Okay so I wanted to learn some coin magic and decide to pick up ThreeFry because it teaches basic sleights for coin magicans. And the fact my parents got tried of listing the cards springing over and over again. On ThreeFry I use quaters because I don't have sliver dollars. Is it okay to use quaters because Chris says to use silver dollars because it easier? Note that I don't have the biggest hand out there maybe a medium size hand. What coins to yall use when praticing ThreeFry?
