When to use Provincial Coin Authority Classifier

Use this tool to classify supplied authority and legend evidence as Roman provincial imperial, civic autonomous, or insufficient; the result is not an attribution.

Prepare documented records or observations for the specific coin or issue context. Enter the required labels, reference table or evidence flags and retain the supporting catalog and examination notes for interpretation.

How to use Provincial Coin Authority Classifier and understand its results

Prepare documented records or observations for the specific coin or issue context. Enter the required labels, reference table or evidence flags and retain the supporting catalog and examination notes for interpretation.
Enter civicEthnicLegend, imperialPortraitOrName, namedRomanAuthority, struckUnderRomanRule using the field table and calculation rules, then run the tool.
Read classification. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
civicEthnicLegend	Civic ethnic legend observed	boolean	Required
imperialPortraitOrName	Imperial portrait or name observed	boolean	Required
namedRomanAuthority	Named Roman authority observed	boolean	Required
struckUnderRomanRule	Evidence supports Roman-period issue	boolean	Required

Set four flags. Return insufficient-evidence unless struckUnderRomanRule is true. Then imperialPortraitOrName or namedRomanAuthority takes precedence over civicEthnicLegend; civic alone yields civic-autonomous.

outside declared Roman rule→insufficient; otherwise imperial/name evidence→imperial; otherwise civic legend→civic-autonomous

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
classification	Authority classification	string; one of "roman-provincial-imperial", "civic-autonomous", "insufficient-evidence"

{
  "input": {
    "civicEthnicLegend": true,
    "imperialPortraitOrName": true,

    "struckUnderRomanRule": true
  },
  "output": {

Limitations and assumptions

The tool does not determine chronology, read portraits/legends or make a catalog attribution. Civic and imperial evidence is resolved by branch priority, not reported as mixed.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
