davidcyclebackI won't comment on how much, but old unopened cigarette packs can leak
some tobacco. I would guess the circa 1909 slide box pack (like a modern slide
box of wooden matches) would leak less tobacco than say 1920s boxes, which had
fold in tops like a Milk Duds box-- but that's just a guess. I had a carton of
sealed 1920s cigarette packs, and I can tell you that they leaked some tobacco
while sealed.
