Glad you are joining in on coin magic! Yeah, I would play around and get a feel for both sizes. I went to my bank one day and got soe half dollars and silver dollars. I didn't have to spend much. I started playing around with them. To me, is seems that the dollar sized coins look better with my hands, although I do use half dollars for certain routines (like Spellbound, as the English Penny is the same size). Good luck with your coin magic. I have found it is much more difficult to make coin magic look good. I have been practicing Eric's 4 Coins Across routine for a year and have only been recently performing it. Great DVD though!
