What large coins would you recommend for coin magic? I'm wanting to learn Coin One, I know its ambitious for a first coin routine but that's just me

The problem ive always had with coin magic is if they don't use sterling its obvious some sort of gimmick is being used imo. I know this is clearly not the case, you need larger coins so you can see the effect properly and im a bit silly for thinking it.
Half dollars seem to the be coin of choice, anyone ever had their choice of coin questioned?
