as her successor. He was the two month-old son of Prince
and Anna Leopoldovna, the niece of the Empress Anna.

a year for an exchange of new coins at full value. The
"ukaz" stipulated that anyone holding any coins
of Ivan VI after June 1745 would be subject to punishment.
the decree, historians estimate that coins with the value
of about 24,000 rubles were hoarded by the people and never
turned in for exchange.
