Default (RCSD) Chalk surface 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.
