Okay, so because my birthday was a few days ago I got Bobo's Coin Magic for myself. Then I got it in the mail and realized something: I know a lot of coin tricks use half dollars and I don't have any... So before I delve into the depths of the book I have a question: What coins do I need to use Bobo's Modern Coin Magic to it's extent. I know I will need half dollars, but how many? Will I need silver dollars? I want to set aside a small box, or bag, or something of coins dedicated to magic so I would like to know what coins I need and how many of each.
