Larger pins for the 300B, and such, whether hollow or solid are often 'barrel' plated - where they are tumbled and rotated in the plating solution, like a coffee roaster. So the entire part is plated. Since the amount of gold on each part is so thin, it's cheaper than having machinery/fixtures to just plate one side.
