Old China what date ? [opgelost]

An old China coin any help to tell what is the date . Thank you

Hello, I am a friend from China and I am Chinese. This coin was made in China in 1736, during the reign of Emperor Qianlong of Qing Dynasty, during which Emperor Qianlong's Tongbao was the circulating currency. During his 60-year reign, Emperor Qianlong practiced his strategy of "governing culture and martial arts" and created the last glorious age in feudal society. After that, it was widely believed that wearing "Qianlong Tongbao" copper coins could ward off disasters and evil spirits, and it was favored by collectors of later generations because the word Qianlong sounded like "Qianlong".
The coin was cast during the reign of Emperor Gaozong and Emperor Qianlong (1736-1795) in the Qing Dynasty. The Manchu script on the back is complex, with detailed price and coin rubbings on it. Qianlong Tongbao money diameter about 25 mm, weight about 3g. Money face text "Qianlong Tongbao" written in regular script, its words from the top down and right and left straight reading. Money back text along Yongzheng Manchu money type perforation on the left side of the word "treasure", perforation on the right cast the name of each bureau [1]. Currencies also vary in shape and size from time to time！
