Hey guys. Im just starting out in coinm agic and this weekend im gonna go to some coin shops and stuff to look for some half dollars. This is a really ameteur question but how many coins do you need for a 3 fly routine. Do you need any shells? I am planning on buying metal by eric jones. I understand that people do not want to reveal how three fly is done but i think its pretty obvious that there is extra coins so i just want to know how many i need. I dont wanna buy four go home and realize that i need five or six plus a shell or some other gimmick
