Since these un-overprinted stamps were never used there is no genuine postal history. Sometimes one can see letters that were favor cancelled after the end of the war or NLF stamps mixed in with North Vietnamese stamps also used after the war but they are basically philatelic documents that were simply made up to please collectors. NLF stamps were not permitted to be used in the North (mostly because the currency units were simply not compatible) so the mixed frankings one sees once in a while simply slipped through unrecognized or were obtained by bring the postal clerk.
Immediately after the “Fall of Saigon” on April 30th, 1975 there was a shortage of properly denominated stamps to cover the standard domestic letter rate which was 25D at that time and increased to 30D in June of 1975. The first 30D stamp with the inscription “Cong Hoa Mien Nam Viet Nam” were released on May 19th, 1975 (Michel Nr. NLF 54a) and even then these stamps were very slow in being distributed, especially to the central parts of Vietnam. As a result locally old NLF stamps denominated in xu (in the NLF currency) and Dong (of the South Vietnamese regime) were overprinted with black crosses or new values in black and red. These overprints were executed by hand, stamp by stamp, so there is great variability as to where the overprint was struck on each stamp and to what degree of pressure.

The editor has yet to see genuine postal history on which these stamps were used prior to the “Fall of Saigon” (April 30th, 1975). Ta Phi Long shows one cover with a 10D on Michel Nr. NLF 29 presumably used on May 13th, 1974 in Cam-Lo but the cancel on the stamp does not show the city name or date and does not touch the cover so this letter may have been doctored with. Also the bottom of the Cam-Lo cancel that is struck on the envelope itself is not visible so this may simply represent a cancel from the old South Vietnamese Regime without the proper “M.N.” addition that fell into the wrong hands. Finally the 10D rate was incorrect in May of 1974; it should have been 25D something a forger may not have been familiar with. There are genuine covers after April 30th, 1975 but they all look like philatelic covers made to please philatelist.
Forged overprints abound. Here are three stamps with a counterfeit 15D overprint.
