Any PM metal ( perhaps Pt ? ) in those boards?

Nope, iron cores, and don't you dare scrap them as they have more historical and collectible value than any PM value.

No PM but a lot of money. I sold a couple of core memory boards on ePay a few years ago and I got between $80 and $150 each. If a computer have core memory then the rest of the machine is probably also quite valuable if it is in good shape.

I have seen some core memories with a gold plated copper foil circuit board on either side of the core plane, presumably for EMF shielding.
