As explained earlier, the Aachen and Nuremberg sets of Imperial Regalia were allowed to leave their respective cities only if they were needed for a coronation. Because of that, the Emperors used to commission crowns for their personal use.
From these, only a few survived to our days: The crown of Rudolf II (see Austrian Crown Jewels) and two Wittelsbach crowns, made for Charles VII Wittelsbach in 1742. Other early pieces of insignia also exist.
1. Posthumous portrait of Emperor Sigismund by Albrecht Dürer - c. 1509, Germanisches Nationalmuseum (Nuremberg)
2. Portrait of Emperor Frederick III Habsburg by Hans Burgkmair - c. 1500 after a lost original from 1468, Kunsthistorisches Museum (Vienna)
3. Portrait of Maximilian I Habsburg by Bernhard Strigel - c. 1508, Tyrolean State Museum Ferdinandeum (Innsbruck)
4. Portrait of Charles V Habsburgas Ruler of vast realms by Peter Paul Rubens - 1604, Residenzgalerie (Salzburg)
5, 6. The crowns of Charles VII Wittelsbach, Emperor and nothing, made after his election in 1742. While the Habsburg dinasty had the personal crowns of previous kings, Charles didn’t have any of his own, and so he commissioned two different crowns to be made in Frankfurt am Main and Augsburg. They are kept at the Residenz in Munich.
Also not a part of the Austrian collection at Hofburg are;
7. The crown of Otto III, kept at Essen Cathedral.
8. The crown of Empress Constance, part of the treasury of Palermo Cathedral
9, 10. The crown of Henry II Wittelsbach (1270) and Empress Kunigunde, on display at the treasury of the Residenz in Munich. Other items in the collection are a crown from Bamberg and the crown of Blanche of Lancaster, Electress Palatine.
