HOWARD GIBBS MEXICAN SUD NUMBERING SYSTEM

  Bob Dunfield  writes: "Sincere thanks to all who helped in
  trying to solve the Gibbs SUD numbering system.
  Unfortunately, the system of identifying varieties of the
  Mexican SUD coins, 1/2 Real - 8 Reales, 1811 -1814, was
  likely part of his personal notes on these issues.  It still seems
  strange, though, that Schulman would have published Gibbs'
  numbers if collectors could not reference them, or understand
  them!

  In the process of identifying numismatists that have used
  numbering systems for identifying these coins, I have found
  several others, but no single publication by any of them that
  identifies the coins, and matches numbers with plated coins.
  Superior's Munoz sale, # 4, June 7, 1982, presented many
  SUD and other War for Independence coins, and most of
  them listed "Vogt numbers" and "Elizondo numbers." Also,
  in the 'Julius Guttag Collection of Latin American Coins',
  Arranged by Edgar H. Adams, 1929, and Quarterman
  Publications, 1974, has many SUD pieces, all identified by
  "numbered dies." Groups of 8 Real SUDs are plated, with
  the words underneath..."Seventh Die, Eighth Die, etc..!  For
  coins without pictures, they are listed simply by lot number,
  date, value, and the "Die Number."

  It would seem important that at one time, these coins were
  identified, described, and plated in a reference book, such
  that collectors would be familiar with Guttag's lot number
  2978, an eight real SUD described simply as "Eighteenth
  Die"!  If such a reference book exists, I would gladly
  purchase it for a reasonable sum!   If there is anything
  separately published by any of these noted numismatists,
  it would be a magnificent find for me!

  Once again, my sincere thanks to all who helped!   I think,
  however, that we have uncovered more questions to be
  answered in the process.  This is good news, though,
  because with so many different numbering and die numbering
  systems out there, the chance of finding a complete one is
  much greater!"
