Chicago trading card magnate Matthew Bayer and his wife, Joyce, who are the mystery buyers who paid $14.25 million in 2024 for a seven-bedroom, 15,000-square-foot Lincoln Park mansion, are trying to sell their penthouse condominium on the 46th floor of Streeterville’s One Magnificent Mile building.
Features in the six-bedroom, 9,000-square-foot condo, which was redesigned by Wheeler Kearns Architects, include eight full bathrooms, three half bathrooms and 7-inch-wide-plank European white oak floors. The condo also has Grigio Piesantina limestone, Crestron lighting, a “sculptural staircase,” floor-to-ceiling windows, a great room with a custom burl wood wet bar and a glass wine room, a private terrace off the great room and a Valcucine kitchen with Sub-Zero and Miele appliance, according to listing information. Other features include a primary suite with a sitting area and two custom walk-in closets, and a second-level private wellness and entertainment sanctuary that contains a sunroom with a marble-clad wet bar.
Listing agents Ryan Preuett and Tim Salm did not respond to requests for comment.
Bayer and his wife first listed the condo for $5.995 million in September. They cut their asking price to $5.5 million in January.
The couple assembled the duplex in stages between 2010 and 2014. It has homeowners association dues of $12,081 a month.
The couple’s identity as the buyers of the $14.25 million Lincoln Park mansion in 2024 has not been revealed publicly until now.
