Containing objects within another via rigid and collider

Hi there,

I have made a raffle barrel, and i'd like to put some tokens inside that I will animate getting pulled out.
I only have Cinema 4d broadcast, and so I can only do dynamics inside a mograph object.

So i'm using a mograph cloner to create 6 tokens.

When i spin the barrel, the tokens do interact with the barrel and bounce around inside, but some of them go flying out of it? The faster I spin the barrel, the quicker majority of them fly out.

Is there some settings that allows them to get past a collider object?
