Things to keep in mind when looking at the above results (unsolds are not included):

  1. It is important to look at the individual data points listed above. Price swings up may be due to varieties such as broken hat or other positives such as cancels. Price swings down may be due to factors such as faults on items that would have graded higher if they were sound, and may not be considered as desirable as a sound copy in this grade.
  2. At the time of an auction, the SMQ value has already been published and is available to bidders. Increases or decreases in SMQ value prior to the auction may affect the price realized.
