I still believe that any stamp that commemorates anything or anybody cannot be considered a definitive which would include Israel's 50th Jubilee Anniversary issue and items like those Machin Anniversary SS.
This could get very interesting.
After reading the latest posts I can see a trend developing.
Catalogues do not agree on too much, one to the other. So it can be with this subject too, plus everyone else's definition of it.
Israel Post issued the 50th Anniversary stamp as a definitive. In all formats, that's what it is. Yet as Litho so rightly points out, it was issued to commemorate something.
So too the Hindenburg Memorial issue and [maybe too] the Birthday issue.
So let's take it a step further and make it even more complicated.
Lithograving said the Miniature Sheet to celebrate 40 years of the Machin was a commemorative issue. He is right.
Yet the Ruby definitive was issued for the Ruby Anniversary and yet it is obviously a definitive and appears on all lists as such.
Let's look at it another way.
If I cut out the two £1 definitives from the sheet it would give me a Se-Tenant pair. They would be of the same design, same value but just a different colour. That colour would then be the difference between being a commemorative or a definitive ? And if that pair were seperated and placed in a Machin collection of definitives, would anyone know the difference ?
In the year 2000, a two-coloured Machin was issued to celebrate the new Millenium. Royal Mail issued this as a definitive to replace the regular 1st Class value for a period of time. It is still valid of course although no longer available at Post Offices.
And yet SG catalogues lists this as a commemorative !

It can be found on most 'definitive' lists but not in the main listing of Machin definitives. It has not been given a 'Y' prefix like other machins.
Many other 'definitive' stamps can be found in sheets commemorating something...and these issues appear to be the borderline cases.
Do we go with the issuing authority, the catalogues [which don't agree one to the other] or our thoughts and opinions ??
Indeed, will we ever be able to truly define all 'definitives' ?

Edited to say I had a temporary memory loss earlier. 1st and 2nd class Definitives do not have a SG 'Y' prefix !
