Palau – Mountains & Flora – Piz Buin – $5 – 2009 – Proof Silver Crown – COA – The sight of a blue gentian, edelweiss or any other typical alpine flower makes many a mountain climber or hiker’s heart leap for joy. Thanks to the high ultraviolet-rays, alpine flowers have an intensive luminous color which is very appealing to our senses. They are survivalists who have adjusted perfectly to their extreme environment, although in many areas the snow melts earlier than in the past due to increased global warming. For this reason, alpine flowers bloom earlier than they used to. Piz Buin is a mountain in the Silvretta range of the Alps on the border between Austria and Switzerland. It forms the border between the Swiss canton of Graubünden and the Austrian state of Vorarlberg and is the highest peak in Vorarlberg. Worldwide mintage on this coin was limited to 2,500 pieces. This beautiful proof silver crown comes as shown with a Certificate of Authenticity.
