Booklet panes are the source for most of the different Machin varieties.
Identifying the source of a Machin single stamp is perhaps the most important part of understanding
and studying Machins.
This page includes a summarized list of all of the booklet panes that have a Machin stamp. Links
to full-pane illustrations are included.
Identifying a single, water-activated, stamp from a booklet
How do you know that a stamp came from a booklet pane? A single stamp, extracted from a booklet,
will fall into one of the following categories:
1. torn on all 4 sides (ie. from the 'middle' of the pane; this will look just like a stamp
torn from a sheet of 100 stamps)
The 'trick' to identifying the third type is to look closely at the perforated edges of the stamp.
During the printing process, the booklet panes are cut from the larger printing sheet of stamps.
When the consumer removes a single stamp from the booklet pane, 1, 2 or 3 sides will be torn
from the rest of the booklet. Upon close examination (and practise), it is possible to identify a torn edge from
a cut edge.
2. imperforate on 1 or 2 adjacent sides (not many Machin booklet panes appeared this way;
these are easily identifiable)
3. cut on 1 or 2 sides (the source of the vast majority of Machin singles)
[A stamp that is cut on 2 opposite sides is from a coil, not a booklet.]
