Site Overview

  • Re-entries and Retouches are considered to be Constant Plate Varieties (CPVs), so we do not need to ask "Is It Constant?". These CPVs are not a part of this effort.

  • Guide dots and Guidelines, similarly, are constant and will not be included.

  • Dots which appear in areas where guide dots are not normally found will be included.

  • Lines which are not clearly guide lines are included.

  • Many of the stamps shown are not likely to be determined to be constant.

  • The darker stamp shades - green especially - may look black in the site images. Users trying to match stamps from their collections should not find this problematic.
