US Scott #596 Find - Impossible!

jimjamtwo - I assume you used a microscope to at least x100 mag, maybe x400 and a mini-grid slide calibrated to 0.1mm minimum to get consistently accurate measurements to at least within + or - 0.13 mm, some photos would be very interesting.

:)

Funny that I ran across this post. I have a post on stampbears that might interest you.

It is about #596 (or what appears to be one). I am not plugging that forum, I just do not have enough posts here yet to post the images.

There is not a minimum number of posts that must be made in order to add images. Simply upload it to a free Photobucket account and copy the "IMG" tag and paste it in your reply.

Thanks, didn't try that one.


#552 for comparison.





What looks to be my #596 - it is perf 11 and by my eyes, measures 19.25x21.75

It was probably from a corner of a sheet or possibly trimmed on the bottom as it it not quite as tall as my catalog says it should be. I added a line on the right side to help in comparing the distances.





The full image, without the imaging software ruler is shown below.

This is a Scott 552 probably from a booklet pane being the lower left corner stamp (pos 5) with 2 natural straight edges. Both the 594 and 596 are rotary press with the 594 being coil waste and the 596 being sheet waste.

The 594 can only have one natural straight edge (vertical) and the 596 cannot have any natural straight edges.

That is kinda what I originally thought, that is was a #552. The .25mm width difference and the lack of clarity led me in this other dirrection.

I would really like to know where you got your information from as I have yet found it elsewhere.

*I just figured that sheet waste would have a corner, since it had not gone through the perf machine yet.

I appreciate the feedback and if you are correct, it will not cost that much to get it cofirmed by an expert.

The following was taken from the recent sale of one of the known copies.

"At the beginning or end of rotary press printings, there was some leading or trailing paper that was too short for either rolling into coil rolls, or for perforating for 400-subject plates. In 1919, the Bureau devised a plan to salvage this waste by perforating and cutting the sheets into panes. These were put through the flat-plate perforating machine in use at the time, giving the stamps full perforations on all sides."

The first part of that statement led to my assumption(*) about the straight edges. The final sentence does lead me believe that you are correct.

For all you need to know about Washington and Franklin stamps and most American stamps go to
http://www.1847usa.com/

1847usa is a good site and worth time spent reviewing and researching.

That being said, there is no substitute for the interactive learning that happens on a site like this, though. There are a handful of posters here who can not only help with i.d. but also (take the time to) explain why.

Not everyone is able to clearly explain 'why' and not everyone who can explain 'why' is willing to take the time to do it.

I'll mention Russ by name because this was one of the threads where he hit it out of the park. (A baseball reference, for our overseas friends.)

I reread this thread start to finish because it was brought back to life again, and it was worth revisiting.

The first rotary press printed (coil) stamp was U.S. Scott # 459 which was imperforate from June 30, 1914. Rotary press sheet stamps mostly have big gum breaker lines on the gum side horizontally and small gum roller lines on the gum side vertically.

Which perforation gauge do Americans use to gauge American stamps, is the Stanley Gibbons "Instanta" gauge satisfactory ?
The Scott 581/596 Design Size is 19x22.5 as per http:www.1847usa.com/1922identifier.htm
or is this information incorrect ?

I use the Scott Multi-gauge. The preferred Perf gauge is the Kiasulas Gauge (Not sure if It's spelled correctly)

This stamp is a Scott 596, the information I have relied on is,
(1)Perforations 11x11 (exact gauge using Instanta gauge 11.4x10.8 )
(2)using, http://www.1847usa.com/1922identifier.htm ,to verify Design Size 19mm x 22.5mm
(3)Stamp is Rotrary using, http://www.1847usa.com/FlatPlateVsRotary.htm
(4) Colour variations, http://www.siegelauctions.com/enc/census/596.pdf

The perforations on both sides should be around 10.9 x 10.9 for flat plate printed stamp perforators which is what makes it rare instead of around 9.85 x 9.85 or 11.2 x 10.5 for the usual rotary press printed stamp perforator.

Most 596's with precancels only have the Kansas City MO. precancel that is printed on two lines.
It's the printed on two lines precancel and not the printed on three lines precancel which is mistaken for it.

Hi, Jogil,

Can you direct me to the source you have related to in relation to the gauging of the perfs ?
Only nine of the known thirteen are Kansas City pre cancels, the other have wavy lines possibly from Washington.

Hi Stewart. This is mostly based on the characteristics of those stamps that are related to U.S. # 596 to give us this information. Since U.S. # 596 appears to be a cross between U.S. # 552 with regards to perforation 11 and U.S. # 581 with regards to the rotary press printing, it is suggested that all who are interested in finding U.S. # 596 should get at least one copy of # 552 and # 581 for reference and comparison purposes. Also, a copy of U.S. # 632 would also help since this is mostly mistaken for it. There is nothing usually better than having the right reference stamps and using their characteristics for finding rarer ones (along with authoritative specialized philatelic literature references on the subject which is what you have done through your list above). For perforation measurements: # 552 Kiusalas 11-72 (10.94) for 11 flat plate, # 581 Kiusalas 10-80 (9.84) for 10 rotary press, # 632 both Kiusalas 11-70 (11.25) and Kiusalas 10.5-75 (10.50) for rotary press.
