Atlantium minted coins, though the levels of Atlantian economic activity remained low. The first coin was the 20th anniversary 10 solidi coin, which has a likeness of George Cruickshank as the obverse and the imperial eagle as the reverse. In 2011, a 30 solidi coin was issued to commemorate the 30th anniversary of Atlantium. The coin had the likeness of George Cruickshank on the obverse and the wedge-tailed eagle ("Aquila audax") on the reverse and was struck in cupronickel and plated with 9 carat gold. Banknotes of Atlantium were denominated in imperial solidi (10, 25, 50 and 100 imperial solidi) and are currently divided into a 2006 series and a 2007 series.
