I'm going through my Austria stuff (and was really making some serious progress!) when I noted that the SC# 110-120 is listed as being on chalk paper and on ordinary paper.
Other than the supposed (which is in doubt now from what I read) silver test, and I've never liked the idea of having to damage a stamp to identify it, obviously. What do you do to try to identify them? Ive got umpteen million (okay more like a few dozen) Cat #112's and 113's.. and I'm trying to find some way to identify if there's a difference between the two paper types. A lot are moderate to heavy cancels. So I'm not able to make out much in them in terms of the artwork on them.)
PS: I got the last batch of stamps today.. thanks Patrick!

re: chalk paper stamps... How do you id them?
You tell by feel, but chalky paper doesn't actually feel chalky -- it feels slick, like the pores have been filled with chalk and then buffed ie glossier than regular paper.
Try that description out when looking through your stamps and let me know if it helps.

On unused stamps, in addition to the "slickness" feel, the stamps also look polished, especially typographed stamps. Only the typographed stamps in your set were issued on both ordinary paper and chalky paper.
The chalk was laid out between the various sheets of stamps to try to keep them from sticking together. With engraved stamps, Roy's description is exactly what happens as the spaces between the line engravings gets filled with chalk.
