Red Penny Can't Figure Out The Numbers

Hello Dodo335,
You could see a image of your stamp here-
https://www.stampworld.com/en/stamp...ps/1920-1929

That looks like a 'Large Crown' Type II. You will find it on the later 'Penny Red' stamps, both that 'with stars'



and that with 'letters in all corners,' aka 'with plate numbers'

The other stamp you posted is not known as 'Penny Red,' even if it is a 1d stamp that is red.



It should have this watermark 'Imperial Crown' but was reported on a watermark 'Orb' that was used for contemporary fiscal stamps. It is unlikely it exists.

Half penny green

Edward VII.

This also has the Imperial Crown watermark. There are four of them.

It was first printed in a blue-green colour by De La Rue.
The colour was changed to yellow-green.

In 2010, De La Rue had lost the contract. Harrison & Sons printed it.
Harrison & Sons used two different perforation gauges: 14 and 15x14.

All greenish blue stamps are De La Rue.
All stamps with perforation 15 (horizontally) x 14 (vertically) are Harrison & Sons.

Yours looks yellow green.
Measure the horizontal perforation. If it is 15, you know for certain which printing it is.

Thanks NSK,
I will take them for evaluation...
I have so many others stamps...

I'm not sure what you mean by taking them for evaluation, but what you've shown here are common stamps that don't require the services of a valuer.

Ohhh, OK. Nothing special then #128513;#128517;#129318;#8205;#9794;#65039;
