The first egg commissioned by Tsar Alexander cost approximately 4200 rubles. At that time, it was a huge amount, because even a well-earning government official or general could not afford such a trinket for an annual salary (an agricultural worker earned little more than a ruble a day).
The most expensive egg made for Tsar Nicholas II cost over 20.000 rubles.
Currently, the prices of Fabergé eggs are exorbitantly high, some of them are valued at $30-50 million. The most valuable is the coronation egg, whose value is estimated at $100 million.
