(RCSD) Chalk surface paper
Another way to tell chalk surfaced paper is to hold the stamp to the
outside of your (dry) lip - chalk surfaced paper will feel noticeably
colder & smoother than ordinary paper.

How can you tell if a stamp is chalk surfaced or not?
Chalky paper, used especially on British stamps, is easy to identify.
Chalk-surfaced stamps when rubbed with silver will leave a black mark
on
them. Be careful when testing these and just touch a small corner or
part
of the stamp.
You can sort out some of the modern ordinary & chalky paper stamp
issues with an Ultra-Violet lamp.
