Silver faces, copper crowns, I travel the world without leaving town. I read dates, mint-marks, tiny crests, I judge old kings by how metal rests. History clinks in my careful hand, Empires fit in a small round span. I chase rare years that others miss what am I, in love with this?

You think of me as grey and dull, but I can be surprisingly colourful. Often nocturnal, drawn to flame, who am I, this butterfly's cousin with the short name?

I share my name with something in your blood, yet I’m also stacked in a gym and swung on a field. I smooth out wrinkles without fingers, but I can’t move at all without someone guiding me. I live on the periodic table, but I’m just as at home in a closet before work. What am I?

What is small, often sweet, and helps websites remember you?

Visitor from afar, not bound by earthly chains, often seen under silver lights, a mystery in cosmic tales.
