  LINCOLN CENT AS TIRE TREAD GAUGE
  

  Responding to last week's item on the subject of using a
  Lincoln Cent as a tire tread guage, Dave Lange writes:
  "This practice has been around for many years. Unfortunately,
  the distance between the top of Lincoln's head and the
  edge of the cent has varied considerably since 1909. That
  distance grew progressively smaller between 1909 and 1968,
  as the obverse master hub expanded ever-so-slowly outward
  from its center as the result of compression in the annual
  sinking of a fresh master die. A renewed master hub in
  1969 has been followed by several others since then, this
  operation now being performed each and every year. The
  determination of wear in a tire's tread thus may vary
  greatly, depending on the date of the cent used. Try
  gauging your tire wear with a cent from the 1960s, and
  you may find yourself receiving a panoramic view of the
  surrounding countryside the next time you hit a wet patch."
