Grills: Question What Grill Is That And How Do You Know This?

Hello, I'm new here because I'm learning to know US stamps, especially older ones because I'm looking through some collection albums. I think the grills are very interesting, but I have just found some informations and I am not into that. So maybe someone can help me: What grill is that on the picture and how do you recognise that? Thank you so much!

The first answer is usually to show the complete stamp and both sides :).
The grill has to be counted the rows / columns and then which orientation the small squares are, normally vertically. Then you look into the catalogue and search for the grill that it could be.

PS: I forgot to say that the image of the stamp should be sharp (good) or maybe under oblique light.

Hi Elisabeth, I am not a collector of old US stamps, but grills are identified by counting the "humps".
You might go to www.Stampsmarter.org for a way better explanation

Thank you littbarski and Peter.

Why is the front of the stamp important? Do some grills only appear on special stamps? I can not upload a better picture, it did not work with the upload. I'm just wondering which grill it could be, and how I can go further in this theme, so thank you for the link, I will read it now #128578;

The item you show counts out as 14 "dot" columns wide and 16 "dot" rows high.

In the Scott U.S. Specialized Catalog, a grill array with these dimensions falls into the group "14 by 16 to 18 points" which is classed as an "E" grill.

i.e. All "E" grills are 14 points wide but their heights vary from 16 to 18 points high.

Please understand, however, that it is easy to classify a grill by these measurements, but to "authenticate" a grill requires much more information. At that stage we would need to ascertain the "shapes" of the grill points, which requires a much greater level of image magnification than what you have given.

There are other factors necessary for authoritative authentication of a grill, but your basic interest question over grill type identification has been covered.

Let's see if you can identify these grills (but be careful)

I will only say these are authentic grills of the National Bank Note Co.

Revised per a good suggestion.

Please also give us the front of the stamps

Let's see what you can say about the grills first.

Dimensions in points; disposition on the stamp, whatever you can see,
(whether it makes sense to you or not.)

Based on the initial inquiry, the goal of this exercise is first to count points, and then observe what you can of point shape, array configuration, up/down orientation, and so on.

What do you do when things don't look right? Or when there is an obstruction?

The first appears to be a D grill. The other appears to be a triple grill, but the image is not good enough for me to tell what grill it is.

Thanks for giving it a try, revcollector.

On that first grill, how do you count the point dimensions?

Book on the D grill is 15x 18-19 points.


for the second grill, the scan was 600 DPI. Here it is at 1200 DPI.



Your hunch about a triple grill is heading in the right direction, but this is a bit more off the wall than that. Some of it is hard to see, but look carefully at the corners as well as the center.

I think I'm going to send up some pics of the various grill sizes when I can find my pages that show that stuff.

I see evidence of grills on all 4 corners, plus a grill tilted in a different direction in the middle, like the sheet was flipped during one grill pass. Not being a grill expert, it's almost as if someone was practicing creating fake grills.

Gentlemen,
Don't get me wrong, but we seem to have lost the intent of the thread. Elisabeth wrote in part:


It appears "grills: lesson 1" is where we should be starting, yet we have jumped to "grills: lesson 10" with specialized items.

I am doing this from a phone, so….

Since the OP has apparently checked out, I am going to start a new thread to "introduce" all the grills. The plan is to have pics and discussion for each major and minor grill variety. "Minor" referring to sublistings. I have located my material, so I just need to get it together and make sure the images are up to speed for what we want to do. However, the B grill will only get noted in passing. (That's what happens when there are only four examples known.)

We will eventually get to the challenge items in this thread, so I will cover them when we do.

essayk and everyone else.

We have a basic tutorial on grills at the Stamp Smarter website, which can be viewed here. It was prepared by Don Denman and Bill Weiss.

This might be a good review for basic information about grills, then follow up with the tutorial here.

The first stamp is actually a "green 10" but it's not a Scott#89.
