Does anyone else harvest the magnets and platters from old drives as a monument to selfhosting history?

What are they made of anyways?? Could one see any etching marks with a microscope?
Usually aluminium or glass. There's a metallic coating applied to the outside surfaces that stores the data. That layer is very thin though, so most of the material is the substrate.
They aren't etched
Bunch of tiny magnets either north or south.
