Gold filled could sometimes be understood the same as Gold plated. This is a common mistake in the antique jewelry industry.
Gold-filled jewelry composed of a solid layer of gold (typically constituting at least 5% of the items total weight) mechanically bonded to a base of either sterling silver or some base metal. Actually, it is more valuable than the Gold plated jewelry. It is 5 to 10 times thicker than that of a regular gold plating and 15 to 25 times thicker than that of gold electroplate.

Electroplated Gold: A thin layer of solid gold added to a base metal through the use of electricity, slightly thicker than gold plate.
Gold Plated: A thin layer of solid gold added to jewelry - can be rubbed off easily.
