About Grant Speed

Born

1930

Died

2011

Nationality

American

Grant Speed (1930–2011) was an American sculptor associated in public authority records with Western art. Wikidata and VIAF identify him specifically as an American Western sculptor, while VIAF, IdRef, and linked library identifiers establish a consistent identity across international authority systems. Collectors are therefore most likely to encounter his name in connection with sculpture representing the people, animals, and broader visual culture of the American West, although the collected sources do not document a detailed subject catalogue or individual series. Appraisily's matched auction data also places works under sculpture and mixed media, but its category coverage is described as broad or sparse. The available source pack securely supports Speed's life years, nationality, occupation, and Western context; it does not establish exact birth and death dates, specific materials, training, institutional affiliations, or a complete exhibition history. Those details should be checked against documentary records when identifying or appraising an individual work.

SculptureAmerican West

Common works and media

Sculpture is the securely documented work type for Grant Speed, whose authority records describe him as a Western sculptor. Appraisily's matched auction page also includes sculpture and mixed media among its category labels. The collected sources do not reliably establish particular metals, casting methods, edition sizes, named series, or recurring individual subjects, so those characteristics should be verified from the object, inscriptions, foundry or edition marks, provenance, and supporting documentation rather than inferred from the artist's name alone.

Market and appraisal context

Grant Speed's auction results should be compared with genuinely similar works rather than read as a single price benchmark. Relevant distinctions include medium, dimensions, date, subject, condition, restoration, signature or inscriptions, edition information, attribution confidence, provenance, exhibition history, and catalogue references. Recent public sales can provide useful comparisons when the objects share these characteristics. Appraisily's market index contains matched records for the artist, but its displayed categories are broad and the public record may omit private transactions or incomplete auction feeds. Reporting conventions can also differ over whether totals include buyer's premiums or other fees. A final appraisal should therefore combine record matching with inspection, condition analysis, authorship evidence, and carefully selected comparable sales.

Appraisal caveats

  • The collected market page says its category concentration is broad or sparse, so category labels should not be treated as a definitive catalogue of Grant Speed's output. Source: https://appraisily.com/artist/grant-speed/
  • Public auction records are appraisal starting points rather than final valuations; private sales, incomplete feeds, reporting differences, and later attribution changes may not be represented. Source: https://appraisily.com/artist/grant-speed/
  • Authentication, attribution, and condition can materially affect value relative to apparently similar public auction records. Source: https://appraisily.com/artist/grant-speed/
