甚少差异，唯以“正”字末笔是否出头分为两式。传世以左竖连下横作“﹂”者为众，末笔出头者稀有。1983年湖南麻阳出土正隆元宝大钱数枚，径2.9厘米，重4.5克，肉薄背平，相当北宋折二钱，是为最新发现。史志多载“正隆通宝”，有误。据报建国后黑龙江曾出“正隆通宝”钱一枚，迄今未曾确认。有合背钱,另有安南铸薄小异体钱。

One of the ancient Chinese coins.
Zhenglong Yuanbao was the first money in the forty-second year of the founding of the People's Republic of China, parallel with the Liao and Song Qian which had been used in the past. Zhenglong Yuanbao imitated the Northern Song Dynasty Daguan Ping Qian production, with excellent texture, handsome writing, regular script Qian Wen Rotation, clean edges, and no writing. It is 2.5 cm in diameter and weighs about 3.4 grams. Zhenglong Qian Wen is dignified and unified.
There are very few differences, but there are two ways to divide the end of the word "Zheng" into two types. Left vertically connected crosswise "people" are the most common ones handed down from generation to generation, and the last one is rare. In 1983, Zhenglong Yuanbao unearthed in Mayang, Hunan Province, had several large coins, 2.9 centimeters in diameter, weighing 4.5 grams. Its meat was thin and flat, equivalent to two coins in the Northern Song Dynasty, which was the latest discovery. History records contain many "Zhenglong Tongbao" errors. It is reported that after the founding of the People's Republic of China Heilongjiang has issued a "Zhenglong Tongbao" money, which has not been confirmed so far. There are coins on the back and small allogeneic coins made by Annan.
