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 silver ounce format (abbreviated as 1 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 coloured 1oz silver proof coin marks the 150th Anniversary of Alice's Adventures in Wonderland.
The Mint says about it:
The Perth Mint is pleased to present a 150th Anniversary of Alice’s Adventures in Wonderland coin celebrating the first publication of the Lewis Carroll classic. Alice’s Adventures in Wonderland was written by English author Charles Lutwidge Dodgson under the pseudonym Lewis Carroll and was first published in 1865. The book was an overwhelming literary and commercial success, and the fantasy world of Wonderland quickly became as much a part of English literature as Shakespeare and Dickens. |
