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 five-ounce format (abbreviated as 5 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 marks the 450th Anniversary of the birth of William Shakespeare.
The mint says about this coin:
One of the greatest writers in the English language, William Shakespeare, is immortalised on this spectacular 5oz silver proof coin. Celebrating the 450 years since the birth of this famous playwright, The Perth Mint is delighted to present a stunning commemorative befitting Shakespeare and his literary achievements. |
