What is the covering on the "thing"?

It looks like a magnetic stirrer bar which would be placed in a container of liquid and rotated by the application of a rotating magnetic field either from a motor or an set of electronically controlled coils. If it is, the covering will be PTFE or glass.

Very common in laboratories.

Value? a few pence to a pound.

It is a hard metallic coating, or it is metal itself.

A mini capsule with an alien inside transported down to earth by lightning and planted in the ground ready to grow three tripod legs and take over the world, and destroy Tom Cruise in the process. :o)
