Issued on January 23, this is the 11th coin in the silver niobium series and highlights Austria’s long and influential contribution to tunnel construction.

The ‘New Austrian Tunnelling Method’, which uses the geographical stress of surrounding rock to strengthen a tunnel, was developed from 1957 to 1965 and has since done a great deal to revolutionize tunnel construction around the world.

The coin features a present-day tunnel boring machine positioned within the ice blue niobium core. The outer silver ring shows the mountains that this engineering wonder cuts through. The reverse design shows a road tunnel within Austria’s alpine landscape. The silver ring contains an image of a worker using a drill to loosen rock. The word “Tunnelbau” (tunnel construction) appears at the base.
