袁大头三角圆的制造是1948年11月辽沈战役结束后,为稳定东北解放区金融形势,支援全国解放战争。东北银行总行决定由沈阳造币厂恢复铸造一定数量的袁大头银币。为了让解放区铸造的袁大头与前版加以区别,沈阳造币厂的技术人员首先对民国三年袁像银币原模进行修饰,使肩章和领口处经过修饰后更加清晰大方,同时让“圆”字中贝上面的笔画封口连笔为△型,即三角圆银币。1949年3月,首批三角圆银币铸造完成。1951年,沈阳造币厂遵照中国人民银行指示,为稳定和发展部分边远地区及少数民族地区的金融形势,沈阳造币厂又奉命铸造了两批袁大头银币,即为袁大头O版和O版三角圆。所谓O版,就是在嘉禾花结内隐有“。”暗记,但有的O版不是三角圆。所谓O版三角圆,就是两种特征兼具。目前,这两种银币因数量和存世不多,物以稀为贵,一直受到银币爱好者的重视,价值也在不断提升，值得收藏。如有意向的朋友欢迎咨询。
After the Liaoshen Campaign in Novembern order to stabilize the financial situation in Northeast Liberated Areas and support the national liberation war. The head office of the Northeast Bank decided to restore a certain amount of Yuan Datou silver coins minted by the Shenyang Mint. In order to distinguish Yuan Datou cast in the liberated areas from the previous edition, the technicians of Shenyang Mint first modified the original model of Yuan Xiang silver coin in the three years of the Republic of China to make the shoulder and collar more clear and generous after the modification. At the same time, the seal of the strokes on the shells of the word "circle" was made into a delta shape, i.e. a triangular silver coin. In March 1949, the first trigonometric silver coins were minted. In 1951, the Shenyang Mint followed the instructions of the People's Bank of China. In order to stabilize and develop the financial situation in some remote areas and minority areas, the Shenyang Mint was ordered to coin two batches of Yuan Datou silver coins, i.e. Yuan Datou O-version and O-version triangles. The so-called "O" version implies "Jiahe flower knot". Keep in mind, but some version O is not a triangle. The so-called O-version triangle circle is the combination of two characteristics. At present, these two kinds of silver coins are valued by the silver coin fans because of their small quantity and existence, and their rarity. Their value is also constantly rising. They are worth collecting. Buyers who need them are welcome to consult.
