1 Dollar - Elizabeth II USSR Sevastopol

Part of a broader Australian-market commemorative program issued through Tuvalu in the mid-2000s, this coin marks the Siege of Sevastopol — the brutal eleven-month Anglo-French-Ottoman campaign against the city during the Crimean War of 1854–55. Tuvalu's role is purely nominal; the series was produced by the Perth Mint under a longstanding arrangement that uses Tuvalu's issuing authority for collector silver.

The siege effectively ended Russian naval dominance in the Black Sea and forced the demolition of Sevastopol's own fortifications under the terms of the 1856 Treaty of Paris.
