Catalogued entries include documented types and sourced examples of individual museum objects. A research scope is an issuer, series or denomination group awaiting further transcription. Museum examples may need additional research before their wider type can be identified. Image presence does not by itself establish reuse rights or make an entry complete.
Confidence measures the documented evidence for attribution. It is not a grade, valuation or guarantee of authenticity.
Each scope is a bounded claim that can be audited — not a claim about the world's collectibles as a whole.
