What to do with 1.0 Items?

I understand this post is a bit late-coming, but I finally decided to spend all day (literally) completely cleaning out my retainers and actually doing something with my saved items. I have Beastcoins and other items from 1.0 that I have no idea what to do with. Here they are, along with the quantity of each.

Ixali Willowknot (x6)
Ixali Mapleknot (x1)
Titan Copperpiece (x2)
Bronze Amalj'ok (x11)
Emerald Leaf
Vortex Headdress (x5)
Inferno Taper (x39)

To all the 1.0 players: Yes, I know I didn't do that many things in regards to the beast tribes or primal battles. =P I simply want to know what to do with these items, and I can't seem to google any information about them, other than what worthless amounts of gil they sell for and that they are unique/untradable. I was hoping that maybe there is an NPC who will exchange them for something else for me, but I've about given up hope, heh.

Lol. I still have my Inferno Tapers and Vortex Headdresses, too. As far as I'm aware, there's nothing to do with them.

They are simply relics of a past life.

I will keep the beastmen's currency.... probably some importance in the future... especially with the beastmen dailies allegiance.
