It is made of alloy, 45mm across, and engraved with the images of the statue commemorating the victory and the bunker of French General De Castries.
Le Tran Truong An, general director of Vietbooks, said: "The coin is aimed at acquainting tourists with the remarkable Dien Bien Phu victory.
"I and my staff are working to present a collection of four coins showcasing famous historical sites in HCM City to mark the 39th anniversary of the liberation of the South."
They will carry images of Notre Dame Cathedral, the HCM City Museum, Reunification Palace, HCM City Museum, Opera House, and Ben Thanh and Binh Tay markets.
They are expected to be unveiled at the HCM City Book Fair next week.
Since 2013 Vietbooks has released 56 coins, with the bestsellers being those with the images of Con Dao, where the French colonists jailed political prisoners, and Vo Thi Sau, the heroine who was executed by the French.
