Each of these 2018 issues is struck from yellow-colored titanium and are incredibly rare with a maximum allowed mintage of just 7,500! Each of these stunning titanium pieces have an obverse design that displays the iconic Yellow Tree Frog sitting atop some leaves within its natural environment. The reverse of this titanium piece features the Fiji coat of arms: a heraldic design featuring a Shield with the cross of St. George, flanked by Fijian warriors, with a canoe above the shield. As Titanium responds in a different way with every strike, each Yellow Tree Frog coin is technically unique and differs a little in color to the next. There is likewise a lined result that exists on the coins which is distinct to this particular metal.
