Coffey has published numerous articles as well as several books and exhibition catalogues reflecting his areas of expertise. He has often engaged in detective work resulting in the recovery and rediscovery of works previously thought to be lost, leading to a reassessment of their value. Examples include the oeuvre of painter
Louis Remy Mignot and a large sculpture entitled “
Saul Under the Influence of the Evil Spirit” by
William Wetmore Story that had disappeared for 150 years. In 2013, well after the Gallery's establishment, he put together an effort to compete with bidders from around the world during an auction of Judaica at Sotheby's that netted the Museum three new pieces. In other roles, Coffey has been the NCMA's liaison with the Friends of the Judaic Art Gallery as well as the statewide director of the
Israel/North Carolina Cultural Exchange between 1994-97. The latter role involved travel to Israel and led to his work on contemporary Israeli painting.
Moshe Kupferman: Between Oblivion and Remembrance was among the results.
The Landscapes of Louis Remy Mignot: A Southern Painter Abroad, co-authored with
Katherine E. Manthorne, garnered national attention. Mignot had been thought of as a minor nineteenth century painter, and his work had been largely lost and forgotten. Manthorne had been studying nineteenth century artists who traveled to South America; Mignot was among them. Coffey, as part of his curatorial activities for the NC Museum of Art, was searching for a Mignot to add to the Museum's collection. Their collaboration ensued; the research and results were supported by grants from
The Henry Luce Foundation, the
National Endowment for the Arts, and the North Carolina Museum of Art Foundation. In 2010 Coffey participated in a study of memorials in the state capital published by the
North Carolina Historical Commission. His assessment of the
Confederate memorials as art was negative, a point cited in 2017 during local and national debates about
Civil War statues resulting in the controversial removal of many of them, including in
Durham, North Carolina. == References ==
