1p1E on 1942 plates printed in wrong order
This example shows the background plate printed on top of the foreground plate. It is posted in 1942, and is one of the 1E papers.
Here is the stamp.
These two high resolution details show the inverse order of printing clearly.
5p1L1 small UL scratch plate variety
These two stamps share the diagonal Upper Left corner scratch and outer scratches Lower Left corner. There are small variations in additional flaws between these two stamps.
Another 5p1L1 and 5p1L2 match plate variety
The main characteristic of this plate variety is a break in the outer frame line under the second to last A of CATARATAS. I show here only two of the 5p1L1 specimens. By how commonly I find this plate variety, I am postulating that it is a master plate variety. In addition, other flaws vary from stamp to stamp.
Here is a 5p1L2 specimen with the same lower line break but with different additional flaws.
Notice that the break appears in the same place for one of the 5p1L1 stamps and a 5p1L2 stamp. The 5p1L2 is the remarkable 'long scratch in background' plate variety.
A second 5p1L1 and 5p1L2 match plate variety
Here is the 5p1L1 stamp.
This stamp has a blue dot to the left of the R of REPUBLICA.
Here is a 5p1L2 stamp that is likely the same plate variety. It is possible that the scratch below ARGENTINA either came out after a light acid wash or was introduced during handling of the plate.
A 5p1L1 and 5p1L2 match plate variety
Here is the 5p1L1 stamp.
This stamp has a lower line break to the frame below and between the EN of ARGENTINA.
Here are two 5p1L2 stamps that are likely the same plate variety. It is possible that the scratch over the palm either came out after a light acid wash or was introduced during handling of the plate.
In one of the many remarkable flukes of this series, the printer managed to match exactly the colors of the early printings for this 1951 issue. Almost all other stamps in this series that were printed in 1951 and thereafter have colors that can easily be distinguished from previous printings.
Here are two specimens with their corresponding watermark scans. Notice that the plates are dirty and/or worn out.
Here is a 5p1L1 with dark colors.
Additional 2pNGR plate varieties
Two regular issue stamps.
'Servicio Oficial' stamp.
2pNGR with two blue smudges above the frame
The main feature of this plate variety is the two blue smudges above the frame. There are additional flaws that vary from stamp to stamp, which may mean that this variety is found on one of the master dies used to make the plate. I find this plate variety on cover.
A regular issue single.
Several 'Servicio Oficial' stamps.
2pNGR remarkable plate veriety
This plate variety is composed of several scratches to the design. Here is a cover bearing a stamp with this plate variety.
I use this second specimen to show the flaws.
Break above the 2 of 2 pesos.
Line breaks above the B and last A of REPUBLICA and scratch across the AR of ARGENTINA.
Small protrusion out of the blue center, blue dot in outer frame, and red dot in inner frame.
A scratch over the F of FRUTICULTURA and two long scratches in the blue design above the I and the L of FRUTICULTURA
Small gap in the blue dots Upper Right.
2pNGR plate varieties with three visible blue corners
This cover bears a 2pNGR with three visible blue corners.
Here is a detail of the 2pNGR and the 30cNGR.
Here is a detail of the 2pNGR.
There are Lower and Upper Left corners similar to some of the stamps with two visible blue corners, and a third corner Upper Right.
The 30c on this cover also has some plate wear to the bottom letters and the value box.
2pNGR plate varieties with two visible blue corners
The first three are regular issue stamps. These first two have Lower and Upper Left corners.
This specimen has Lower Left and Upper Right corners.
And here is a 'Servicio Oficial' stamp with Lower Left and Right corners.
2pNGR plate varieties with one visible blue corner
All in my current sample are 'Servicio Oficial' stamps. The first stamp has the blue outer mark Lower Right.
The second stamp has the blue outer corner Upper Right.
It is possible that we cannot see additional blue corners because of the overlap over the frame.
2pNGR 'dot in I of REPUBLICA' plate variety
This plate variety may be to the master dies used to complete the plate on account of me finding several variants of it.
On cover I find a variety with a blue corner Upper Left.
Here is the stamp...
...and details of the plate flaws.
I also find this stamp, and with a different set of flaws in addition to the one that sets it apart as this variety.
The variety is also found on the 2pNGR 'Servicio Oficial.' These two specimens have additional flaws that are different.
