The Grand Duchy of Avram is a micronation founded in the early 1980s by Tasmanian John Charlton Rudge, who styles himself the "Grand Duke of Avram". The public manifestation of the Duchy was The Royal Bank of Avram which at one time operated from retail premises owned by The Grand Duke of Avram in George Town, Tasmania, and which still issues its own banknotes and coinage and platinum 1 ounce coins. This enterprise was later relocated to Strahan, on Tasmania's west coast. Customers were required to exchange Australian currency for the Avram equivalents in order to obtain the currency. The Bank still operates today.
