Mint block of four that shows a number of re-occuring plate errors. The top left stamp (Field 5) shows the plate errors of “two dots under the E of VIETNAM” and “a black dot on the left side of the green frame”. The black inscription also shows a double impression caused by a insufficiently tightened rubber mat causing vibrations. The bottom left stamp (Field 15) shows the plate errors of “black dot under B of BUU”, “two dots under E of VIETNAM” and “a green dot on top of ET inside the medallion”. The top right stamp (Field 6) shows the plate error of “an additional black dot after the inscription on the right side.” The stamp also shows a double impression of the black color.

Detailed scans of the affected areas:
These stamps were not officially issued im-perforated but a small number of im-perforated trial proof have come to market. Below are the phase prints of the 30 xu value. The first one shows only the blue color while the second one shows the blue and red color.
The im-perforated proofs of the finished stamp come also in two paper varieties. The first one is printed on white paper while the second one is printed on grayish paper. Also note the much clearer impression of the first stamp.
Phase prints of the 1 Dong value. The first one is executed in the green color only, the second one shows the 1 Dong proof in the blue color of the 30 xu stamp (!) and the third proof shows both the green and red color.
Exceedingly rare trial proof (ex Klewitz) that shows the 1 Dong finished stamp in a light green color. This color proposal was finally rejected as evidenced by the issued stamps. It is also interesting to note that the proof already shows the same plate error of two dots under E of VIETNAM.
