Gum Condition Descriptor Selector (MNH/MH/MLH/Used)
Select a descriptive caller-observed use/gum/hinge label; original gum cannot be established from these flags. Caller independently verifies observations, reference edition, units and applicability; not a grading-service certificate, authentication, conservation treatment, actual market price or legal/insurance entitlement.
Description
Gum-condition abbreviations describe observations of use, gum presence, and hinge trace.
Gum-condition abbreviations describe observations of use, gum presence, and hinge trace.1
This selector applies an explicit precedence rule to supplied booleans rather than authenticating the gum or grading a specimen.
When to use Gum Condition Descriptor Selector (MNH/MH/MLH/Used)
Use this tool when you need to summarize the supplied collecting records or matched observations. Prepare independently verified observations, reference edition/context, and matching units or currency basis.
How to use Gum Condition Descriptor Selector (MNH/MH/MLH/Used) and understand its results
- Prepare independently verified observations, reference edition/context, and matching units or currency basis.
- Enter postallyUsed, gumPresent, hingeTrace, lightHingeTrace, following the field table and calculation rules below, then run the tool.
- Read descriptor. For result objects, inspect the nested output fields below, including any missing evidence or selected indices.
- Correct any input issues and run again. Before using a successful result, review its units, signs, evidence coverage, and stated model or reference assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| postallyUsed | Postally used | boolean | Required |
| gumPresent | Gum present | boolean | Required |
| hingeTrace | Hinge trace | boolean | Required |
| lightHingeTrace | Light hinge trace | boolean | Required |
Require boolean postallyUsed, gumPresent, hingeTrace, and lightHingeTrace; a light trace requires hingeTrace even if another branch would win. Choose Used first, then Unused-no-gum when gum is absent, then MNH without trace, MLH for a light trace, and MH otherwise.
descriptor=used?Used:!gum?Unused-no-gum:!hinge?MNH:light?MLH:MH Read these symbols with the field meanings and branch or reference rules above.
| Output field | Meaning | Value type |

}Limitations and assumptions
Observations, reference edition, and applicability are independently supplied. Arithmetic and reference summaries do not provide authentication, a certified grade, or an actual market price.
Missing required fields, unknown fields, wrong types, and violated calculation rules return input issues.
Alternative or Complementary methods
For a related task, use Hinge Remover Trace Penalty Rater: A hinge trace may affect a condition reference or valuation, depending on the stamp and grading convention. This rater interpolates a supplied hinge-trace penalty curve rather than imposing a universal deduction. For a complementary step, use Regummed Detection Gloss Test Flag Checker: Gum gloss observations can be one part of reviewing whether gum condition merits further attention. This checker compares supplied measurements with caller bands and retains unknown assessments without authenticating original gum.
