A very nice Prussian guilder from the late 17th century.
A variety with a wide bust.
Very well preserved luster, especially on the reverse.
Obverse: bust in antique armor, to the right, in the rim the legend:
FRIDER-III-D-G-M-B-S-R-I-ARC & EL-;
Reverse: under the duke's mitre a ten-field shield of arms, on its sides the initials LC-S, in the rim a legend punctuated by the denomination marking 2/3:
COIN NOVA-BRANDENB-1691*.
