The deadline was originally December 14, 1973, but was extended to January 9, 1974 because of the energy crisis and Christmas mail delays. Brooks traveled more than to publicize the competition. By the deadline, the Mint had received 15,000 inquiries and 884 entries. Members of the panel and any person employed by the US government as a sculptor were ineligible to enter. The prize for each of the three winners was $5,000. The judging was originally supposed to take place at West Point; with the delay, it took place instead at the Philadelphia Mint. From the entries, the judges selected twelve semifinalist designs; the sculptor submitting each received a prize of $750. The competitors were to place their work on plaster models, if that had not already been done, and were offered assistance in making the models. The twelve remaining designs were released by the Treasury for public comment in early 1974. Two of the proposed coins featured sailing ships, two featured Independence Hall in Philadelphia, where the Declaration of Independence was signed, and three depicted the moon or lunar spacecraft. Another depicted the Liberty Bell superimposed on an atomic symbol. According to numismatist Michael Marotta in his 2001 article on the Bicentennial coins, "the numismatic community's reaction to the entries was predictable: everyone complained by writing letters to the editor". From the twelve, the judges selected six finalists for review by the National Bicentennial Coin Design Competition Committee, consisting of Brooks, Representative Wright Patman, Senator John Sparkman, Commission of Fine Arts Secretary Charles H. Atherton and Eric P. Newman, chairman of the ARBC's coins and medals advisory committee. After receiving the committee's recommendations, Secretary Shultz selected the winners and on March 6, 1974, Brooks went on the "Today" show to announce them. Jack L. Ahr's design featuring a colonial drummer, with a torch of victory surrounded by thirteen stars (representing the original states) was selected for the quarter. Seth Huntington's image of Independence Hall was selected for the half dollar while Dennis R. Williams' superimposition of the Liberty Bell against the Moon was successful for the dollar. Ahr owned a commercial art firm and Huntington was head artist for Brown and Bigelow, a Minneapolis publishing firm. Williams, at age 21 the youngest person to design a US coin, was an art student who had originally created his design for a class assignment. No change would be made to the obverses of the coins, except for the double dating.
