Mexico #3 And 3B? Or A Reprint?

Scott describes a #3 as yellow green (first stamp), but the second stamp has me unsure. #3a is described as a deep blue green shade. The second stamp seems to be just blue, but this color is not described in the Scott catalog. Any shared expertise would be very much appreciated.

(The title should read #3 and #3a.)

Non expert.
Suggestion.
Stanley Gibbons SG 213 Queen Victoria
Changed from Blue green to Blue (common)
So perhaps a "colour changeling" (Exposure to Light damage)

That seems reasonable. For comparison, here's a more typical example of the blue green.



And here is a badly faded example of the yellow green.

What adds to my confusion is the face that it is signed by "Mevia-Madrid" on the reverse, indicating that perhaps it is exceptional?

A check of Greg Nelson's huge inventory shows no such animal.

The back stamp is actually Manuel Hevia of Madrid, 1898-1984, member of A.E.I.P. 1954-1956.

Interesting - that's the mark of Manuel Hevia (Madrid). Have not seen his mark on Mexico before, but I'm not certainly no expert in this area.

So whether his mark is there due it being an unusual shade of the 2r value is unknown. Think you'd need someone with access to a Follansbee catalogue to weigh in here (I don't have one as yet), to see if an actual blue variety exists as opposed to this being a discoloured blue green.

Edit - what rogdcam said :)

The Hevia mark is just a dealer's mark Like Stolow's where he guaranteed the stamp sold. In other words, if it proved to be a fake, you bring it back and he'd know you bought it from him, and he'd refund your money.

There is no blue shade listed by Follansbee. Deep bluish green as noted before exists, but this one is not that. The VERACRUZ needs to be checked out.

EDIT: VERACRUZ has two types listed by Celis Cano, both with bullets (raised dots) at each end, not the funny jagged character in front of the "V"; overinking would probably not do that. For the unreadable cancel on the blue stamp, the Schatzkés cancel book has nothing that matches.

For the left stamp, that's a San Luis Potosi cancel, Schatzés 1442, fancy frame with an integral date of 1857 at top.

Great info hy-brasil!

Also, this page on the MEPSI site may be of interest - showing the range of shades found for the 2r value.

Opinion.
I think the VERACRUZ handstamp is genuine,
or, both are forgeries.

My poor scan was made in 2010, hence the quality.
Make you own opinion.
The second "R" left vert leg has a pronounced slant on both opts.
The thickish "Z" also.

We have to take into account wear of the typeface, over time.

For the signature on the back,
Was there more then one type?
(Other then the one rodgcam provided)

Thank you to all who shared their knowledge. Considering all of the replies, I am thinking it is a 3a that has evolved to a blue shade through fading and/or light exposure. Thank you once again. What a wonderful resource this forum is!

While I collect Mexico postal history, I have no experience with the early stamps.

However, I asked a dealer friend and past president of MEPSI, who specializes in the Dos Reales issue, to look at this thread, and his response is that the blue stamp is most definitely a color changeling, probably treated with chemicals or bleach.
