Once you have a 'grounding is the basics' I am sure you will find this place a valuable reference. Even if you are familiar with card or stage magic, you are going to have to start with the very basics. This often puts off card magicians, who have already spent years becoming expert at card manipulation, and just can't justify starting to develop basic skills all over again. Although it is understandable, it is also a little misguided. Every skill you ever learn in magic, every technique, every presentation adds to your abilities.
Coin magic uses the same fundamental principles of psychology, that all magic teaches.
Your finger dexterity, developed character persona and timing skills will fast track you through the basics in no time. It's really not difficult at all. One of the best kept secrets of magic, is just how easy most professional effects are to perform. Always remember that a good trick will make you look like someone FAR above the abilities of your audience. This is because it will not take you very long at all to be able to perform several 'stunning effects' that will make your audience believe that you have a full mastery of sleight of hand.
