Varieties For GB Machin Stamps (Example 4d And 7p)

Hello,

some weeks ago I searched a lot information about the Machin series. I made some notes which I didn't want to forget, but now I have issues in finding the sources of information again :).

I noted the following varieties:

4d stamp (black-green): the value "4" is more close to the border than usual

7p stamp (red-brown), matt coated, 1 center band: there is more distance from the head to the border

which varieties could I mean and is there perhaps a SG number or link for me?

also, I noted two stamps which exist "uncoated", 3d lilac and 8p red, is this "uncoated" something clearly visible with normal (or even without) magnification?

thank you!

The Machins have "floating values"!

Not an expert, just reading a catalogue.

According to my 2013 Gibbons,
the 4d (deep sepia) 2 bands, or the 4d (deep olive brown) 1 centre band
are not listed as having different spacing.

However the 2d lake brown have different spacings, Type l and Type ll.

Perhaps you made an error?

Hi stamperix,

I find the Adminware site very useful on Machins.

For example, here's a link to their page on the 7p red brown:

If you would like more detail then the standard is provided by Douglas Myall's Deegam Publications:

thank you all. I looked at all the websites about Machin stamps and PDF files and catalogues, but didn't find my source anymore, not now either.

So I guess I was wrong making those notes, I thought I saw the information that the brown 4d stamp has the value shifted in error, as well as the 7p stamp had the head lower in error. If nobody has ever heard of these two errors, then they don't exist :).

The 7p variety I can believe. There are various head types, subtly different, and this may be one of them. From memory, some heads have more curved bottoms, some straighter, so logically the curved ones will be a fraction closer to the edge of the coloured area.

This type of detail is beyond my personal interest, however, so I couldn't confirm for sure. The 7p was in production for many years, so there will inevitably be minor varieties.

The 4d I have not heard of, and I am doubtful - although it's not impossible. I agree with one of the comments above that this may be confusion with the 2d, which had two quite distinct issues.

thank you for your answer. I think you're just right, I will look at all pages at adminware and just note which stamps have varieties of value shifting or head B, and when I once find another stamp which is not listed, it will be an error.

the following two questions still would interest me:
- is the "uncoated" variety of the mentioned stamps and maybe others just that: uncoated paper which should be recognized easily?
- how about the gum: is this only relevant for mint stamps or is there any way to tell a Machin variety that has been used, perhaps you can find indicator for the gum even after it has been used?

8p red in DEEGAM:

thank you Galeoptix. For sure I will buy one catalogue in the future, but about the uncoated paper: is this very obvious, or do we need a special trick to differentiate the uncoated variety from the others?

and any chance to know which gum was on the stamp once the gum is gone :) ?

I think I found the 7P I was talking about. I noted the head in a different distance than normal, but that was not the deciding factor.

the stamp is in the Connoisseur catalogue in chapter 2, number P70:
7P deep reddish brown, CB, thin numeral, head B1, cyl. 8, experimental coating PCP

the value is high, so I thought it would be because of the head, but now I think it's because of another factor - which one? what is rare about this 7P machin?

Just a question about a Machin, if I may. I have an NVI example (a 1st) which is on very thick plastic (not paper) but which doesn't look like a forgery. You'd have no idea that anything was odd about it until you touched it. Does anyone know what it is?

The 4d vermilion stamp from the "Stamps for Cooks" £1 booklet has a value that is set lower - closer to the bottom border - than similar stamps.
The 7p stamp, maybe, described the difference between the ordinary and regional stamps. The latter have the head closer to te right-hand border to allow for the regional emblem.

Several stamps exist with the uncoated paper variety.
