Magic items certainly have (2), assuming we are talking about a legendary sword or some other durable artifact. I think (1) easily applies, assuming the items is of obvious utility to wealthy nobility, reclusive wizards, or military orders.
Tell that to anyone who wants to sell some uranium fuel rods today.
