Don't cry for Argentina 2b - General José de San Martín

After discussing the stamps of Gereral José de San Martín with open background, a second (smaller) group, is the one with plain background.

At first we split up the values by checking if there is a 'dot' next to the face value, or not.

'dotted'

no 'dot'

remark : the peso-values don't have a dot !

For the 'dotted' version, we have to check the watermark. First we check whether it is a sun If so, we have group 10 (N°s 385-396).
If not, the watermark shoud be a horizontal hexagon, which means it's group 11 (N°s 397-400)

The undotted values, should have a 'sun' as watermark, there are many different subtypes.
All have n°s 405-417 (with A, B, C, D, E, ...... subtypes) - group 12.
When there is no 'sun' as watermark, the last option is group 13, with watermark AP (Ahorro Postal).

WM 'Ahorro Postal'

As explained in my previous post, I refer to Argentinian catalogue numbering.
Other catalogues have way less different types. To each catalogue their own system of course.

In most cases the watermark will appear clearly, but don't be surprised if many of your General José de San Martín stamps only show parts of watermarks, unclear watermarks or "something that looks like a watermark".
