Mexico 1899-1903 Definitives Printed In The UK In Recess By Bradbury Wilkinson

A fine set of definitives was engraved and printed in the UK by Bradbury Wilkinson, New Malden. A few values had to be re-issued in different colours - due to a postal rate change? - in 1903. One might expect BW to use the same printing plates again OR having new plates made from the same original engraved dies. However, when you really pay good attention, you will see that BW had made NEW engravings for some values. Not for all [10c?] as a minute detail keeps popping up in the new colour as well!

Hello,
At the bottom of the 2Dos green stamp I do not see the network of lines characteristic of the engraving.
Can it be lithographic printing?
Excuse me if you find this an idiotic question, I'm a beginner collector.

I have absolutely no idea what any the above images are supposed to represent without any labels as to Scott numbers, old/new engravings, etc. What do the enlargements mean? What do the circled dots mean?

Cupram,

No, both are in recess, the fragments show characteristics that are different between the two colours [1899 vs 1903]; the encircled dots of the 10cts stamps are dots that do NOT belong to the engraving but are present in EACH stamp both of the 1899 and the 1903 printings. This might point to a common plate for both!

John,

at the top I explained what this is all about: a change of colour that should NOT have urged to new plates/dies! Yet, they are different for the 1,2 and 5c,probably for the 10c as well, although I may hsve my doubts!

I never use catalogue numbers as it suffices to have mentioned the year of issue! And the pictures are usually better that what you can see in any catalogue ;)

Galeoptix, Then we will have to agree to disagree. I hope your post has value to others.

John,

Those who collect Mexico might wonder why this wasn't told them before!
