can you please explain how do you collect this type of currency you are referring to?

Right now, the only way to get them is to trade in old 1.0 gear that had materia melded into them (which is now cracked) to an NPC. Some old 1.0 specific items like hamlet seals and primal "trophies" (inferno totems, kupo nut charms, vortex totems) can also be exchanged.

There is probably another way to get them, just no one knows right now. Perhaps running content at max level. People will find out soon enough.

This is for the allagan runestones, I'm not sure if there is another currency for the AFv2. Didn't look that close when I checked all the NPCs.
