Type One Type Two Standing Liberty 1917 Change Lookup
Bounded offline reference: Standing Liberty quarters changed in 1917 from Type Ito Type II, including the covered/chained-mail torso and reverse changes. Source: US Mint/Standing Liberty quarter catalogues. Date alone does not identify type; later date-recessing changes are separate. Supported topic keys: summary, reference, limitations. No complete external corpus or live policy implied.
Description
Standing Liberty quarter types distinguish design changes within a dated coin series.

This lookup explains the chosen topic using a bounded stored reference.
When to use Type One Type Two Standing Liberty 1917 Change 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 Type One Type Two Standing Liberty 1917 Change 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.

}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. Date alone does not identify type; later date-recessing changes are separate.
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.
Alternative or Complementary methods
For a related step, use Seated Liberty Arrows At Date Weight Change Marker: Arrows at the date can serve as a design marker associated with an issue-specific weight change. For a complementary comparison, use Off Metal Wrong Planchet Transitional Error Lookup: A wrong-planchet attribution needs issue-specific evidence of dimensions, mass and composition.
