Letter mailed in July of 1967 featuring a mixed franking of the 50xu Geneva Convention stamp plus the 2xu Mountain Province issue for an overall postage of 52xu. The standard letter rate was only 12xu so either this letter must have beeb much heavier than normal or it was franked incorrectly using the required postage to Western countries.

Rare registered letter mailed by Xunhasaba containing a stamp shipment to a client in Munich, West Germany. It was franked with four of the 50xu Geneva Convention stamps and a mix of other NVN stamps for an overall postage of 2.32D. The standard letter rate to West Germany (up to 20g) amounted to 50xu and the registration fee to 60xu. So the contents of this letter must have exceeded the standard 20g weight level.
Here is a letter with the 12 xu and 50 xu value sent to Klewitz in August of 1965. The overall franking amounted to 1.60 Dong which was well in excess of the required postage of 50 xu for a standard letter to Western Europe.
Letter from a Vietnamese exchange student that sent New Years Greetings to his former host family. The content is still in the letter consisting on a greeting card that shows flowers, landscape but also a plane being shot down. Since the letter was heavier than the standard 20 grams the postage that was used was 62 xu (standard postage was 50 xu).

Rare single franking of the high 4 Dong value in the set sent from Gregor Schwirtz to Theo Klewitz in West Germany in 1979. Schwirtz was a linguist that spoke Vietnamese and that collaborated with Klewitz on many philatelic issues. Since the standard rate of a letter was only 50 xu this letter is most likely over-franked in order to document the value on postally used cover. Still, the 4 Dong is still very hard to find on cover.
Another rare single franking of the 12 xu on a letter to Hungary.
