Based on current list of items from delivery tasks that we have here:

Which ones are the hardest and rarest?
For example: Night Harpy items are rare because only a few players are hunting them, it's a new hunt, so their feathers are rare and don't have too much availability on the market, as well because their respawn is random and don't occur every night, it can pass a whole day without respawning. So for me, this is a "rare" item occasion which I need to try to buy them before they show up at my delivery task list if I'm willing to do all deliveries every week.
So based on that, which other items of that list is hard to obtain (rare to drop) and/or creatures are not hunted that often, leading to the items not having too much availability on the market?
