AI Appraisal Estimate

A pair of contemporary style double old fashioned glasses, likely designed by Vicke Lindstrand for Kosta Boda as part of the Pippi collection. These glasses are characterized by their clear, heavy crystal construction and a cylindrical silhouette that slightly tapers toward the base. Each glass features a thick 'sham' or weighted base, which is distinctively adorned with a single, large controlled air bubble (or 'teardrop') suspended within the solid glass. The rim is fire-polished and thin, indicating high-quality craftsmanship. The glasses appear to be in excellent used condition with no visible chips, cracks, or clouding from hard water deposits; however, minor surface scratches on the underside of the base are typical for this age. This minimalist Scandinavian design originated in the mid-20th century but became a staple of modern barware. The lack of visible etching suggests these may be newer production pieces or the marks have worn off through cleaning. The optical clarity of the glass remains high, reflecting a premium lead or lead-free crystal composition.

Based on my visual examination of this pair of Kosta Boda 'Pippi' double old fashioned glasses, I have assessed them as high-quality examples of Vicke Lindstrand’s mid-century modern design. The heavy sham and characteristic 'teardrop' air bubble are signs of authentic Kosta Boda production. The glasses exhibit excellent optical clarity and fire-polished rims, suggesting they have been well-maintained. The minor base wear mentioned is consistent with age and supports a vintage attribution rather than a contemporary imitation. The current secondary market for Scandinavian barware remains stable, with Pippi remains a sought-after pattern for collectors of minimalist glass. Similar pairs typically sell between $30 and $45 per stem on platforms like 1stDibs or specialized glass auctions. The lack of a visible etched signature slightly limits the premium, though many Kosta pieces originally bore only paper labels. Limitations: From a digital image, I cannot verify the exact lead content or weight, which distinguishes genuine Kosta crystal from lower-quality glass copies. A physical inspection would be required to check for micro-chips along the rim and to verify the 'ring' or resonance of the crystal. Complete authentication would also benefit from original packaging or an acid-etched mark on the base, which sometimes requires specific lighting to reveal.
