  TAPERED COLLAR THEORY: WHY SAYS CENT'S HEADS SIDE IS SMALLER THAN TAILS
  

  John Dannreuther writes: "Kudos to David Lange on the tapered
  collar theory. I thought of it, and had dismissed it, but
  his logic seems right with the horizontal press. I wonder
  if the ejection lines on the "tapered" cents are different
  than those of the previous collars? They should be less
  intense as the collar widens."
