Are Illegitimat And Illegal Stamps The Same?

*** Moved by Staff to a more appropriate forum. ***
I understand that illegal stamps are printed without government approval. Is this the same for illegitimat stamps? If not, what makes them different?

Can you give us a little context into this issue? Perhaps the source or sentence that contains each. Thanks in advance.

As Partime suggests, the question is a bit unclear. Stamps are either legitimate or not. However, legitimate stamps can be used in illegitimate ways. Is that the distinction you are making?

I was thinking of the State of Oman issues which have been clearly labelled as illegal since there is no State of Oman and the Sultanate registered a decree. With Equatorial Guinea, on the other hand, there seems to be some evidence that the government issued contracts after the dictator President closed the main post office for about 10 years around 1971. If they knew of these issues, or contracted for them, would they still be seen as illegal or could they be classified as illegitmate?

Now that we know this thread is about the stamps of specific countries, I'm moving it to the appropriate forum.
