The hardness test (Mohr's scale of hardness) is applicable generally to many solids. BUT not in the case in question when the tungsten is put at the core of a gold coin

or the tungsten is under an appreciable thickness of gold "skin",

or an alloy of gold and tungsten is covered by an appeciable layer of 99.99 fine gold.

BTW, the properties of tungsten are vastly different than gold's, e.g., tungsten is used to make the filaments of electric light bulbs.

BTW, tungsten has physical properties vastly different than gold's, e.g., electric bulbs' filaments are generally made of tungsten.
