The Cover Feature shows how coinage metals such as gold, silver, and copper are rapidly dissolved under mild and safe conditions by the ionic liquid 1‐hexyl‐3‐methylimidiazolim dibromoiodide ([C 6 C 1 Im][Br 2 I]), forming metal(I)–dibromo anionic complexes together with molecular iodine, as proven by X‐ray photoelectron spectroscopy, etching experiments, and gas‐phase analysis. Trihalide ionic liquids are shown to be promising candidates for precious‐metal etching and leaching media, and may also open new possibilities for Au(I) catalysis.
