Value & Age

Estimated Market ValueNot an official valuation

Approximately $8–$20 per board foot for ordinary figured walnut; exceptional slabs may cost considerably more.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Cannot be determined reliably from a photograph; the surface appears used or oxidized but not necessarily antique.

Common Uses

Furniture, cabinetry, veneer, gunstocks, turned objects, carving, architectural millwork, and decorative slabs.

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachian regions.

Workability

Generally machines and sands well, though irregular grain can tear out; glues, screws, and finishes reliably.

Finish Recommendations

Apply a sanding sealer followed by oil, shellac, lacquer, or polyurethane; wipe-on oil enhances the figure. Sand evenly to avoid blotchy sheen.

Notable Features

Distinctive dark color, attractive flowing figure, moderate density, and good dimensional stability.
