On 29 October 2015, the Lithuanian Sea Museum opened the exhibition “The Sea Opens up the World” in the Exhibition and Education Hall at the Money Museum. It puts on display nearly 100 commemorative coins and medals on the theme of geographical discoveries, explorers, and types of vessels. This thematic collection was compiled by the collector Feliksas Rimkevičius (1939–2010), who worked for a long time as a pilot at the port of Klaipėda. Most of the exhibited coins were issued in the 20th century in Portugal, Somalia, the United Kingdom, Russia, Poland, Korea, Cuba, and Germany. They depict plots related to historical events, vessels, and individuals. Visitors of the Exhibition will be able to dive into the world of maritime history, full of romanticism and adventures: they will get acquainted with the Norman traveller Leif Erikson, who, at the very beginning of the 11th century (circa 1000–1001), landed on the eastern shore of present coastal North America and established the Vinland settlement; by going back several centuries, discover America together with Christopher Columbus; get to know the world of Asia with Marco Polo; wander oceans with James Cook; conquer the North with Roald Amundsen. Navigation devices will help travel through time and seas; without them, there would not have been the following discoveries: Jacob’s staff, which was used in the 14th–17th c. to determine a vessel’s latitude from the angle between the sun or Polaris and the horizon; sextant — a navigation instrument used to measure the angle between any two visible objects, and the Traverse Table, which gave the difference of latitude and departure corresponding to any given course and distance made by a vessel over a period of time. There are also two stands with the Money Museum’s exhibits (coins and their plaster models) dedicated to the city of Klaipėda and the London Olympic Games 2012.
