1 Cent Franklin Perf 11 On The 3 Sides Could It Be The One.

I came across this today out and about. There is a green line on the right side I thought it was a booklet stamp line. Did they

2nd one top left

Do you mean bottom row, 2nd stamp, green line on left?

Kingstonstamper, please give us a close-up of the stamp you are talking about.

What is your question exactly?

Find a Scott 597 coil and compare width, then compare width with a Scott 552 and report back with scans of the comparisons.

Kingstonstamper,

552a?

I take it back. The stamp appears to be a rotary type. Seems a bit wider than flat plate types. Also, note how the top and bottom perforations seem to line up.

It is time to stop the guessing game. The stamp shade is typical of a flat plate printing. Rotary press colors are more of a dull green or a yellow green. If the stamp is slightly wider and shorter than a flat plate sheet stamp, it would be 552a booklet pane single. Booklet panes were printed on horizontal grain paper to better control shrinkage that would affect the cutting of booklet panes from sheets. After flat plate booklet pane production was replaced by rotary press printing, remaining stocks of "special paper" was used to print high value regular 1922 issue stamps, some E13 special delivery stamps, some C11 Beacon airmail stamps and the 1928 printing of the Special Handling QE1-QE3 stamps.

The size difference between rotary press and flat plate is more pronounced than between regular and special paper. All of this is well documented in posts on this site. The best source is the United States Stamp Society site. Membership is not expensive. Perhaps if more posters here were members the quality of posts would improve.

Clark,

The color of the stamp appears to be consistent with a flat plate 552a. What I can not understand is how the top and bottom perforations seem to be lined up vertically. This would be consistent with a rotary type stamp. Do you have an opinion on this stamp's ID? I am a member of the USSS.

Jack,

There is nothing preventing flat plate top and bottom perforations from being aligned between rows. Since the relative alignment is random, the probability of more than two rows being aligned is quite low. The rotary press bar perforator rows must be aligned because of the design of the perforator. Flat plate perforation wheels are set up independently and could potentially drift relative to adjacent wheels over time.

The stamp is probably a 552a single, based on the observation that it is slightly wider than a normal flat plate sheet stamp. However, because of the poor background, I cannot visually confirm the ID. Under better conditions booklet pane singles are visually different from normal flat plate sheet stamps. If a 552 and a 552a singles are placed side by side, they will look different to the trained eye.

It matched the 597 Coil on the page in the roe of Coils.
