Morgan continued to collect material for his private library until his death in March 1913. His estate was valued at $128 million (about $ billion in ), over half of which lay in the worth of his collection. J. P. Morgan's will bequeathed the art collection to Jack, with the request that Jack make the collection "permanently available for the instruction and pleasure of the American people". The month after J. P. Morgan's death, the New York state legislature granted a two-year exemption enabling Jack to import his father's overseas collection without having to pay import duties. However, Jack Morgan sold off much of the overseas collection rather than importing it. During 1914, the collection was displayed in full at the Metropolitan Museum of Art, the only time the whole collection was displayed. The import duty exemption expired in April 1915, and Jack sold various items in the collection to pay the inheritance taxes and to raise money for the cash bequests in his father's will. The taxes were substantial, totaling $7.5 million in 1916. Frances Morgan, Jack's mother and John Pierpont's widow, continued to live at J. P. Morgan's old residence until her death in November 1924.
