10 Dollars - Elizabeth II Colosseo

Part of a long-running Cook Islands commemorative program that licensed world monument imagery during the mid-2000s, this issue capitalizes on Cook Islands' status as a sovereign nation in free association with New Zealand — an arrangement that grants it full authority to issue currency while maintaining no realistic circulation for these pieces. The Flavian Amphitheatre, begun under Vespasian around 70 AD and completed under Titus, held its inaugural games in 80 AD with festivities reportedly lasting 100 days.
