5 Dollars Edmontosaurus

Sierra Leone has issued collector-oriented wildlife and prehistoric series continuously since the early 2000s, contracting production through external mints — this piece almost certainly struck by B.H. Mayer or a comparable European facility rather than anything on African soil. The Edmontosaurus, a hadrosaur whose remains are among the most abundantly recovered of any large dinosaur, was first formally described by Othniel Charles Marsh in 1892 from material excavated in the Dakota badlands.

Sierra Leone holds no geographic or paleontological connection to the subject matter.
