What are the 10 best Assassin's Creed collectible items?

[MortalMonday]

Curios to know what everyone's top 10 AC items (more than 10 is fine too, I guess) are; #1 being the absolute very best of the best.

You don't have to own them necessarily. You just have to give your opinion on what the greatest pieces are. Whether it be rarity, beauty, or some other attribute; give your list of the top 10 AC items in existence!

I'll form my own list later, or maybe we can all work together to come to a mutually agreed upon/consensus list; The CE.org master list of the greatest AC items in existence.
