So much silly speculation in this thread. The top 2 causes for the "snow effect" is what Dan said in reply #2 or what Bruno said in #3. It is either ink &/or surface removal from cards sticking together or from gum sticking to the cards. The third option is that the wax pack pulled off some of the surface as the pack was opened. There really isn't a 4th option if you pulled them from packs when they were new products. Wax packs opened many years later produce a much worse problem with wax stains on the cards and the gum completely dissolving into dust. Both of which totally ruin the cards they are contacting!
