I recently watched a kids magician at a local library. He has a nice routine about catching reading bugs. He does balloon animals first, then magic. He does a quick appearing wand, them into sponge balls. He then does Bill Abbot's The Thing, and then into professor's nightmare. He then does a ripped and restored newspaper, and I believe he ends with Chris Capehart's Miser's Dream routine. Not sure of the order, but those are the tricks he does for a 45 minute show. You could adjust the patter and shorten the routine for however long the show should be.
I just took a look at this. Does it involve only coins?
