The scales on the dragon's chest were dense and interlocking, and because Smaug buried himself in the Golden Silver Sea to sleep, many gold coins were lodged in the gaps.
Later, they got even more messed up, sticking together with the liquid gold.
Although Smaug spun rapidly in the sky, shedding the layer of brilliant liquid gold before it cooled and solidified,
a body as large as 140 meters long couldn't be completely cleaned.
