on the dime. Woolley hoped that each sculptor would be successful with one piece. The three sculptors submitted design sketches in mid-February, and on February 23 met with Woolley in New York so the artists could make presentations of the work to him and answer his questions. After discussions between Woolley and McAdoo, Weinman was notified on February 28 that five of his sketches had been selected—for the dime and half dollar, and the reverse of the quarter. The same day, Woolley wrote to MacNeil to tell him he would sculpt the quarter's obverse, and to Polasek to inform him of his lack of success. Members of the Commission persuaded Woolley that so much should not be entrusted to a single artist, and MacNeil was allowed to design both sides of the quarter, subject to the sculptor producing a design satisfactory to Woolley. On March 3, the new coins were publicly announced, with the Treasury noting, "[d]esigns of these coins must be changed by law every 25 years and the present 25 year period ends with 1916." The press release indicated that the Treasury hoped production of the new coins would begin in about two months, once the designs were finalized. The same day, Woolley wrote to Mint Engraver Barber, telling him that his sketches were rejected, and that models from Weinman and MacNeil would arrive at the Philadelphia Mint no later than May 1. According to numismatic historian Walter Breen, Barber became "sullen and totally uncooperative". Lange notes that "numerous delays were encountered as the artists fine-tuned their models while simultaneously avoiding obstacles thrown in their path by Barber. While his observations regarding many aspects of practical coinage were quite accurate, they clearly could have been presented in a more constructive manner." In his book on Mercury dimes, Lange notes that Barber, by then aged 75, had been "compelled over the past ten years to participate in the systematic undoing of a lifetime's achievements"; he had to participate in the process which resulted in coins designed by others replacing ones designed by him. With the new pieces, all American coins would have had a recent change of design (the Morgan dollar was not then being struck). According to a column in The Art World magazine later in 1916, Design The identity of the model for the obverse of the quarter is uncertain. As early as May 1917, the model
