AI Appraisal Estimate

This is a vintage Roseville Pottery piece from the Clematis pattern line, which was originally introduced by the Roseville Pottery Company in 1944. The item is a flared, conical-shaped vase or planter featuring a muted green matte glaze base. It is decorated with large, raised-relief Clematis blossoms in shades of dusty pink and pale yellow, accented with long, trailing green leaves and stems. A distinctive characteristic of this line is the textured background, which features subtle concentric swirling lines that resemble tree rings or combed sand. The construction is heavy molded earthenware, typical of mid-century American art pottery. The flared rim flows smoothly into the body, tapering down to a small, circular foot. In terms of condition, there is prominent white mineral buildup and lime scaling visible around the base, likely from use as a functional planter with hard water. While the relief carving remains crisp, there appears to be some localized surface grime and slight crazing inherent to age. Authentication would typically be found on the underside in the form of a raised 'Roseville U.S.A.' mark along with a shape number, likely in the 400 or 600 series range for this specific form factor.

Based on my examination of the provided descriptions and images, I have appraised this Roseville Clematis vase (likely shape 455-6 or similar). The Clematis line, introduced in 1944, represents the transitional late period of Roseville production. The relief molding appears crisp, and the color palette is consistent with the standard 'Forest Green' glaze variant. However, the condition is the primary factor limiting its market value. The prominent white mineral buildup and lime scaling at the base suggest long-term use as a functional planter. Unlike surface grime, these deposits often chemically bond with the matte glaze or hide permanent etching. While the piece appears authentic based on the characteristic textured background and molded handles, I cannot verify the 'Roseville U.S.A.' raised mark or shape number without viewing the base. The market for mid-century Roseville remains stable but highly sensitive to condition. In 'Mint' condition, this shape typically commands $100-$125; however, the present scaling and potential crazing justify a 50-60% reduction. A full authentication would require a tactile inspection to ensure the lime hasn't caused permanent pitting, a check for professional restorations under UV light, and verification of the bottom stamp. For insurance purposes, this item is valued in its current 'as-is' state.
