Here is my 211B, not a perfect copy, and a 210.
The 211B has a PF cert.
Yes, it has the cross hatching, but you can really see the difference in the impression with this stamp. The analogy you can use would be the difference between a coin that's shiny that you find in your change to a proof. This stamp has a proof-like impression that is so much more detailed and beautiful than the 210.
Hope this helps, Ray
