A barrel of French coins issued in 1942 was found Wednesday in Nghe An Province.
Construction workers found the 100-kilogram barrel one meter underground. Most of the coins are still intact. They have been transferred to Nghe An Museum.
The lettering on the coins reads "ETAT Francais" and "Indochine 1942".
Truong Dac Thanh, deputy director of the museum, said the coins were issued by the Banque de l'Indochine (Bank of Indochine), established in Paris in January 1875, for French territories in Asia.
From 1889 to 1900, the bank shifted its operations from Indochina to China and in 1942 opened a branch in Japan.
The barrel was found at the site of a former trading area, now located in Vinh, the coastal capital of Nghe An Province.
