Dwight N. Manley (born February 23, 1966) is an American businessman, Managing Partner of California Gold Marketing Group LLC, numismatist, professional sports agent, and real estate developer from Brea, California.[1]
Manley's interest in numismatics began at the age of six when he received a 1909 Lincoln cent. His passion for coin collecting was further nurtured through the American Numismatic Association's (ANA) popular Summer Seminar which he attended in 1981 thanks to a scholarship he won, which was encouraged by the ANA and its governor.[2]
In 2001, Manley funded a multi-million-dollar renovation of the American Numismatic Association's (ANA) museum and library. The library more than doubled its shelf space and expanded its climate-controlled rare book room.[2]
In 2007, Manley donated a copy of Illustrium Imagines, the world's first illustrated numismatic book printed in 1517, to the ANA.[3] As Managing Partner of California Gold Marketing Group LLC,[4][5] Manley undertook negotiations to buy the ship's cargo of historic California Gold Rush-era coins and gold assayers' bars[6][7][8]
Manley funded for "A California Gold Rush History",[9] a 1,000-page book, by selling treasures recovered from the Central America, contributing over $500,000 to research and preparation costs.[2] This donation also included other significant Washington-related medals Manley had acquired separately totalling over 1,000 coins and medals.[10]
In 2022, Manley donated more than 60 books, auction catalogs, and photographs that he acquired at auction from the Sydney F. Martin Numismatic Library Collection.[3] All items were previously owned or annotated by the noted numismatic researcher and author Walter Breen (1928-1993), with many containing Breen's handwritten notes.[11]
Beyond numismatics, Manley is the president of United Sports Agency.[12][2] In June 2006, he was appointed as the national manager of the Jockeys' Guild,[13][14][15] a position he voluntarily served without compensation for a period of one year.[16][2]
As a sports agent, Manley also represented all-star Karl Malone of the Utah Jazz[1] and negotiated a $66.5 million contract for the player.[17] Manley was also known in the sports world for his role as the agent of NBA player Dennis Rodman during the 1990s.[18][19]
In addition to his roles in sports management, Manley is a television producer.[2][20]
