Why this rock is probably not a meteorite:

This one is was found on a beach. The shiny things are metal.

The surface is not smooth like a meteorite and there's no fusion crust. Most importantly, however, the metal blebs are round. That means that they were once molten. Metal blebs in meteorites are never so uniformly round because most ordinary chondrites were never molten. In the ones that did melt (impact melts), the metal blebs are not this large.
What is it?

Possibly a piece of industrial slag. We have been sent a number of pieces of slag that were found on beaches or river shores.
