The vast majority are in state museums. 54 imperial eggs are known (42 have been preserved to this day), the rest are known from descriptions, accounts, and old photographs, and these eggs are believed to have been lost.
One of them may have left Russia in 1918 with the rightful owner in the luggage of Empress Maria Feodorovna, who left via Crimea for Denmark.
Most of them disappeared in the revolutionary confusion, and those that remained, along with other tsarist jewels, were transported to Moscow to the Kremlin. They remained there until 1930, when, in search of funds, 14 of them were sold on Stalin's orders (supposedly some for less than $400). Most of them were acquired by the American entrepreneur Armand Hammer and the Englishman Emanuel Snowman.
