Difference Betwee Coil/Reg Issue Stamps

Hi guys

Me again

I'm struggling with properly identifying US stamps that are either coil or regular Issue. Is there a website that explains the difference?

One of the answers I'm looking for is were all coil stamps printed the same way ie with the same number of perforations.

I think I've figured out that if the description says perforated vertically then the horizontal is straight cut and vice verse.

I've just received my perforation tool thing and I'm getting the hang of it so when my album gives the perforations for both sides I'm ok.

Sometimes it only states regular issue or coil and I'm not sure how to identify them.

Thanks in advance guys.

I think I understand what you are asking and I also think I MIGHT have your answer.

A coil stamp will always have two opposing ( usually if not always top and bottom) sides imperforated and the other two perforated.
Whereas a regular( or booklet pane?) stamp will not ever have the two opposing sides imperforated.

The imperforated sides are key(being across from each other) because sometimes you will have two perforations on a booklet stamp.

Maybe somebody more experienced will come along and back this up for me.

Thanks jser

I kinda figured that I was just uncertain if they were perforated horizontally or vertically or maybee even either ( if that makes any sense)

Hello Dianne.....

"One of the answers I'm looking for is were all coil stamps printed the same way ie with the same number of perforations.

Perforations are measured not counted.
Perf number and number of perfs are two entirely different things.
Coils & booklets were issued with a variety of different configurations of perforations.

Sheet stamps are the regular issues.....perfed on all four sides, although some were scissor cut from sheets and can have one, two or even three cut sides. These usually look like sloppy cuts, not square or parallel.

Sheet stamp #720 perf (type) 11 x 10 1/2 (same Washington as below)
On the sheet stamp 11 x 10 1/2 means that the top & bottom are perf (type) 11.....the sides are perf (type) 10 1/2 (all sheet stamps with a compound perf are described this way)


Typical horizontal & vertical coils....
Horizontal stamps, vertical perfs....#721 perf (type) 10


Vertical stamps, horizontal perfs.....#722 perf (type) 10


On album pages.....when there is no perf type mentioned but it is noted as a coil or booklet, look back a page or two to look for the last perf type mentioned, it follows until a new perf note is necessary.

Using your perf tool thing......a perf guage.
Be very careful to align perforations on your perf gauge exactly.

Thanks Tom

So what your saying is that regular issues are always perfed on all sides.

And yes I do realize that the perfs have to line up perfectly and I have Identified a few stamps using it.( though I did think the number ment the number of perfs and not a measure thanks for clearing that up).

I'll try again tonight and let you know how I make out maybee post 2 or 3 so you can let me know how I'm doing.

thanks again

OK I'm a little confused, modern US stamps are not perfed on all sides.
Do we not make sheet stamps anymore?

If not then I know we do now have booklet stamps that could have two sides imperforated because of being on the corner of the sheet.
Those two sides would be adjacent.

Jser

I hate to confuse the issue here, but it isn't safe to say that regular issues always have perferations on all four sides because some countries issue totally non-perferated stamps that can be used for postage. Souvineer sheets are one example of a place where one might be found.

Yeah, and certain ones as I stated before are from corners or sides of booklet panes and could have 2 or 3 sides perforated.

Hey guys

Now I'm really confused. Sat down again to try to identify them and was no further ahead. I think I set them asside and study the issue further so that I can better Identify the different issues of the same stamp.

Thanks for all your help

Dianne

To be simple
stamps with only two perforated sides and those two sides opposing will be coil stamps.







Jser

thanks jser

are they sometimes perforated horizontally

Dianne

Yeah, refer to toms photo above of the washingtons.
