Selected title: Whizzing
Explanation: The alteration of a coin's appearance by use of a rotating bristled (wire or other material) brush to move or remove metal from the surface. This process generally gives a coin the artificial appearance of being in a higher grade than it actually is. Areas of a whizzed coin usually show a series of minute scratches or surface disruptions simulating artificial luster, and the buildup of metal ridges on raised letters or other design features
