Obol - Immobilization in the name of Louis

The "immobilized" issues bearing Louis's name were struck by various episcopal and secular mints across the Rhineland and upper Rhine region long after any king named Louis actually reigned — the name became a frozen convention, a mint's shorthand for legitimacy rather than a declaration of current allegiance. By the twelfth and thirteenth centuries, nobody paying a toll or purchasing grain cared which Louis, if any, the legend invoked.
