Gianni Motta Persolan Pista 1979

Each and every aluminium component was polished by hand using only the sand water papers (120, 220, 400,600, 800, 1000, 1200, 1500, 2000, 2500) and finished mechanically on a lathe with the aid of the felt and the polishing paste. When riding, one can spot the sky depicted on the stem and a clear rolling/flashing light reflex of the chainring on concrete. I spent no fewer than 9 hours polishing the stem alone.

That's got to be worth a grand alone.
