Tina,
When you manage to make the scan bigger please post a pic. I have the decimal set [see below] and would love to know if there are any differences apart from the value.
This lovely strike post issue was for use in Glasgow [Scotland] if my memory serves me well [Which it may not,so if someone more knowledgable than I will come forward.....need some help from someone else in Israel methinks!]. Contrary to Warrehouse's idea I believe your Olive green example to be the lower value but I have not found a pre-decimal set yet.
Still looking......and good luck Tina !

In the meantime, the decimal set***

*** Many strike post stamps in the UK were issued in Sterling and decimal values or overprinted. The Postal strike was ongoing when decimalization came about. I wish I had been a strike post collector then.....but sadly I did not even collect !
