Message:: [QUOTE="Insider, post: 2436304, member: 24314"]What you say is true.  I happen to know the actual "story" from the horse's mouth so to speak. You can look it up. Prior to 1972, the ANA used the word "cleaning" in their written definition of "Whizzing."  The original authenticators at ANACS while it was in DC were well acquainted with whizzed coins as this was one of the most prevalent surface alterations at that time.  They noticed that every coin that was altered by the TRUE WIZZING METHOD displayed a buildup of a thin strip of metal along the edge of the relief details.  That's what separated "whizzing" from ALL OTHER FORMS of mechanical cleaning.  From that time on, WHIZZING HAD ONE FIRM, UNIVERSAL DEFINITION as taught by the ANA. If there was no buildup , it was not whizzed.  Anyone ignorant of this fact is free to call a buffed up coin whizzed but they would be incorrect.  Furthermore, in the 1980's a newer form of whizzing appeared.  It was called "micro-whizzing" and first appeared on Indian cents and early Lincolns.  Authenticators at INSAB (the original horse's mouth mentioned above) could tell the surface was altered but needed a stereo microscope to see the ridge.  Many of these coins were slabbed as original by PCGS and NGC until they finally caught on much later.[/QUOTE]
