Collectors Buying With Confidence – Ordinary paper, chalky paper, how do I know??
Hello again, welcome back. Is this something you have experienced? Happened to me only yesterday. Ordinary paper, Chalky paper, especially on many British
Commonwealth issues. I still find it difficult at times and that is
after reading plenty on the topic – which I might add has been written about
many times in many philatelic forums over the years.
Once upon a time I learned that the silver test
was the way to go. That is you lightly
touch say the corner of the stamp with a piece of silver and if there is a
reaction, a mark that is, on the stamp the paper is chalky paper, or chalk coated. If no reaction, then the paper
is ordinary paper. Of course this assumes you have a nice clean piece of silver
lying around. I don’t like this idea as I
guess it might be marking the stamp, and for Mint, not too a good idea,
perhaps?
Another view is what might be called the pitted surface test. This test
basically says if the surface of the face of the stamp has a pitted surface the
stamp is the chalky paper. If not pitted
in character then the paper is ordinary paper. You do need a very good magnifying glass of
course, which I have to say you should have anyway to study for printing varieties.
Mine is a $5 job from eBay. Works just fine. Really quite amazing little guy but not suitable
for more than the odd or occasional stamp study. You would not want to use it for too long,
ok for a few stamps at a time, and then you need to give the eye a rest I
suggest.
Just a few more comments. Chalk-surfaced paper produces a
crisp finish due to the smoothness of the surface. With ordinary paper, there are loose fibres on
the surface and the ink is able to 'bleed' into it, often producing some blurring.
I have also read another test is to look at a stamp
under a long wave UV lamp. If the paper
is very white it is chalky. I guess
different papers may have different results.
But at least these are a few ideas which might help.
Anyway, have a look and see
if you can try the pitted surface test to tell chalky paper apart from ordinary
paper. You might find some of your stamps are of a higher catalog value than
you thought. Then again, ….. well I
wont go there……….
Different British Commonwealth countries may also show
differently but as a general rule of thumb I believe this pitted surface distinction
is a reasonable guideline to go by.
Have a philatelic weekend, be
careful out there 😊
