Help With Understanding Imperforated Stamps

I am working on some 1932 plus/minus stamps. My album show many of the same stamp aka 3 cent George Washington,,, one imperforate the other regular,,, can any one show me a picture example of the difference?,,,

Left is a stamp from a sheet.
Right is the bottom RH corner of a booklet pane
Depending where the stamp resided in the pane
of six, the imperforate side will change.

Hi Rodney,

The stamps you show are not really imperforate. They are considered to have "straight" edges. The stamps were perforated and then cut for booklets. In cutting the perforations are trimmed thus giving the booklet stamp straight edges.

A true imperforate stamp will not have any perforations on all four sides. The stamps are printed and not run through a perforator.

Interesting Jerry.
describe a stamp from a booklet

surely something like 12 x imperforate?

also is one rotary press and the other flat plate perhaps? the design & vignette looks larger on one than the other. (#720)

Don't forget there are coil varieties of the 3-cent George Washington stamps, too. Here are examples of Scott #721 (perf vertical) and #722 (perf horizontal):

I dunno about that Rod. I think it's more common to see Perf 12 SE -- as in Straight Edge. Because the stamp would have been perf 12 on the right side also, if not for the fact that side was cut straight because of the booklet format.

With the coil stamps, like WT1 posted, I most often see them described as "Perf 12 Vertically" or "Perf 12 Horizontally"

I guess it's like the MNH M MUH debate -- there's more than one term describing the same thing.

P.S. and don't forget my Schaubek album, where coil stamps are indicated 12/-

Wow thanks all this will help a ton.... My mind was drawing a blank.

Hi

In the US, 19th and some 20th century stamps had a straight edge(s) depending on the stamp position in the pane.

I was wondering if there are any countries that had stamps with one or more straight edges, excluding booklet panes and stamps?

I just realized that I have never seen a Latin American stamp with a straight edge. Maybe I missed something.

Googled around and guess what? SCF had a thread on booklet panes:

The above shows why the booklet panes have straight edges.

Jerry, several of the Indian States (Barwani and Jasdan among them) only, or nearly so, issued their stamps in booklets. Some printings of Jasdan had straight edges, which helps identify the printings, like this sheet of SG 4:



Other States printed their stamps in full sheets, and again some printings had straight edges, which helps identify the printing. This SG 1 of Wadhwan



is partially identifiable by the straight edge.

Hi Tony

Thanks. By the way. What did they use to hold the stamp pane(s) together with in the booklet By the size of the holes it must have been one huge fastner.

Rodney: In Colombia there are varieties of stamps that are defined as "imperf between horizontally and imperf between vertically. Naturally these are collected in pairs.

Jerry B

Yes, I am siding with Kirk's explanation.

I am a Stanley Gibbons man.

Hi Jerry

I don't have a complete booklet of Jasdan - out of my price bracket - but I'd say it was probably twine. Barwani did the same with the booklets most of its stamps were issued in. You can see the binding holes in this sheet of SG 1:



Other times, they used staples, as with this booklet pane/sheet of the 2 Anna, SG 11 imperf between

doesn't imperforate mean not having any perforations..like this Hungary stamp ?

Yes,
but it can also be employed to indicate a side of a stamp when
described in written form.
eg p14 x imperforate.
Imperforate by itself, describes all sides.

Perforations on stamps, are described in clockwise rotation,
(incl triangular stamps I think)
Some examples of stamps have differing perforations
on 3 sides.

Rod, Ok..got it..i mainly deal with the totally perfless ones !!
