      Lindy asks a legitimate question about how it's possible to have a
      fake brockage on a coin that's close to normal weight. Here are some
      possibilities:

      1. Use a genuine in-collar uniface strike and impress a brockage into
      the blank face. We've already come across one of those on ECIE.

      2. Use a genuine off-center uniface strike and impress a brockage
      into the blank surface. All off-center coins with unexpanded
      brockages should be checked carefully for this alteration.

      3. Take a coin (normal or error) and tap down the design with a small
      peening device (hand-held or electrical) so it is very flat. Then
      polish the metal away. I once saw an alleged uniface state quarter
      in which the entire obverse design had been obliterated by delicate
      peening of the surface. All you could see was a field filled with
      shallow pockmarks. Not much metal would be removed by polishing if
      you first reworked the surface in this manner.

      4. Find a coin (normal or error) that's at the high end of the normal
      range of variation and grind off one face. The altered coin may
      still hover at the low end of normal variation since you're starting
      with an unusually heavy coin.

      It's a scary world out there, folks. Never underestimate the
      ingenuity of the criminal mind.
