An exquisite piece.
The coin appreciated with the second highest NGC grading, among those given so far.
Obverse: the ruler's head to the right, under it the mint mark A, in the rim the legend:
WILHELM DEUTSCHER KAISER KONIG V. PREUSSEN;
Reverse: eagle of the Reich, in the rim legend:
DEUTSCHES REICH 1872 10 MARK;
Definitely a worthy numismat!
