If you play the scene you may see them intesect immediately if there are not enough substeps to resolve the collisions.

To me the gaps seem to be very small but distinct. I made them this small so the coins don't have to fall down on each other in the beginning of the simulation. With the collision representation objects it is the same. Am I missing some intersecting meshes here? Or can there be a "too close" to each other?

Make sure you always look at the bullet representation of the collider, not the geo going into the sim.
