Default (RCSD) Chalk surface paper

Douglas,

so isn't the real problem to get coated paper distinguished from
non-coated papers???
And in such a way that the method will be non-destructive? Using silver
sounds like barbarism.

I'm not sure whether I can count on my catalogues as to what type of
papers are involved. Maybe in the early 20th century philatelists had an
obsession for chalky paper [not just Anglosaxon countries but also
Portugal, Switzerland] but later on - and certainly in the last few
decennia - hardly anybody cares for the paper itself. They may want to
distinguish types of phosphor and the like, but not the base paper or the
immediate coatings underneath the printing inks....


Except, maybe for those WEIRDO Belgian RR papers. :^) White paper,
phosphor, polyvalent, blah, blah, blah...
