The gold pan with areas of differing surface textures includes a disc-shaped, planar bottom panel, and an upwardly and outwardly extending frustoconical sidewall attached to the circular perimeter of the bottom panel. The circular top of the frustoconical sidewall includes a rounded upper rim. The rounded upper rim includes reinforcement ribs, and a hole defined therethrough for hanging the gold pan on a hook or other structure. A downwardly extending flange is attached to the circular perimeter of the bottom panel, for stabilizing the pan on a support surface. The frustoconical sidewall includes a set of circumferentially extending tapering riffles. In addition, the frustoconical sidewall may include a smooth area as well as a second set of circumferentially extending riffles. The second set of riffles can have a constant width and height.
