and Xiaoping's details.

Casting background:
In the 13th year of Yongzheng (1735), Emperor Gaozong ascended the throne in the Qing Dynasty and changed to Qianlong. Casting "Gan Long Bao Tong" still needs a minute and twenty cents, and the foundry workers in Shufa Qian are more particular than those in Yongzheng.
Money before the Qianlong dynasty was made of copper, lead and zinc, and it did not contain tin, so it was called "yellow money". In Qianlong five years, it was stipulated that 2% tin should be added to the copper material for casting money, which was called "green money". "Forty years after Qianlong, private casting flourished, and provincial officials stole it. There is nothing the government can do about it. In addition, the copper production in Yunnan is decreasing year by year, which leads to the soaring copper price and the rising cost of casting money.
The Qing government then adopted a deflationary policy, stopped casting Baozhi, Dali, Guangxi and Lin 'an bureaus, and encouraged businessmen to import copper from overseas. However, these measures failed to fundamentally solve the problem. Although folk casting decreased, official money did not increase, and folk transactions were short of money, so the phenomenon of using ancient money appeared.
Fifty years after Qianlong, Baozhi and other bureaus were opened one after another, and the standard of casting money was relaxed, which led to uneven quality of making money in the later period of Qianlong, which was much worse than that at the beginning. In addition, during the Qianlong period, the "Qianlong Bao Tong" red money (also known as Pur money, which means money in Uighur) was produced and cast in Xinjiang. Since then, it has been cast in various dynasties.
Historical value:
Emperor Qianlong, Emperor Gaozong of the Qing Dynasty, ascended the throne in 1735. During his 60 years in office, he used the strategy of "ruling the country by civil and military means" to create the last moderns in feudal society. Later, it was widely rumored that wearing the "Qianlong Bao Tong" copper coin could ward off evil spirits, and it was loved by later collectors because it was homophonic with Qianlong.
Gan Long Bao Tong was released for a long time and had a huge cast. Coupled with the short circulation time, most of them are of low value. The carved mother and mother money of Qianlong are rarely circulated, so they are now very popular with collectors and have high collection value.
