乾隆通宝，就是由于清高宗乾隆皇帝于公元1735年即位，在位的60年里施展其"文治武功"的治国策略，创造了封建社会里最后一个辉煌盛世，之后民间便盛传佩带"乾隆通宝"铜钱可驱灾辟邪，又因乾隆二字谐音"钱隆"而备受后世藏家所喜爱的钱币。 乾隆通宝连宝泉、宝源在内先后有29局开铸，多用黄铜与青铜，也引进国外洋铜浇制法。新疆地区新用方孔圆钱，开设伊犁、阿克苏、乌什、叶尔羌、喀什葛尔、库车等局，因用自产红铜鼓铸、故称为"新疆红钱"或"普尔钱"("普尔"维语即钱的意思)。乾隆通宝只少数钱背文看见星号或汉字。乾隆通宝还有合面钱、吉语钱以及私铸劣质钱、鹅眼钱等，品类不下百种，存于世上的有雕母数种，至为珍贵。 由于钱币在历代就具有很高的收藏价值，故在各个历史时期均有仿冒钱币出现，如何鉴定其真伪难度较大。鉴定真伪一定要从钱币的形状、质地、包浆、文字和制作工艺等诸多方面来识别。每一时期的钱币，形状、质地和文字都有其独特的风格和特征。各个历史时期的铸造工艺不尽相同，仿冒者不可能完全把握。钱币的价值如何，要看钱币的年代和存世的数量多寡来确定。钱币不仅有经济价值，更有历史价值和艺术价值，而历史价值和艺术价值又直接影响着经济价值。

Qianlong TongBao, is due to the qing dynasty the emperor qianlong emperor acceded to the throne in 1735 AD, in the 60 years of its "tai temple" governing strategy, create the brilliant outstanding achievement in the feudal society in the last millennium, after folk rumours that wear "qianlong TongBao" copper can drive off evil, and because of the word "qianlong homophonic" Qian Long "by later generations collectors favorite COINS. In The Qianlong Period, there were 29 bureaus including Tongbao, Baoquan and Baoyuan, which used brass and bronze, and also introduced foreign copper casting method. In Xinjiang, square hole round money was newly used, and bureaux in Yili, Aksu, Wushi, Yarqiang, Kashgar and Kuqa were opened. The bureaux were called "Xinjiang Red money" or "Pulqian "(" Pulqian" means money in Uyghur) because of the use of self-produced red drums. Qianlong Tongbao only saw asterisks or Chinese characters on his back. Qianlong Tongbao also has more than 100 kinds of dough money, auspicious language money, private cast inferior money, goose eye money, etc. There are several kinds of diaomu in the world, which are most precious. Because coins have a high collection value in all dynasties, counterfeit coins appear in all historical periods, and it is difficult to identify their authenticity. Authenticity must be identified from the shape, texture, coating, text and production process of the coin. The shape, texture and characters of coins in each period have their own unique style and characteristics. The casting process in different historical periods is not the same, and imitators can not completely grasp. The value of money depends on the age and number of coins. Coins not only have economic value, but also have historical value and artistic value, which directly affect economic value.
