Well as you posted this thread in the coin magic section I'm going to assume you mean coin trick suggestions. (Correct me if I'm wrong, in which case I second JFergz) For coin work, do anything that doesn't involve a table. So any 3Fly routine, or copper silver. Or do something in their hands. Basic vanishes and reappearances work great if you build a plot around it. I personally have used a one coin routine where I vanish a coin and pull it out of random pieces of both mine and a spectator's clothing, with a discussion of the money that goes into creating things we use everyday, like clothes. If you know a bunch of basic sleights you can have a lot more freedoms. Just make sure your reappearances are just as magical as your vanishes. Hope this helps.
