A coin from The Middle Ages, The Augustale (or Agostaro), was a Gold coin introduced by Holy Roman Emperor Frederick II in 1231. It was also adopted by Charles of Anjou in 1278 (in a slightly different form). It weighed 5.25 grams. It contained 4.48 ounces of pure Gold. The Augustale remained in common usage in Sicily until the early 14th Century.
