Colonial Strike Classifier

Classify caller-observed indicators for colonial strike classifier while preserving mixed and insufficient evidence.

Description

Colonial strike review compares declared planchet and device characteristics.

Colonial strike review compares declared planchet and device characteristics. Broad production labels require corroboration beyond a feature count.^[1]

Classify caller-observed indicators for colonial strike classifier while preserving mixed and insufficient evidence.

When to use Colonial Strike Classifier

Use this tool to classify caller-observed indicators for colonial strike classifier while preserving mixed and insufficient evidence.

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 Colonial Strike 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 irregularPlanchet, offCenterDevices, regularRoundPlanchet, machineEdgeDevice using the field table and calculation rules, then run the tool.
Read classification, firstScore, secondScore. 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
irregularPlanchet	Irregular planchet	boolean	Required
offCenterDevices	Off-center devices	boolean	Required
regularRoundPlanchet	Regular round planchet	boolean	Required
machineEdgeDevice	Machine-applied edge device	boolean	Required

Set the four flags. Count irregularPlanchet, offCenterDevices for hammered-cob and regularRoundPlanchet, machineEdgeDevice for milled-strike. Both zero yields insufficient-evidence; equal positive scores yield mixed-evidence. Otherwise return the higher-score label with both counts.

firstScore=selected first-side flags; secondScore=selected second-side flags; classification follows their comparison

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

Output field	Meaning	Value type
classification	Classification	string; one of "hammered-cob", "milled-strike", "mixed-evidence", "insufficient-evidence"
firstScore	Hammered-cob indicators	integer; minimum: 0
secondScore	Milled-strike indicators	integer; minimum: 0

  "input": {
    "irregularPlanchet": true,
    "offCenterDevices": true,

Limitations and assumptions

The tool does not identify a ruler, mint, date or denomination. Shape and placement can have multiple causes and are supplied observations.

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.

Alternative or Complementary methods

Use Cob Assayer Record Match: Compare caller-supplied expected and observed records for cob assayer record match. For a complementary task, use Ptolemaic Bronze Record Lookup: Retrieve a caller-supplied Ptolemaic bronze denomination record by identifier while preserving its weight standard and catalogue reference.
