Die Axis Clock Position Lookup
Convert exact integer die-axis clock notation1–12to clockwise angle from12oclock, viewer convention. Not observed rotation deviation or a grade/authenticity determination.
Description
A clock-position die axis describes the reverse’s rotation relative to an established obverse orientation.
A clock-position die axis describes the reverse’s rotation relative to an established obverse orientation.1
This tool calculates the stated record summary using your supplied observations.
When to use Die Axis Clock Position Lookup
Use this tool to calculate or review the supplied observations under the stated rules. Establish the coin issue, source edition, measurement basis and reference date where applicable.
How to use Die Axis Clock Position Lookup and understand its results
- Establish the coin issue, source edition, measurement basis and reference date where applicable.
- Enter clockPosition, 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 |
|---|---|---|---|
| clockPosition | Clock position | number | Required |
Use a safe-integer clock position 1..12 after independently establishing obverse orientation. Return (position modulo 12)×30 clockwise degrees; twelve maps to zero.
degreesClockwise=(clockPosition%12)×30 Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or qualified reference | object |
| result.axisDegreesClockwise | axis Degrees Clockwise | number |

}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.
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.
