Centering is only one part of condition; faults, gum, cancellation, color, and alterations matter.

Identification rule: record what is visible before assigning a catalog number or value.

What to record

What commonly causes mistakes

A practical research sequence

  1. Identify the exact stamp first.
  2. Inspect front and back under magnification.
  3. Record every fault separately.
  4. Use expertization for consequential decisions.

Condition and value

Value depends on exact identity, condition, centering, gum or cancellation, faults, certification, demand, and a defensible comparison set. A famous design does not automatically make an individual example rare.
