The New Zealand post office has released some really nice collectables.

This is one of my favourites:
The Bag End coin with its unique wooden door is an innovative addition to 'The Hobbit: The Battle of the Five Armies' coin issue. The door, made from a piece of wood from the Hobbiton Movie Set party tree, is incorporated into the coin, meaning you can get your very own Middle-earth keepsake. Pre-order yours for late November.
Highlights:
- Incorporates a piece of wood from the party tree from the Hobbiton Movie Set – you can get your very own piece of Middle-earth
- Comes in specially designed container that resembles the door to Bag End
- Minted from 0.999 silver
- Worldwide mintage of 10,000
- Words ‘Middle-earth – New Zealand’ inscribed on the rim
- Individually numberedcertificate
