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.

One way of determining in the stamp is printed on chalky paper is to use a piece of silver wire. Carefully run the wire across one of the perf ends and if you see a gray/black mark the paper is chalky. But be careful, this method does leave a mark so alight touch is recommended.
