In 1654, Queen Christina abdicated and moved to Rome, taking with her an immense coin collection of more than 15,000 coins, some of which she hadinherited. She patronized a group of prominent numismatists of the time, and when she died, she bequethed more than 6000 coins to the Odescalchifamily, and these coins were later sold to Pope Pius VI for the Vatican's coin cabinet. Her coins are easily identifiable by the crowned Cstamped on them, and are some of the oldest and most prestigiously pedigreed coins.
