Fabergé Eggs
In the early 20th century, the Bolsheviks of Russia slew the Romanovs, entered the House of Fabergé, and confiscated most of the eggs. They took them to Moscow for safekeeping, but they were ultimately discovered in the 1930s when Armand Hammer, an entrepreneur, purchased ten of them and brought them to the US.
Armand sold some of the eggs, while others remained relatively untouched. The eggs have switched hands so much that there’s no telling who owns them or where they are today. Out of the 50 Fabergé eggs that were made for the imperial family, eight of them are missing. One sold back in 2007 for almost $9 million, so check your attics, basements, and treasure chests for an egg-shaped accessory that serves no purpose.
