thx Don

Hey, Don, that is a well-thought-out table. Very informative. Who does the entries in StampSmarter? Specifically, this table? I've seen lots of reference materials that (try to) cover the grilled issues. This table seems concise and it's easy to understand. Now all we have to do is to be able to SEE the grill points clearly on the stamps in question! If this is your work - Thanks!! It makes this field a little more clear.

Thanks for the kind words, Bill and I worked together on that table.

I used a Sonic Imagery Labs US Specialty Precision Multi-Gauge to correctly identify an I grill (SN #134A) as corroborated by a PSE certification.

I suggest purchasing one of your own here - http://www.slingshotvenus.com/stamp...tyPerf5.html

Thx Pascoe I've got one, I must find it!
