Off Metal Wrong Planchet Transitional Error Lookup
Bounded offline reference: Wrong-planchet/off-metal errors require independently verified issue, weight, dimensions and composition with alternative causes excluded. Source: Mint-error catalogue and grading guidance. Appearance alone does not distinguish a genuine mint error from plating, damage or counterfeit. Supported topic keys: summary, reference, limitations. No complete external corpus or live policy implied.
Description
A wrong-planchet attribution needs issue-specific evidence of dimensions, mass and composition.
A wrong-planchet attribution needs issue-specific evidence of dimensions, mass and composition.1
This lookup explains the chosen topic using a bounded stored reference.
When to use Off Metal Wrong Planchet Transitional Error Lookup
Use this tool to read a bounded explanation for an exact reference topic. Establish the coin issue, source edition, measurement basis and reference date where applicable.
How to use Off Metal Wrong Planchet Transitional Error Lookup and understand its results
- Establish the coin issue, source edition, measurement basis and reference date where applicable.
- Enter topic, using the field meanings and rules below, then run the tool.
- Read result. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| topic | Topic | string | Required |
Choose one exact topic token from the table. The implementation looks up the stored value and returns it in the documented output field. Matching is case-sensitive; unrecognized tokens fail. This is an offline bounded reference, not a live catalogue or independent attribution.
| Topic token | Stored value |
|---|---|
| summary | Wrong-planchet/off-metal errors require independently verified issue, weight, dimensions and composition with alternative causes excluded. |
| reference | Mint-error catalogue and grading guidance. |
| limitations | Appearance alone does not distinguish a genuine mint error from plating, damage or counterfeit. |
value=referenceTable[exactToken] Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |

}Limitations and assumptions
Coin identification, reference applicability and measurement uncertainty require separate evidence. A returned explanation or arithmetic agreement does not establish authenticity, a certified grade or a current market value. Appearance alone does not distinguish a genuine mint error from plating, damage or counterfeit.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
