<strong>Obv: </strong>A motif consisting of three fluted columns surmounted by an entablature. The words PEACE, UNION, and LAWS are expressed on the capitals of columns, and the motto "WE the PEOPLE: is present on the entablature. The dates 1787 and 1987 are in the left and right fields respectively. The base of the central motif is the word constitution, and in exergue is the word LIBERTY. <strong>Rev:</strong> The separate motifs in individual panels. In the left panel are two ears of grain with the radiant sun above. The central panel features an eagle with spread wings holding an olive branch and arrows. The right panel depicts an oak sprig with a constellation of stars. Above the design panel is the legend UNITED STATES OF AMERICA. Below is the motto E PLURIBUS UNUM and the denomination HALF EAGLE. An intriguing specimen offering pearlescent slate-gray surfaces with a subtly striated texture. The hardness of the tungsten alloy proved difficult to strike and all (Pollock-5465) examples feature somewhat bolder central elements that fade into obscurity at the peripheries. Issued by Frank Zinkann of Montgomery, Illinois, these "patterns" were to serve as proposals for the upcoming 1987 Constitution Bicentennial $5. Specimens were struck in gold, hafnium, silver and tungsten, and one of the silver examples is available in the preceding lot.,,,
