2 Dollars - Charles III Barty Crouch

Bartemius "Barty" Crouch Jr. is one of the more psychologically complex villains in the Harry Potter series — a Death Eater who spent years imprisoned in Azkaban by his own father, then secretly held captive under his father's roof before engineering Voldemort's return in Goblet of Fire. Niue has issued legal tender collector coins under licensing agreements with Warner Bros. for over a decade, using its sovereign mint authority to produce silver rounds that circulate almost exclusively among collectors rather than in domestic commerce.
