The cover picture shows a rare, 80% silver, round Australian 50‐cent piece, which was introduced in 1966 when Australia changed currency from the Australian pound to the Australian dollar. It was later replaced with a copper/nickel dodecagonal (12‐sided) version in 1969. The coin underpins the reaction of a silver(I) acetylide with adamantyl iodide affording the bridgehead‐substituted adamantylacetylene. This new methodology has nanotechnological ramifications as discussed in the article by C. M. Williams et al. on p. 241 ff. Brett D. Schwartz is acknowledged for preparing the artwork for the cover picture.
