It is extremely smooth and silky to the touch. It is not a thin paper, like paper 9a is." -this is not accurate. <br /><br />According to the Duckworth (2nd edition 2008) paper 9 is separated into two types 9A and 9B which both are very thin (there is no 'basic' paper 9) The description in Duckworth is has somewhat ambiguous/non substantiated historical reports about paper 9B as far as details go. However i think it has been generally agreed that paper 9A is thin soft and white and fragile (white due to the china clay mineral that was added to the paper pulp as was for paper 8. The china clay silicate particles/powder can be seen under high magnification, 20x or more and also as tiny reflective flecks if held at various angles to a light source) The paper 9A is thin approx .0022-.0024" (i have measured,) with a 'fragile' appearance and does have a mesh vertical or horizontal that is quite obvious if laid on a black background or looked through to a lightsource . The fragile appearance is probably due to the clay mineral added to the pulp during paper manufacturing which lessens its strength substantially. The 6 cents for sure exists on both pl 1 & 2 and are the least rare. The 9A probably exists on the 1ct , 2ct , 3 ct according to the Duckworth description.<br />The paper 9B very thin paper on various denominations is less fragile appearance wise according to Duckworth (perhaps due to less or none of the china clay is what i believe) measures .0022-.0024" and is generally later printings. <br /> The 1/2 cent is a whole different area of paper study as there are quite a number of thin & tissue thin papers for the 1/2 ct which is more part of the small queen era for period of issue and probably does not exist on 9A.
