The second overprint issue stayed in circulation for over 18 months before the postal authorities issued a third overprint version that was designed to be even more legible than the first and second one. It showed a larger “10d” and “20d” in rectangular boxes. This time the authorities apparently issued instructions to execute these overprints in black only as the few red versions that appear are all very rare and hence probably represent errors. Why these overprints were done in May of 1956 is not known as these overprinted stamps had no more postal application than the second overprint. The standard domestic letter rate as of May 1, 1953 was already 100 New Dong (80 New Dong for post cards) so it is very likely that these stamps were simply used as additions to compensate for unusual weight levels. Catalogues are still pretty deficient in listing all existing stamps.
This is a yet unlisted item. It is the 100 Dong in brown but imperforated
Michel Nr. 39bI and 39bII (Imperforated 100 Dong lilac-brown)
Here are additional unlisted varieties that probably represent overprint errors. The base stamp is the 100 Dong brown perforated but this time with a red overprint (I and II)
At least one of these stamps in brown with the red overprint also exists imperforated (very rare):
Here is a mint block of four of Michel Nr. 41aI:
These are two varieties that are yet unlisted in Michel. It is the 200 Dong brick-red colored stamp with a red overprint. Since it made little sense to use a red overprint on a stamp with a red base color these stamps probably represent errors.
Below is a rare double overprint of 10D on 100D green in red.
Beware of fake overprints that often try to mimic errors such as double overprints or upside down overprints. Here are a few examples of forged overprints. They are typically larger than the originals. Below is a forged 10D on 100 Dong green. Notice the different shape of the “d” and the larger box of the overprint.
Here is a counterfeit 10D on 100 Dong green overprint. Notice the larger numbers and larger box of the overprint . Also the red color has not oxidized and soaked into the stamp as on the originals.
Below is another nonsensical forged overprint of 20D on 100 Dong green. Again, the numbers and the box are larger and the overprint color is not properly aged.
Since the stamps had little postal application used examples virtually do not exist. in over 25 years of Vietnam collecting activity the author has “amassed” a mere two stamps! They were contained in old collections purchased from Eastern Europe. Michel either lists used samples with -.- (cannot be priced due to lack of market activity) or the same as mint stamps. Clearly that makes no sense. All used stamps should be valued with -.- as there are simply no stamps off cover that are offered in the market place. Letters with these stamps do exist but they are very rare. They are often traded from one collector to another, so never see the open market but once in a while a sample is offered by large auction house. Expect to pay between $750-1,000 for a genuine letter bearing just one of these stamps.
Below is a local letter that was most likely philatelically inspired. It features one 10D on 100 Dong brown overprinted on the left (Michel Nr. 39 IaI). The adhesives added up to a total postage of 110 Dong which was 10 Dong over the required postage at that time.
Here is a very rare early letter to the former East Germany. It was sent by an East German staying in Hotel Lam Son in Hanoi to a relative. The postage is a mixed franking of various early NVN stamps among them the rare 20D on 200 Dong carmine (Michel Nr. 41bI-yet unlisted). The overall postage was 580 Dong which was above the 200 Dong surface rate plus the 270 Dong air mail surcharge for letters to East Germany from that period. So, it must have been heavier than what the base tariff allowed for.
Below is a letter from October 1956 to Czechoslovakia. It is franked with a mixed franking of various early NVN stamps among them a pair of 20D on 200 Dong brick red (Michel Nr. 41aI). Overall franking amounted to 590 Dong. The base letter rate at the time to Czechoslovakia amounted to 20 Dong plus a surcharge of 260 Dong for air mail delivery for a total of 470 Dong. So, again, this letter must have been heavier than what the base rate allowed for.
Spectacular franking of all three overprint values (Michel Nr. 39bI, 40aI and 41aI) on a registered letter to West Germany. One, of only two letters known to exist carrying all three values at the same time. This cover dated January 27th, 1957 is one of the earliest letters from North Vietnam to West Germany and carries a total of 1,540 Dong in postage (ex Klewitz). The base letter rate to East Germany amounted to 300 New Dong, the air mail surcharge for a 20 gram letter was 270 New Dong and the fee for registration was 600 New Dong. This letter probably contained a stamp shipment that Theo Klewitz obtained from his local contact in Hanoi, so it is impossible to guess its weight. Klewitz was a frugal fellow so there is no reason to believe that this letter was over-franked. Clearly postally used and unique 3 color combination of this very rare issue.
