This coin is a one year type issued during the short reign of Frederick as king of Prussia and Emperor of Germany. The old king, William, died in March after a 27 year reign, by which time Frederick was already dying of throat cancer. Frederick died in June and William II succeeded him, to rule until the collapse of the regime in the throes of World War One. 1888 is known as the "Dreikaisersjahr," or "Year of the Three Emperors."  Even so, this type is common and is more obtainable than many issues of William II.
