Golden ticket
From Jenny Everywhere Wiki
As part of her work for the Multidimensional Finders Service, Jenny Over-There once helped a “kid” find a golden ticket. (PROSE: The Tribulations of Jenny Over-There)
Behind the scenes
Golden tickets were involved in the plot of Roald Dahl's Charlie and the Chocolate Factory, where a small number of such tickets were spread around the world by Willy Wonka, allowing whatever child found them to take part in a tour of the titular magical Chocolate Factory.
