If they are worth a fortune I'm sitting on a gold-mine here!
I think I have some old 'Newmarket' (if that was the name) transistors.
Maybe if these kinds of things are now 'historic relics' I should dig

Interesting page for flat cans:

That is an interesting site, takes me back to being an apprentice lad at
RRE. I think that I have an STC "Crystal triode" kicking around somewhere,
