  • "At a time when other monarchs--or their minters--watered down coins to make them stretch further, the vast output of the Schwaz mine allowed Sigmund to mint a silver coin of unsurpassed purity. The coin featured an image of him holding a scepter and wearing a jaunty, oversized crown. The coins were a hit and earned him the name Signmund Rich in Coins. When a merchant received one of Sigmund's silver guldiners, he knew he could trust it. The popularity of the coin--weighing the same as six quarters--attracted imitators across Europe, including the German city of Joachimsthal. Joachimsthal introduced a coin of identical size and silver content, and called it the thaler. The Danes called their version the dollar. Three centuries later, Americans gave a nod to the Danes and ran with it. Sigmund loved his guldiners and Fugger gave him bags of the coins as gifts."
