Die Polish vs. Flow Lines
Classify caller-observed indicators for die polish vs. flow lines while preserving mixed and insufficient evidence.
Description
Die-polish and metal-flow-line review compares declared repeatability and line orientation.
Die-polish and metal-flow-line review compares declared repeatability and line orientation. This classifier summarizes observations without inspecting their relief or location.1
Classify caller-observed indicators for die polish vs. flow lines while preserving mixed and insufficient evidence.
When to use Die Polish vs. Flow Lines
Use this tool to classify caller-observed indicators for die polish vs. flow lines 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 Die Polish vs. Flow Lines 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 repeatOnDiePair, stopsAtDevices, radialFromCenter, formsLusterCartwheel 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 |
|---|---|---|---|
| repeatOnDiePair | Repeats on a die pair | boolean | Required |
| stopsAtDevices | Stops at devices | boolean | Required |
| radialFromCenter | Radial from strike center | boolean | Required |
| formsLusterCartwheel | Forms cartwheel luster | boolean | Required |
Set the four flags. Count repeatOnDiePair, stopsAtDevices for die-polish-lines and radialFromCenter, formsLusterCartwheel for metal-flow-lines. 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 "die-polish-lines", "metal-flow-lines", "mixed-evidence", "insufficient-evidence" |
| firstScore | Die-polish indicators | integer; minimum: 0 |
| secondScore | Flow-line indicators | integer; minimum: 0 |
{
"input": {
"repeatOnDiePair": true,
"stopsAtDevices": true,
"radialFromCenter": false,
"formsLusterCartwheel": false
},
"output": {
"classification": "die-polish-lines",
"firstScore": 2,
"secondScore": 0
}
}Limitations and assumptions
The evidence is equally weighted and no surface image or die pair is verified. Other scratch and alteration explanations are not modeled.
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.
