Below is an explanation of the stamp, coin, and banknote catalog numbers used by this Website. For stamps, Scott numbers are preferred when available, otherwise Michel numbers are used. If neither are availalbe, then other catalog numbers may be used. If no known catalog numbers are available, items may be noted as either "Unknown" or "Unlisted", depending on whether a catalog number may eventually be assigned or will likely never be assigned.
