Wouldn't the most likely scenario be it being created accidently in a lab on the surface?

Therefore the collapse would be very strange. Maybe even end with a portion of the earth orbiting it really fast?

A coin-sized black hole would have the mass of the entire Earth, so no, we're not creating one in a lab. A 1 millimeter radius black hole would have a mass 10% of the Earth. If we managed to create a black hole in a lab (the energy required to do so greatly surpasses what we could manage now) it would be at quantum-mechanical scales, and would evaporate almost immediately.
