1 Dollar Green Monkey

The green monkey (Chlorocebus sabaeus) was introduced to Barbados from West Africa during the slave trade era, likely arriving aboard ships transporting captives from Senegal and Gambia in the 17th century. With no natural predators on the island, the population expanded dramatically — so much so that Barbadian farmers have long regarded them as agricultural pests, and culling programs have operated intermittently for decades. The coin's subject is simultaneously an invasive species and an unofficial national animal.
