were not recorded, the House Coinage Committee issued a memorandum stating that "the new design would replace the present type of quarter dollar", was on "a popular denomination" and "would replace an unsatisfactory design now being issued". Congress passed the act on March 4, 1931, and the new Washington quarter began to be struck in 1932, ending the Standing Liberty series. Nevertheless, many Standing Liberty quarters remained in circulation until silver coins began to be hoarded by the public in 1964, prompting the change to base-metal pieces. The United States Mint in 2015 announced plans to restrike for collectors, in gold, the three silver coins first issued in 1916. The quarter would have its weight and fineness inscribed on the obverse, and thus would technically be a bullion coin. The quarter was to be the original 1916, with the bared breast. No more than 100,000 were minted at the West Point Mint (mint mark "W" is in the same location as all other coins of this type).
