2018 Austrian Mint Anthropocene 25 Euro Silver Niobium Coin

Legal tender in Austria, the 2018 Anthropocene Silver-Niobium 25 Euro coin measures 34.00 mm in diameter and weighs 16.50 grams in total. The outer ring consists of 90% pure silver while the center disc is composed of primarily niobium, a soft, ductile metal when pure that is hardened by impurities.

Perhaps most noticeable on this coin, the 16th entry in the Austrian Mint’s Silver-Niobium bimetallic coin series, is the skillful artistic use of color on the niobium inner core. Over the past decade and more, the Austrians have developed to masterful levels not only the series but also the technical expertise required to produce such varieties of tone in the niobium alloy.
