I was under the impression that the mainstream opinion is that there was
never a planet in the asteroid belt - that Jovian perturbations
increased the relative velocities of bodies in that region so that
collisions didn't result in accretion, and also ejected most of the mass
from that region before a planet could form.
Metallic asteroids/meteorites formed in a parent body large and hot
enough to differentiate metals by melting and gravitation. Whatever the
current conditions, at least two larger bodies existed in that area.
They no longer exist, except as fragments.
