We got self made halloween 2013 crates for TF2 a few days ago. But you can't open them. I think it was because the self made keys for halloween became regular self made keys after the holidays. This way people can see what crate your item was in.
I can see the ember chest and earth chest but I can't see the halloween chest in there. I can also see: Treasure of Heroic Bounty Locked Gemstone Cache
There's 3 item chests. Ember Chest, Earth Chest, and Halloween Chest. The other 2 chest items are for crafting scrolls and gems for socketing I think. Here's where you can see what got in. http://tf2b.com/updates/d2t
