This is the "7th Anniversary of the Founding of the Party" circulating commemorative coin issued in 1991. There are 3 commemorative coins in full set, all of which are denominated in 1 yuan. The front designs are: a former site, Zunyi Conference and the Third Plenary Session of the Eleventh Central Committee. The coin is made of copper-nickel alloy. The circulation of this coin is 3 million sets, which is a large variety of commemorative coins in circulation in the early and middle period. It is very common in the coin market and has little appreciation potential. At present, the retail price of each set of commemorative coins is about 25 yuan. Your only item is the Zunyi Meeting, which is not complete, and its value is around 7 yuan. I hope I can help you. . .
