An assayer separates metals or other components from dross materials by solution, flotation, or other liquid processes, or by dry methods, such as application of heat to form slags of lead, borax, and other impurities. Residues may be weighed on a balance to determine any proportion of precious metals or other components. Specialists in testing and analyzing precious metals are designated gold-and-silver assayer.
"Assayer" means a person who analyzes metals, ores, minerals, or alloys in order to ascertain the quantity of gold or silver or any other substance present in them.

Without a doubt, one of the greatest mysteries of modern Spanish numismatics is the absence of the assayer's mark on all of the coins that King Philip II struck from his silver ingots (1) at his own private water powered mill mint in Segovia, Spain.
The inclusion of the assayer's mark on all Spanish coinage, obligatory since 1497 (4) was a direct response for the need to identify the individual who prepared the alloy, whom, for his part, guaranteed that the fineness corresponded to the officially required 11 dineros and 4 grains, in the case of silver coins.
The absence of the assayer mark on all of the silver coins struck at the Segovia Mill Mint during the reign of King Philip II has always been one of the biggest mysteries of modern Spanish coinage and was always worthy of a detailed numismatic investigation.
