3 - Grill 3-Cent Washington Help

Found these in recent collection. Not expert on grills. Can anyone give advice

Look at the grill like it's a spreadsheet.
It has 14 columns = "E" Grill, #88
"F" Grills are the most narrow-- 13 columns or less = #94

The wider the better--
The "D" grill has exactly 15 Columns, #85
The "C" grill has 18 columns and the points come out of the front of the stamp instead of the back, #83
The "A" grill is all over the stamp, #79

You won't have a "B" grill-- only 4 in the world

The "Z" grill is the size of the "E" grill, but the points are horizontal instead of vertical- #85B

Hope this is helpful for you,
Ray

That makes since. I could not get that from the internet search. Still can't tell difference in vertical and horizontal.

Thanks!
