Polishing a Coin with Progressively Higher (Finer) Levels of Grit
In this intriguing demonstration, we see a 10 yen coin polished with progressively higher (finer) levels of grit (that’s the number shown below each stage of polish).
It’s pretty remarkable how shiny and reflective it gets by the end! Oh and look out for Woody? lol
