Help Requested To ID Central And South American Stamps

I've got a few hundred Central and South American stamps, but I've never really looked at them until I turned off the TV last night. These are some of the ones that grabbed my attention. I'd greatly appreciate IDs/CVs for these:

(1) Paraguay. The stamp with the most economical overprint I've seen so far - just one letter ('C'). What is it?



(2) Mexico. This looks the sort of stamp that should be easy to identify, but it's not in my SG Simplified.



(3) Mexico. By sheer accident, I found this stamp selling on ebay. The seller says it has a CV of $250, but I'm sceptical. Can anyone tell me what it is and if there's a variety of this issue that actually does list for $250?

(4) Two individually-numbered Nicaraguan 'consular fiscal stamps' that have been turned into something else. The first is one of a number of 20 centavo airmails.



This one appears to have been transformed into a 5 centavo postal tax stamp:



I can only assume they had way too many of these consular stamps!

Does anybody know anything about them? They seem like the kinds of stamps that might normally not be listed.

Jim, I know you live far away in Australia and should be forgiven for
that reason.
But. Mexico is located in North America.

As is also Nicaragua.

lithograving, I've altered the name of the thread to something more appropriate!

Hi Jim

I don't want to be fussy but even though Nicaragua is in Central
America which is part of the North American continent, Mexico is
definitely part of North America not Central.

Latin America would be more appropriate.

I get the impression that the distinction North / Latin is made much more in North America than here in the UK.

I would normally think of three categories: North / Central / South. I don't often hear people here referring to "Latin America".

It's interesting that SG lists Mexico in their Central America catalogue but they're stamp dealers not geographers.

The Paraguay issue with a "C" represents "Campana" translated to "rural" a local use only, prohibited from use in the capital of Asuncion or mail abroad. Scott L22.

Mexico 1st shown, Scott 307, 1903.

The next one is Scott 710, unless it is unwatermarked then 710a
if unwatermarked it is worth what they are asking.

The Consular stamps are not listed in Scott or Sanabria Catalogues.

Thanks so much for your trouble, warrehouse!

I'm intrigued that the Nicaragua airmails don't rate an entry.

BTW, what kind of watermark(s) appear on Mexican stamps? I can see something on one that looks like a star.

The Watermark is a #156, with the word "CORREOS" at a 45% angle. 4 lines of "CORREOS on each stamp.

This is a very small stamp, so the script would also have to be small to appear four times on it!

Was this the regular Mexican watermark, or did they vary quite a bit?

BTW, the SG online catalogue doesn't list any Mexican stamps for 1903 at all.

Hi jimjamtwo,

The first Nicaraguan consular stamp with the overprint is SG 1419 / Scott #C462 from 1961.

The second one is SG 1358 / Scott #RA63 from 1959.

Thanks, nigelc!

Anyone who wants one of these stamps is welcome to contact me, since I don't collect Nicaragua.

Philatelists are not geographers?

Bravo to Lithograving for being precise in these matters.
