Germany
Germany has no assay office — a maker may leave a piece unmarked, but if purity is declared it must use the national stamps: an imperial crown with a crescent moon, or a sun.

Voluntary marking
The Feingehaltsgesetz of 1884 (effective 1888) unified the German states on a thousandths system with two imperial emblems, replacing the old city marks and the Loth system.
No assay office. Marking optional; the stamp design is fixed once used.
