I can guess at why the coil melted down and so much current flowed through the points -
Chances are the coil should have had a resistor or a resistance wire in series from the battery source, so without the resistance to limit the current in the coil windings to a safe value, the heat generated started to cook the insulation off the copper wires inside. The coil has layers of copper wire with thin insulation. If the wire gets too hot the insulation fails and the layers of wire all start to progressively short to each other and what you end up with is nearly a direct short from one coil terminal to the other. Then your battery is effectively connected almost directly to the points and when they close enough current flows to melt wires and get the points hot also. Lucky it didn't catch fire.
