The "Washlady" quarter in copper considered today to be one of the most beautiful designs ever made by the US Mint. At that time, however, the design was not well received as, apparently, Liberty's hair and the way it was tied back was considered to be disheveled.
The Washlady name dates back to the April 1891 New York Coin and Stamp auction of the F.W. Doughty collection and was probably given by David Proskey.
This design is R-6 in both silver J1590/P1783 and copper J1591/P1784 as illustrated with between 12 to 15 believed to exist.
The specimen listed in white metal J1592/P1785 is unconfirmed. The Farouk sale coin, which used the white metal coins Adams and Woodin number was described as having been struck in copper in that sale. As the half and dollar are known to exist in white metal, it is likely that the quarter does as well unless that coin is actually J1596/P1786.
