Don't know about this banknote and the stamped flag itself at all, but my best guess is that after North Vietnam formed, they stamped these, in this case with the North Vietnamese flag to make it a legal currency there before they could come up with their own currency. Usually banknotes are stamped like this right after a new country is formed (Yugoslavia, Czechoslovakia etc. put stamps on the old Austrian Coronas, Serbia during WW2 overprinted their Yugoslav banknotes and so on.)

hello thank you very much for your answer I also think of the same thing as you, while waiting for more information on this banknote, I have done so much research but found nothing, we are waiting for other answers in any case thank you for your answer!!!
