Ascension Island, an isolated volcanic island between the coast of Africa and Brazil, presents this fascinating titanium coin. Titanium is a strong metal and is rarely used for coinage as specialized minting equipment is needed. One advantage of the material is that its color can be manipulated. Honored in a rich purple hue on this one crown coin is the majestic Queen Triggerfish. A reef dwelling fish found in the Atlantic Ocean, the large oval-shaped creature has unique spines which lock it into a crevice for protection. The Queen Triggerfish also has special membranes which are used to produce an audible sound which warns other fish to stay away.
