This 2c National could have two grills, H and I;
"H. Grill about 10 x 12 mm (11 to 13 x 14 to 16 points)
I. Grill about 8 1/2 x 10 mm (10 to 11 x 10 to 13 points)
On the 187 -71 stamps the grill impressions are usually faint or incomplete. This is especially true of the H grill, which often shows only a few points." |

Impossible from this scan. It needs a bit of graphite and a much better scan. |

Using Graphite to study grill points
Here is a handy tip which can be used to detect or study grill points by transferring graphite from a pencil onto the
grilled area. The graphite/lead adheres to whatever points protrude enough to allow some to stick to them, making
them easier to observe.
1. Take a pencil which contains softer lead and deposit graphite from the point onto a piece of paper by rubbing
back and forth until you have plenty on the paper;
2. Use your finger tip to transfer some graphite from the paper onto your finger tip by rubbing your finger over the grill area;
3. Now rub your fingertip gently over the grill area. You should now be able to see grill points much more clearly than
without the graphite enabling you to study the points and count them if you wish;
4. The graphite will NOT harm the paper, but if it bothers you, it is easy to erase using a soft eraser. |

Not picking on the previous poster here. Applying graphite to the stamp is not a method that is accepted universally. In fact, I cringe every time I see it recommended. There are other methods that don't get the stamp, well... dirty. Find another method such as using fluid or oblique lighting. Even better would be to find a stamp to study with a complete grill so that it is actually identifiable.

Properly applied, there is very little "dirt" on the stamp. Fluid and oblique lighting do not always work well enough. |

The rule of thumb on these seems to be, from what I have seen, that you consider them to be H grills unless you can clearly see an I grill. |

1. Scott is very clear on this topic: if the grill is not completely visible, it is to be regarded as the H grill.
2. Don't just jump because one respondent says it needs graphite. I was able to count 15 points vertically in the original image (left side). It is unquestionably an H-grill. The mess you made of it with the graphite need not have happened.
3. I can see lines where you applied graphite with the point of a pencil. Big mistake. You should have asked how to apply it to a stamp. Your drawing obscured the very thing you wanted to reveal, and with a bit of patience you would not have done that.
If list members want to advise the use of graphite, at the least provide some reminder note on how it is done or a link to some instructions. Please don't put destructive tools in the hands of newbies. |

Someone who used to certify stamps (PF I believe) with the initials R.D. in a conversation mentioned how much he hated collectors that used graphite on the backs of stamps. |

The quote I posted, (alas to late in this thread), was taken from Bill Weiss.
We all have to decide for our self's whom to trust. |
