Desiring a beautiful coin to sell, Palmer asked artist
Kenyon Cox to produce sketches. She was, however, determined to have a woman actually design the coin. She also consulted with Sara Hallowell, who was both the secretary to the fair's Director of Fine Arts and was helping the Palmers amass a major art collection. Hallowell contacted sculptor
Augustus Saint-Gaudens, who recommended his onetime student, Caroline Peddle, who was already engaged in exposition work, having been commissioned by
Tiffany's to produce an exhibit. Palmer agreed to have Peddle do the work. After Congress authorized the souvenir quarter, the
Director of the Bureau of the Mint,
Edward O. Leech, wrote to Palmer on March 14, 1893. Although he expressed a willingness to have the Lady Managers select the design, Mint Chief Engraver
Charles E. Barber and
Philadelphia Mint Superintendent
Oliver Bosbyshell had already urged Leech to keep the design process in-house at the Mint. Palmer replied that the Lady Managers had decided that the quarter would bear a portrait of
Isabella I,
Queen of Castile (in Spain), whose assistance had helped pay for Columbus's expedition. Palmer indicated that she was consulting artists and suggested that the Mint submit a design for consideration. She also met with Illinois Congressman
Allen Durborow, chairman of the House of Representatives' Fair Committee and a former colleague of Secretary of the Treasury
John G. Carlisle, Leech's superior. Palmer suggested to the congressman that he advocate for the Lady Managers with Carlisle and Leech. Palmer, by letter, hired Peddle to do the design work in late March. She instructed the artist that the coin was to have a figure of Isabella on the obverse, and the inscription "Commemorative coin issued for the Board of Lady Managers of the World's Columbian Exposition by Act of Congress, 1492–1892" on the reverse, as well as the denomination and the name of the country. The chairwoman did not request that Peddle provide the Lady Managers with the design before sending it to the Mint. Palmer informed Carlisle and Leech of her instructions. Carlisle had no objection to a coin being designed by a woman, or to the use of Isabella's head. The secretary told Palmer that the reverse, with its long inscription, would appear like a business advertising token, and he asked that it be revised. Leech sent a note to Superintendent Bosbyshell informing him that the Lady Managers would likely have an outside sculptor create the obverse and asking him to have Mint Chief Engraver Charles E. Barber create some designs for the reverse for possible use. Obedient to Palmer's instructions, Peddle sent Leech sketches of a seated Isabella, with the long inscription on the reverse; she hoped the Mint Director would allow her to shorten it. Leech was unhappy with the reverse, and decided that Barber would design that side of the coin. Barber and Bosbyshell wrote to Leech that Isabella's legs would appear distorted if the seated figure were used and advocated a head in profile. Carlisle agreed, stating that he had only given permission for a head of Isabella. Peddle was informed that Barber would produce the reverse, though the design would be sent to her for approval, and she would have to change her obverse. Meanwhile, Palmer was growing increasingly anxious: with a timeline of two months from design approval to the availability of the actual coins, she feared that the pieces would not be available for sale until well into the fair's May to October run. Under pressure from all sides, Peddle threatened to quit the project, writing that she "could not consent to do half of a piece of work". What finally wore down Peddle's patience were two letters dated April 7. One, from Leech, asserted his right as Mint director to prescribe coin designs, and told Peddle that the obverse would be a head of Isabella, while the reverse would be based on sketches by a Mint engraver which she would be free to model. The second, from Bosbyshell, imposed the additional requirement that Isabella not wear a crown, which he deemed inappropriate on an American coin. On April 8, 1893, Caroline Peddle withdrew from the project. Following Peddle's resignation, Leech wrote a conciliatory letter to Palmer, who responded regretting that the three of them had not worked together, rather than at cross-purposes. Palmer had written to suggest an alternative to the inscription reverse: that the coin depict the Women's Building at the fair. Barber prepared sketches and rejected the idea, stating that the building would appear a mere streak on the coin in the required low relief. Instead, he favored a sketch prepared by Assistant Engraver
George T. Morgan, showing a kneeling woman spinning flax, with a
distaff in her hands. Leech was not fully satisfied with the proposal, stating that the juxtaposition of Isabella on the obverse and the Morgan reverse was "too much woman". Before accepting Morgan's design, Leech wanted Barber to produce some reverses himself, which the chief engraver did, and Bosbyshell forwarded them to Leech on April 11 and 12. These showed various uses of a
heraldic eagle. After considering these efforts, Leech decided on Morgan's design and wrote to Palmer accordingly, stating that "the distaff is used in art to symbolize patient industry, and especially the industry of women." In response, the Lady Managers suggested the use of the building's portal, and asked if it was possible to place a living person on the coin. Leech stated that Secretary Carlisle had selected the distaff reverse, and his determination was binding. Bosbyshell informed Leech by letter that Stewart Cullin, curator at the
University of Pennsylvania, possessed a number of medals depicting Isabella, and former general
Oliver O. Howard was engaged in writing a biography of the late queen and possessed likenesses of her. Leech agreed that these men be consulted. Carlisle was reluctant to allow an inscription which made distinctions by sex, such as "Board of Lady Managers", to appear on the coin, but he eventually agreed to that wording. On April 24, the Mint Director sent Palmer a box containing two plaster models of the obverse, one of Isabella as a young queen, the other showing her more mature. He also informed her that distaff reverse would be used, with the wording agreed to by Carlisle. The obverse models were supposedly made by Barber based on an engraving of Isabella forwarded by Peddle to the Mint at Palmer's request, but Moran suggests that the period of only a day between receipt of the engraving and completion of the models (during which Barber also attended the funeral of Bosbyshell's grandson) means that Barber was working on them before that. The Board of Lady Managers on May 5 selected the young queen. == Design and reception ==
