The Tuvaluan Dollar is the currency of Tuvalu - a small nation in the Pacific Ocean. Tuvalu has never had banknotes of its own, and has been issuing coins since 1976; these circulate together with coins of the Australian Dollar, which is also legal tender in the country, and to which the Tuvaluan Dollar is pegged.
The Australian Perth Mint issues a large variety of non-circulating legal tender coins under the authority of Tuvalu. Some of these are in the half ounce silver format (abbreviated as 1/2 oz). Strictly speaking, they are not bullion as they are priced at a premium and are targeted at collectors who appreciate them for their artistic merit and collectable value and not just for their precious metal content.
This coin is part of the long-running James Bond coin series by the Perth Mint, and features the movie Skyfall.
The Mint says about it:
The 23rd of 25 1/2oz silver coins designed for fans of James Bond, this officially licensed product celebrates Skyfall, the 2012 action-adventure starring Daniel Craig in his third appearance as 007.
Created by former intelligence officer and author Ian Fleming in 1953, James Bond is a fearless, charismatic and deadly British Secret Service agent with a "licence to kill". Also known by the code name 007, he has been portrayed by six actors - Sean Connery, George Lazenby, Roger Moore, Timothy Dalton, Pierce Brosnan and Daniel Craig - in 25 thrilling movies released by EON Productions since 1962.
In Skyfall, 007’s failure to retrieve a revealing hard drive stolen from MI6 results in an unprecedented attack on the intelligence agency’s London HQ. Bond discovers that former agent turned cyber terrorist Raoul Silva is behind a revenge plot targeting M who abandoned him in order to save six other operatives. |
