2 Cents Jackson 1861/67 With Grill Identifying

Hi everybody,

I am classifying this stamp perf 12:





The truth is that it is difficult to see with the naked eye but with some light a grill can be observed.



The previous owner wrote 29A behind the stamp but I think he was wrong. It seems F grill to me if it is a real grill.

What is your opinion about grill? Which Scott number could be?

If it can helps, the feel of the paper in hands is very thin.

Thank you very much to all

Someone with a Stanley Gibbons catalog can confirm, but I think 29A is the same as Scott #93. So someone agreed with you on the grill. It is impossible to confirm from these images though.

Difficult to tell, but maybe not impossible. I think I can count 12 by 14 rows, which puts this in the F grill zone (with an error margin owing to the quality of the image).
