Rotary Press Scott 578??

Hey guys can anyone confirm this as Scott 578 or is it a coil stamp or??Thank you so very much for your help

This is a SC578 postcard from my colelction - see any difference in the perforations?

sides looks a little more ragged but top and bottom of yours look the same as the sides on mine..am I corect? Is mine considered an imperf??

The 11-gauge top and bottom perforations are the differentiator.
Yours is a SC597, Mine is SC578. Don't feel bad - I have been looking at the back of postcards for 35 years [estimated 5,000,000] and found TWO 578's.

This my other one - amazing I can find anything around here!

Chasa whats the 578 worth these days,,my catalog is 2002??Question~ so I need to look for those 11 perfs across the bottom and tops then correct? I have hundreds I need to look at once again if this is the case

My 2009 shows it at $700.00 on cover.

Nice Stallzer! Guess thats what I'llbe doing here asap while fresh in mind! Thank you for your help

Here is one I've always wondered about but have never been able to positively identify. The year is correct, the measurements are good, but I struggle with my eyes to identify the perforations. With the White perf tips on the White background, the wavy line cancel and my Scott's transparent multi-gauge are not playing well together. i've wrote if off as a Perf 11

I count 11 as well ,,the same amount as SC578 ...why are you writing it off Stalzer..isnt this what were looking for here ??

The 578 is Perf 11 X 10 which I know mine is not. I'm holding out hope it's a 594 :) But my measuring devices are not that dialed in where I can positively measure a 1/4 mm. The stamp design on mine is 19x/x X 22x/x but all in all, I believe it's just a 552 Deep Green.

Stallzer I am goin on the hunt myself now!I am curious of these 5 stamps,,I will post here in minute
Ok I need some input..whats up with all of the different colors?
I think that bright green one might be something special there..I recall reading or seeing something to look for in those

Dark Green and Yellow Green

I hesitate to make the following comment, because it may come across as my being a know-it-all or arrogant. That is certainly not my intention.

To determine perforation on a stamp, you do not count the perforations along the edge of the stamp unless you can measure off a 2 cm distance and count them in that distance. That is what the perforation gauge has done for you.

For the counting method to work, you would have to assume that every stamp measured 2 centimeters in each direction which is clearly not the case for the Franklin stamp in question. What about stamps which are much larger than this stamp.

In fact for the Franklin stamp in question, there are 11 holes along the bottom, but 12 holes along the vertical direction. Are we going to call the stamp then perf 12 vertically. Of course not.

Please take this in the spirit it is offered----getting a sound method of determining perforation.

Absolutly will rohumpy andthank you so much for taking the time to explain not only for me but for many others I am sure.I HAVE TO GET A PERF GAUGE!

I rarely use my perforation gauge. An easier method is a direct comparison with a known entity.
For the 1922-26 series, if the vertical perforation [horizontal for the higher denomination 17cent-50cent] match up to 1938 presidential series sheet stamp [or any similar], then it is the rotary press later 1926 issue [11 x 10 1/2 perfs].
This method makes it much easier to measure on-cover stamps. A known perf 10x10 stamp can be used to match other perf-10's etc. Using this method I think you wil find that 4 of the pictured stamps will match the same as a presidential - ergo SC632. The dark one with left straight edge will not match the presidential ioperfwise, so it is perf 11x11. Only the NON 10 1/2 stamps need further study for identification.
