If Lepidoptera on coins is what you are seeking, at Black Mountain Coins we feature several types of butterfly coins. One of the more spectacular coins is the Mexican 100 Pesos coins issued in 1987 in conjunction with the World Wildlife Fund featuring the Monarch Butterfly. The island nations of Vanuatu and Palau have also issued legal tender multicolor butterfly coins and perhaps one of the most imaginative butterfly coins was the 1,000 Central African Francs coin issued in 2011 by the African nation of Cameroon, depicting a 3-D butterfly perched on the surface of the coin, ready to take of in flight.
