Kennedy royal Anthony Shriver and his wife, Alina, have sliced $1 million off the price of their Miami Beach Mediterranean-style mansion, now asking $9.8 million.

Shriver, who heads the nonprofit Best Buddies, is the son of Eunice Shriver (founder of the Special Olympics and President John F. Kennedy’s sister) and Sargent Shriver (who founded the Peace Corps). His sister is broadcast journalist Maria Shriver, ex-wife of ex-California governor Arnold Schwarzenegger.

The seven-bedroom, five-and-a-half-bathroom waterfront home measures 6,822 square feet. Sitting on more than half an acre on Pine Tree Drive in La Gorce, the property features a pool as well as a private dock with a boat lift on the canal and oceanfront access. The listing broker is Esther Percal of Berkshire Hathaway HomeServices EWM Realty.
