re: Help Identify Varieties of SC#554 (Washington A157)


1.Description of the stamp:

Washington A157
2 cent Carmine
Perf. 11
Design size: 19mm wide x22mm high

I killed four birds with one stone i.e. uploaded one image to show horizontal and vertical perforation sizes and two-dimensional design sizes. It saves time and space although it is not perfect. You need estimate vertical perforation and design sizes by moving ruler scale to zero point with your eye balls.

2.I have some questions about the red line on the bottom such as
(1) Why did the red line replace the perforation on the bottom?
(2) The distance between the end of top and the top red frame of stamp is about 2mm but the bottom distance is about 1mm, why did 1mm lost at the bottom?
(3) How to identify the whole size of a stamp is correct and therefore it is original one instead of a fake?

Your commets woulc be greatly appreciated!

Peter

Peter - this stamp is obviously from the bottom of the sheet. The red line is a printed cut line marker. The individual sheets are cut from press sheets and then perforated. The line help them line up the sheets in the shear machine. These are not unusual and in some cases a straight line cut could come from a booklet pane, but in your case I am quite certain is just a stamp from the bottom row on a sheet.

Peter,

The line at bottom is a guide line for cutting the press sheet into panes, as Dan said. Each press sheet of this issue had 4 panes, so this indicates that this stamp is from one of the top two panes of the press sheet. More importantly, this also tells us this is a Flat Plate printing since the Rotary Press printings didn't have guide lines. (Rotary Press coils DID have similar lines on coils, but the two are unrelated). If you see a guideline on a sheet stamp, it's Flat Plate. If you see a line between a coil pair, it's Rotary Press.

Dan is right that lines are possible on booklets, but booklet singles of that issue ALWAYS have a straight edge to the left or right and MAYBE one at bottom.

re: Help Identify Varieties of SC#554 (Washington A157)

Dan & Lars,

Thank you very much for sharing your valuable experiences how to identify the stamp with red line at bottom. More important is I have learned that the red line is an indicator of Flat Plate printing. May I expand Lars statement from bottom to all of four sides? I can easily find those stamps with red line at the end of top, bottom, left and right from my collection. What is more that I find a couple of stamps in my collection are imperforated at two sides. I am presenting one of them here. Please share your comments. Thank you! Peter

" .... (Rotary Press coils DID have similar lines on coils, but the two are unrelated) ...."

If I remember correctly any lines from rotary stamps are from tiny miniscule gaps between the curved plates that are attached to the printing drum where excess ink tends to gather and were unintentional. To some collectors they are a detriment while other might seek them as a sure sign of a rotary plate being used.

Peter - this is an example of a booklet pane stamp, bottom left corner. However the red line is not a guideline, it is a portion of the border from the adjacent stamp from being slightly out of line when sheared. Notice how the perfs on your stamp penetrate into the frame on the right. - Dan

Also notice how the red line doesn't extend the full length of the stamp.

Sally- I notice that the red line on the second stamp doesn't extend the full length but the first does. I am wondering why is that?

Sally & Peter - The partial red line is from the adjacent stamp and is the right side of the frame that goes around the image. It was caused by mis-alignment in the shearing process and actually cut off part of the adjacent stamp. This is very common with booklet panes. You should be able to note that the red line is the same length as the frame line on the stamp.

That's why I pointed it out. If it was a guideline, it would extend the full length of the stamp, right?
