Proof vs. Business Strike
Classify caller-observed indicators for proof vs. business strike while preserving mixed and insufficient evidence.
Description
Strike classification distinguishes production categories from surface appearance alone.
Strike classification distinguishes production categories from surface appearance alone. This tool compares declared proof and business-strike indicators without requiring complete evidence.1
Classify caller-observed indicators for proof vs. business strike while preserving mixed and insufficient evidence.
When to use Proof vs. Business Strike
Use this tool to classify caller-observed indicators for proof vs. business strike 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 Proof vs. Business Strike 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 documentedProofIssue, squaredRims, ordinaryProductionIssue, singleStrikeTexture 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 |
|---|---|---|---|
| documentedProofIssue | Documented proof issue | boolean | Required |
| squaredRims | Squared rims | boolean | Required |
| ordinaryProductionIssue | Ordinary production issue | boolean | Required |
| singleStrikeTexture | Ordinary strike texture | boolean | Required |
Set the four flags. Count documentedProofIssue, squaredRims for proof-strike and ordinaryProductionIssue, singleStrikeTexture for business-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 "proof-strike", "business-strike", "mixed-evidence", "insufficient-evidence" |
| firstScore | Proof indicators | integer; minimum: 0 |
| secondScore | Business-strike indicators | integer; minimum: 0 |
{
"input": {
"documentedProofIssue": true,
"squaredRims": true,
"ordinaryProductionIssue": false,
"singleStrikeTexture": false
},
"output": {
"classification": "proof-strike",
"firstScore": 2,
"secondScore": 0
}
}Limitations and assumptions
Issue documentation and coin surfaces are not inspected. One flag can win even while contrary evidence remains present.
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.
