Who knows the worth of these stamps?

Hello, does someone have knowledge about these stamps?
I found these in a book of my great grandfather.
Can't find anything about the first stamp.
The second poststamp I can only find in red but this one is purple,..
Kind greetings,
Elijah

 

Honduras 1914 or 1915 Service ca.$ 20.- cat.value
Guatemala ? don´t know
Transvaal-Pietersburg (South Afrika) 1901 forgeries are common,cat.value
for genuine ca.$10.-
New Zealand (?) no postal issue (as far as I know !)

 

Thank you very much for sharing your knowledge. I find it strange that the same Guatemala stamps are all in red. And this one is in purple. Do you think I could be a error in colour?

 

Thank you very much for the welcome, Molokai. Great to hear I'm on the right website. Wishing you a good day or evening.

 

Elijah,
What makes you believe,that the Guatemala label is a postage stamp ?

 

As you might know I have no knowledge about this topic. I found this Guatemala Stamp/label in my great grandfathers book. So I presumed it was a stamp.

 

Hi all, I think the New Zealand one is a railways parcels stamp
