I'd recommend JB Bobo's Modern Coin Magic and any coin dvd's from David Roth, Michael Ammar, and David Stone. If you want to learn more advanced coin sleights those are good recommendations to try out. If you want to learn hard-hitting coin effects you should try out Digital Dissolve-BJ BUENO/STEVE DUSHECK , Three Fry nice to put in your coin routine by Chris Kenner, Coinone by Homer Liwag, you should pick that one up,amazing coin guy! Also check out Silver Dream by Justin Miller, but I would just learn sleights from Bobo's and make my own effects adn you can go from there.
