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 "mini-coin" half gram of gold format. The coins 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 mini-coin is part of a long running James Bond-themed series by the Perth Mint, and features the 007 logo.
The Mint says about it:
A superb addition to our official 007 James Bond coin series, this 0.5g pure gold coin would make a prized-gift and valuable keepsake for fans of the world-famous secret agent.
Created by author Ian Fleming in 1953, James Bond was brought to cinema screens for the first time in the 1962 movie Dr. No. More than 50 years later, 007 continues to entertain and excite audiences around the world in one of the longest running and most successful film franchises of all time. The coin’s reverse portrays the instantly recognisable 007 gun logo and the inscription JAMES BOND.
