Also known as
Toon Koster, Antonius Henricus Koster, A.H. Koster
Anthonius Henricus Koster (1913–1989), also catalogued as Toon Koster and Antonius Henricus Koster, was a Dutch painter and draughtsman. The public reference material available here is concise, but its linked authority records connect these names to the same Netherlands-associated artist. Koster is best known for landscape painting, particularly scenes shaped by dramatic skies. Authority-linked work titles also point to wooded terrain and fishermen in a boat, making rural land, water, and changing weather useful visual cues when reviewing attributed works. Collectors may encounter his work under the familiar name Toon Koster, the initials A.H. Koster, or variants of his given name, so signatures and catalogue entries should be checked carefully. No movement or school is assigned here because the collected sources do not substantiate one. Identity, medium, subject, and object-specific evidence therefore provide a sounder basis for research than unsupported stylistic labels.

Common works and media
Available biographical evidence chiefly associates Koster with landscape paintings and dramatic skies. Authority-linked titles also document woodland imagery and fishermen in a boat. Works offered under Toon Koster, A.H. Koster, or a variant spelling of his full name should be matched through signatures, inscriptions, medium, subject, and provenance rather than name similarity alone. The collected sources do not establish a documented print, sculpture, ceramic, or edition practice.
Market and appraisal context
The collected market data is limited and should not be treated as a general price benchmark. Appraisily's data-basis section reports five matched auction records, four with prices, and an observed range of $120 to $200, while another section of the same page reports zero tracked lots. That inconsistency requires caution until the underlying records are reconciled. For an individual work, useful comparisons should match the medium, dimensions, date, landscape subject, condition, signature, and attribution confidence as closely as possible. Provenance, restoration history, exhibition or catalogue references, and the reporting of buyer premiums can also affect how an auction result should be interpreted.

Appraisal caveats
- The collected Appraisily page contains conflicting summaries: one section reports zero tracked lots, while its data-basis section reports five matched records, four with prices.
- The reported auction sample is too small and internally inconsistent to support a general price prediction.
- Private sales, incomplete auction feeds, attribution changes, and differences in reported buyer premiums may not be represented consistently.
- A final appraisal requires object-specific examination of attribution, condition, dimensions, provenance, and comparable works.
