In 1897, the Federal Council decided to set up a Swiss airship company, ten years after military airships had become established in Europe. Before that, pioneers like Eduard Spelterini and the Piccard brothers had made the first balloon test flights for the army. With the outbreak of the First World War and the development of modern air forces, the importance of balloons waned; in 1937, the balloon corps was dissolved.<\/p>\n<p>The series begins with the 20-franc coin \u201cPioneers of Swiss aviation\u201d, which shows the early days when hot-air ballons first started to conquer the skies.<\/p>\n<p>The obverse shows hot-air balloons with different shapes and baskets, tracing the technical developments of the time. But these illustrations show not only technological advances, but also the passion of early Swiss aviation pioneers. The balloons rise into the air against the backdrop of the Saanenland and the Swiss mountains Gummfluh, La Videmanette and R\u00fceblihorn. The obverse also carries the inscription in German \u201cPioniere der Schweizer Luftfahrt\u201d. A propeller blade adorns the reverse, depicting advances in technology up to the present day. It bears the inscription \u201cCONFOEDERATIO HELVETICA 2025\u201d around the edge. The design is completed by the nominal value of 20 francs and the letter \u201cB\u201d for Bern.<\/p>\n<p>The special coin \u201cPioneers of Swiss aviation\u201d is made of silver and weighs 20g. The coin is issued in a mintage of 3\u2019500 pieces in the quality \u201cProof\u201d in presentation case and 7\u2019500 pieces uncirculated in the blister.<\/p>\n<\/div>[vc_row_inner][vc_column_inner width=&#8221;2\/3&#8243;]<div class=\"section__text section__text--center intro-animation intro-animation--bottom\"><p>Legal face value: CHF 20<br \/>\nAlloy: Silver 999<br \/>\nDiameter: 33 mm<br \/>\nWeight: 20 g<br \/>\nDate of issue: 18.09.2025<\/p>\n<p><strong>Mintage<\/strong><br \/>\nProof in presentation case: 3,500 units<br \/>\nUncirculated: 7,500 units<\/p>\n<p><strong>Prices<\/strong><br \/>\nProof in presentation case: CHF 79.-<br \/>\nUncirculated: CHF 25.-<\/p>\n<\/div>[\/vc_column_inner][vc_column_inner width=&#8221;1\/3&#8243;]<div class=\"section__image section__image--center intro-animation intro-animation--bottom\"><div class=\"picture_container\" style=\"width: 160px\"><picture><source media=\"(min-width: 768px)\" srcset=\"https:\/\/www.sondermuenze.ch\/wp-content\/uploads\/swissmint-luftfahrt-20fr-bs-620x620px.png\"><source media=\"(max-width: 767.98px)\" srcset=\"https:\/\/www.sondermuenze.ch\/wp-content\/uploads\/swissmint-luftfahrt-20fr-bs-620x620px.png\"><img decoding=\"async\" src=\"https:\/\/www.sondermuenze.ch\/wp-content\/uploads\/swissmint-luftfahrt-20fr-bs-620x620px.png\" alt=\"Silver coin Pioneers of Swiss aviation\" width=\"620\" height=\"620\" \/><\/picture><\/div><\/div><div class=\"section__image section__image--center intro-animation intro-animation--bottom\"><div class=\"picture_container\" style=\"width: 160px\"><picture><source media=\"(min-width: 768px)\" srcset=\"https:\/\/www.sondermuenze.ch\/wp-content\/uploads\/swissmint-luftfahrt-20fr-ws-620x620px.png\"><source media=\"(max-width: 767.98px)\" srcset=\"https:\/\/www.sondermuenze.ch\/wp-content\/uploads\/swissmint-luftfahrt-20fr-ws-620x620px.png\"><img decoding=\"async\" src=\"https:\/\/www.sondermuenze.ch\/wp-content\/uploads\/swissmint-luftfahrt-20fr-ws-620x620px.png\" alt=\"Silver coin Pioneers of Swiss aviation\" width=\"620\" height=\"620\" \/><\/picture><\/div><\/div>[\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/div>","protected":false},"excerpt":{"rendered":"[vc_row][vc_column][vc_row_inner][vc_column_inner width=&#8221;2\/3&#8243;][\/vc_column_inner][vc_column_inner width=&#8221;1\/3&#8243;][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]","protected":false},"author":3,"featured_media":0,"parent":0,"menu_order":88,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-9772","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.sondermuenze.ch\/en\/wp-json\/wp\/v2\/pages\/9772","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sondermuenze.ch\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.sondermuenze.ch\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.sondermuenze.ch\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sondermuenze.ch\/en\/wp-json\/wp\/v2\/comments?post=9772"}],"version-history":[{"count":1,"href":"https:\/\/www.sondermuenze.ch\/en\/wp-json\/wp\/v2\/pages\/9772\/revisions"}],"predecessor-version":[{"id":9775,"href":"https:\/\/www.sondermuenze.ch\/en\/wp-json\/wp\/v2\/pages\/9772\/revisions\/9775"}],"wp:attachment":[{"href":"https:\/\/www.sondermuenze.ch\/en\/wp-json\/wp\/v2\/media?parent=9772"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
