It is important to look at the individual data points listed below. 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.
When looking at multiple grades on the graph, grades with the same population numbers may show overlapping.
