High. For a number of years I was very active in magic. For various reasons I have not actually actively been into it for the last 6 years though. I dabble here and there... but I just didn't have the spirit for it that I once did. Recently I have rekindled my interest and just recently went digging through my supplies to see what I wanted to do. I used to do large scale illusions and stage magic.. but I have since sold all my illusions and I have been moving torwards cards and coins and other general close-up magic.
I was once fairly skilled withe coin boxes... but I am now very rusty.
Anyways.... After getting what I wanted to use, I found that most of what I had for coins, in terms of shells and folding coins... etc... were all regular US half dollars. I know that magicians (at least in the US) seem to prefer silver half dollars. This raises the question of whether I should put away my regular expanded halves and such and move to silver. I have some silver coins... but I wasn't sure if there was a specific type of silver half dollar that was preferred? (year and type and such?)... also how aailable are silver expanded shells and silver folding coins... and the like... the expanded shell is really the most important... I don't use the folding coin except for an interesting rendition of the coin in bottle in which the label eventually turns itself inside out as well.
Anyways... any information would be appreciated. I primarily like working with silver half dollars (which I have used before in the coin boxes) and "english pennies" (are they really pennies? They're awfully large!

Also besides the coin boxes... what else makes a good basis for coin magic? I'm trying to move away from gimmicks and more towards sleight of hand.... so expanded shells and coin boxes will both be helpful... but what else? I am not so interested in one-trick-wonders like cigarette through coin... there was a time during which I loved those tricks... but no longer.
Anyways... I'm rambling... thanks.
