Help With Paper Types On A Germany SC 342

Both Scott and Michel list two types of paper for the 60 Pfennig SC 342: usual and chalky. It's my understanding that chalky paper has a glossy or matte finish. I don't know how "glossy" the surface has to be to be considered chalky. I don't have another 342 for comparison. Does anyone have copies of both that I could see for comparison? I don't know how well it would show in a scan but I thought I'd ask.
I have two spaces on my Steiner page and I would like to get the stamp in the right space.
It's a lousy copy but what intrigued me was the date. Chalky paper was used in 1928.
Any help or comments would be appreciated.
Thanks!

As an aside, I checked Germanstamps.net. It looks brighter than the usual paper type shown but not as bright as the example of "glossy" on the site. Another pair of eyes would be helpful.
Thanks!

Hi Dan,

If you rest a chalk surfaced stamp on your top lip it will feel 'cool' compared to a non chalky.

Thanks Bobby,

I'm deconstructing an old collector's album. That stamp has been God knows where. It's going to have to have a long soak before it gets to my lip!

Michel 362y is on the right. Under 10x magnification the printing on the chalky paper appears to be a little bit sharper.

"Glossy or matte finish" -- those two are mutually exclusive. This is a coating of the same stuff on magazine paper, but slightly thicker, and that can appear glossy or matte depending on how it's processed.

Thanks for the back shot but chalky paper only has a coating on the face. For this stamp, the stamp paper will probably be noticeably whiter also; that shows in bookndrbob's scan above. Bobby De la Rue's test is very good also.

The traditional test is to touch a real silver coin or ring to the face, in the margin. And that means the lightest possible rub, not trying to scrape the paper. That will leave a gray mark that can be gently erased with a soft plastic art eraser. Mars Staedtler is a good brand for that and general cleanup of light dirt and pencil marks.

British Commonwealth from Victoria to George V often had stamps with both normal and chalky papers. You'll find light scrapes on them sometimes from collectors doing the test badly. These can then get mistaken for removed pen cancels.

I think I read that soaking removes the chalk to some degree, so that test may be nullified.

Is this what your looking for ,my collection

Notice when compared side by side the lettering appears larger on the lighter stamp chalky paper .

Thanks to everyone for your input! The side-by-side examples were especially helpful. I hadn't noticed the difference in the lettering before.
Thanks!
