雍正十三年(1735年)，清高宗即位，改元乾隆。铸行"乾隆通宝"，要求仍重一钱二分，该钱书法铸工都比雍正时更为精美。最初清政府仍继续执行通货紧缩的政策。钱局较雍正时有所增减，首先在乾隆四年，停了宝河、宝巩、宝济三局，于乾隆五年时开宝福局，七年开宝桂局，十年开宝直局。乾隆朝以前的制钱不加锡，以铜、铅、锌配制，称之为"黄钱"，在乾隆五年规定在铸钱铜料之中加百分之二的锡，称为"青钱"。官方说是为杜绝私钱，实则无异于减重。"乾隆四十年时，私铸情况日盛，各省官员出现盗铸，政府对此无计可施，加上云南铜产量逐年递减，导致铜价飞涨，铸钱成本也随之水涨船高。清政府继而又采取了通货紧缩政策，先后停铸了宝直、大理、广西、临安等局，同时鼓励商人从海外进口铜材。但是这些措施未能从根本上解决问题，私铸虽有所减少，但官钱不见增加，民间交易缺钱，就出现了使用古钱的现象。到了乾隆五十年后，又相继开了宝直等局，同时放宽了铸钱的标准，所以导致乾隆后期制钱的质量参差不齐，大不如初的情况。此外在乾隆朝时期在新疆出了"乾隆通宝"红钱(也做普尔钱，"普尔"维语即钱的意思)，是以新疆产铜为原料，在新疆地区铸行的，此后各朝均有铸行。

First of all, in the fourth year of Qianlong, Baohe, Baogong and Baoji were stopped, the Baofu Bureau in the fifth year of Qianlong, the seven years, and the Baoyi Bureau in ten years. Before the Qianlong Dynasty, Emperor Qianlong did not make tin, made with copper, lead and zinc, called "yellow money" . In the fifth year of Qianlong, two percent of the tin should be added to the cast copper materials, which was called "green money" . Officials say that is to eliminate private money is actually tantamount to losing weight. "In the 40 th year of Qianlong, the private casting was booming, and provincial officials appeared stealing casting. The government had no means to do. Moreover, the decreasing copper production in Yunnan year by year, leading to the soaring copper price and the cost of casting money increased. The Qing government then adopted the deflation policy, successively stopped casting Baozhong, Dali, Guangxi, Lin ' an and other bureaus, and encouraging merchants to import copper from overseas.
