I have a lot of respect for Roth's skill with coins. It is something he will always be far better than me at, and he has been instrumental in the teaching of a huge amount of people. He is a legend in the community and deserves that title.
This performance - This is magic for magicians. He does it very well, but it's basically eye candy with no real meaning. The script is dictating the actions we can see him performing, so it adds nothing. Coins vanish from one place, appear in another. Coins change. Coins change again, and teleport again, and then change again.
He does it very well, as I've said. However, this is not the kind of magic I would want to experience, personally.
