For now, at tonberry atleast, the shard is the most wanted item.

As I want to level up my goldsmith to level 50, (without doing a levemete because I will use the ingot/mats for crafting later), need around 5k - 7k shard. at tonberry, the shard float around 30-35gil for whole week. Expect to jump up 36-40gil for this weekend.
