A golden treasure that never stays; The coin whose face gives wealth to all. Strands, nuggets, and dust of gold are all bought with its shining grace... And all are more precious than any gleaming metal. What am I?

Why this works

This riddle cleverly describes the sun through various metaphors related to wealth and value. The "golden treasure that never stays" refers to the sun's light and warmth, which are abundant yet ephemeral, as they change with time and weather. The "coin whose face gives wealth to all" suggests that sunlight is essential for life, much like how currency provides wealth; thus, it enriches nature and humanity. Lastly, "strands, nuggets, and dust of gold" symbolize the various forms of life and resources that depend on sunlight—plants, which create food and oxygen, are indeed more precious than any metallic treasure.
