Gold is a precious metal. Precious metals' weights are given in TROY ounces and pounds. Other substances' weights are given in AVOIRDUPOIS ounces and pounds. One troy ounce weighs more than one avoirdupois ounce. One troy pound contains TWELVE troy ounces. One avoirdupois pound contains SIXTEEN avoirdupois ounces. Google for how many grains are in each type of ounce and you can compute how many grains are in each type of pound. Thus one avoirdupois pound is heavier than one troy pound. Fortunately, the definition of "grain" is the same for both weight systems.

"1 oz of gold weighs more than 1 oz of water while 1 lb of gold weight lots less than 1 lb of water - the water is 21.53% heavier. " Are you sure we're not confusing "mass" for weight? Is not an ounce and ounce? What was the old question, which is heavier a ton of bricks or a ton of feathers? I'll think on that one durring my extra hour of sleep Sunday...
