Checks that apply to any U.S. definitive
- Measure the perforations with a gauge; the same design often exists in two or three gauges, and that is usually what separates the common one from the scarce one.
- Sheet, coil or booklet: coils have two straight edges on opposite sides; booklet panes have one or two straight edges from the pane edge.
- Tagging: hold it under a longwave UV lamp; tagged and untagged printings of the same design are listed separately.
- Condition (centering, gum, cancel) is a separate question from identification.
How to photograph it for identification
Lay the stamp flat on a dark background in daylight, fill the frame, and keep the phone parallel so the perforations are not distorted. Photograph the back too if there is a watermark or gum question. The app reads the design and denomination; the perforation and tagging checks above settle which listing it is.
