There are 4 printings
of the 4 cents.
(Sep 1873) - ultramarine/brown. Perforated 14 x 13 1/2. Inv. frames pos. 18 and 77. There is only one known cover with a bisected 4 cents of Printing 1.
(May 1878) - light blue/yellow brown. Perforated 14 x 13 1/2. Printing 2 is not as common as printings 3 and 4. There are no inverted frames in Printing 2.
The stamps from printing two have a greater
catalog value. Printing two stamps are likely stamps the collector had stashed away and put into use to perhaps generate another philatelic variety.
One person, a Mr. A. Duurloo - produced a number of small covers (95 x 54 mm- see photo
below) with stamps from printing 2 that were all canceled St.Thomas May 6.
Stamps from Printing 2 are more often used on covers mailed from Christiansted and Frederiksted as compared to St. Thomas.
(Mar 1901) - dull greenish slate blue/light yellow brown - one inverted frame in position 51. Perforated 12 3/4. Color variation appears which makes it difficult to identify Printing 3 from Printing 4.
(Jun 1902) - clear light blue/yellow brown - 11 inverted frames in position 51 and 91-100. Perforated 12 3/4. Color variation appears which makes it difficult to identify Printing 4 from Printing 3.
Printing 4 is the most commonly used
bisected 4 cents stamp.
It is not known how many stamps were biseced and used. Estimates have ranged from as few as 2.500 to as many as 53.000 - but there could easily have been more than 10.000 letters.
