North Vietnam, Liberation of the capital of Hanoi, January 1st, 1955 (Michel Nr. 23-25); the Viet Minh did not waste much time after taking over Hanoi in October 1954 and they issued a new stamp set to commemorate the event. The stamp showed a soldier with two children in front of the “Pagoda of the lost sword” a symbol of the city. The nominals covered the same spectrum as the Victory at Dien Bien Phu which indicates that the domestic standard letter rate was still 100D at the beginning of 1955. All three nominals were printed of the same plate with just the value exchanged after each printing. The sheet size was 36 stamps (six rows of six stamps).
Postally used set, hard to find:
Here is a piece cut from a letter featuring one of the 50D values postally used.
Beware of cancelled to order (CTO) sets as they are worth only a fraction of the used catalogue value. They have the typical “Hanoi” corner cancel over four stamps.
While the production process at the Vietnam National Printing Works was a lot more professional than at Viet Bac there are a number of plate and perforation errors.
There is a plate error that occurs on all nominals in field A3. This is caused by the fact that the same base plate was used for all three values. Only the nominal value was changed in each printing process. This error is commonly called “Clouds in the Lake”. Take a look at the space just below the background tower and you will see cloud like shapes in the lake. Here is each nominal with the error.
Below are two complete sheets of the 10D and 150D value. Notice the “Cloud in the Lake” plate errors on each Field A3 (third stamp from the left in top row).
Sometimes crafty sellers will pass up a simulacrum (or color kiss) on the back of these stamps as an error. The effect is often called “permeability” which of course is pure nonsense. No color permeated here. The image is caused by putting complete sheets where the color was still moist on top of each other resulting in a mirror image of the stamp in more or less completeness on the back. Do not be fooled. This effect was quite common on this issue and does not justify any price increases. Actual printing on the backside of stamps has to be identical in image and not a mirror image of the stamp to be genuine.
Along a similar line is grade of color adjustment and wear of the printing plate. Sometimes sellers will try to pass a poor print of a stamp as an error. Take a look at the two 10D value side by side. The left stamp was printed when the plate was still fairly new and hence offers much greater detail. The right stamp must have been printed with either with a lower degree of color adjustment or when the plate was already worn. The poor quality stamp does not justify any price increases.
Below are some perforation errors. They do occur but are pretty rare.
Below is a rather curious error. This block of four shows a mixed perforation. The perforation in the middle of the block is nowhere near the 11.5 of the rest of the block. This probably happened when the sheet was delivered to the post office imperforated in-between and locally a different sized perforation iron was applied to the row to provide it with some sort of perforation. Very rare post master perforation.
Postally used covers surviving from the era are still rare and consist almost exclusively of international mail to fellow communist countries. Here is a mixed franking paying the postcard rate of 180D to Czechoslovakia (October, 1956) that shows one copy of the 10D value. The 10D value is rather hard to find on cover as it was an extension value and basically could only be sensibly used in this combined fashion:
Below is a postcard to Czechoslovakia paying the 550D rate that was in force at the end of 1957 bearing one specimen of the 50D value. Again, this was this nominal’s function and so it mostly appears in mixed frankings like the one seen here. Note the dramatic postage increase caused by rapid inflation in little more than a year.
Letter mailed in February of 1957 from Hanoi to China bearing a pair of the 100D Dam stamps (Perf. 11.5) and a pair of the 50D Liberation of Hanoi stamps for an overall franking of 300D paying the surface letter rate to that country.
Mixed franking of one 150D value each (Dien Bien Phu and Liberation of Hanoi) paying the surface letter rate to China. Round and square Chinese censor hand stamps on the reverse.
Two similar frankings to China but this time with a pair of the 150D value, again paying the 300D standard surface letter rate to that country. Note the square and round Chinese censor hand stamp plus the interesting Chinese machine arrival stamp on the reverse..
Below is a very rare destination letter to Luxembourg from February, 1955. The letter was sent by the North Vietnamese Philatelist Society to the President of the international stamp exhibition organization and it bears a 910 Dong franking. Though sent to a Western country to where postage was usually higher, this was unlikely the standard letter rate at the time as the envelope probably contained stamp specimen meant for the exhibition and this was heavier than normal.
