Color Trials; prior to authorizing the final printing run for stamps the Vietnamese Postal Authority requested a few sheets of color sheets on one particular value of a set in order to decide which final color combination would be best suited for each stamp within the set. The color sheets had the size of a standard sheet but contained alternating color options on the designated nominal value. While these sheets were only intended for internal postal use some of them came to market. Virtually all of these complete sheets were cut apart. So one mostly finds single color proofs or small strips of them. While they are actually very rare one can still obtain them for under $10 a piece (with some exceptions) as not many collectors appear to have an interest in them so far. Here are various color trials for the 0.50D value. Note that the blue tone is different from the finally issued stamp.

Normally color trials were only produced in one nominal but there appears to be an exception with this set as color trials of the 2D value have appeared. These are substantially more rare than the trials for the 0.50D value. The 2D orange value shows a slightly darker orange than the finally issued stamp.

Part of the production process for stamps included the production of a small number of sunken die proofs. These were used to ensure the final appearance of a stamp met the expectations of the postal administration. These are generally rare. Here are two different versions of the 50c value in vivid brown-red and dark-brown-red (according to the Michel Color Guide). Both are signed by the stamp’s designer.
