Sack's Spotted Sorcery
Sack's Spotted Sorcery makes for a great pocket trick, as it only requires two small dice, which can be readily found in many homes.
This routine by Dr. Theodore Sack was originally published in The Phoenix #152 (June 1948), then later included in Bruce Elliot's book The Classic Secrets of Magic. (1953)
The bonus routine demonstrated is "How Many?" from The Magic of Gerald Kosky (1975) or Routined Manipulation Finale (1976) though it is not far off from any standard two-in-the-hand one-in-the-pocket style routines, with which you can substitute dice.
