AI Appraisal Estimate

This is a fine porcelain vase produced by the renowned manufacturer Royal Copenhagen in Denmark. The item features a smooth, glazed white porcelain base with a distinctive light blue or lilac matte/bisque-style exterior finish typical of certain mid-20th-century Scandinavian design aesthetics. The underside displays the company's iconic backstamp: a green crown logo surrounded by 'ROYAL COPENHAGEN DENMARK', three blue hand-painted waves representing Denmark's three straits (the Oresund, the Great Belt, and the Little Belt), and a painter's signature in blue script. Additionally, numeric markings '288' and '121' are hand-written in green, likely signifying the shape and pattern/decor numbers respectively. A small green dot or line under the letter 'G' in 'Copenhagen' suggests a production period between 1969 and 1974. The vase shows minor shelf wear on the unglazed foot rim and remains in excellent vintage condition with no visible chips, cracks, or repairs. The craftsmanship reflects the high quality associated with Danish porcelain, characterized by clean lines and an elegant, minimalist form. The presence of a contemporary 'Goodwill' thrift store sticker indicates its recent secondary market history.

Based on my visual examination of the provided descriptions and photographic evidence, I have assessed this Royal Copenhagen porcelain vase, shape 288, decor 121. The green backstamp with a bar under the 'G' in COPENHAGEN definitively dates this piece to the 1969-1974 production period. The three blue waves are sharp and well-executed, consistent with authentic factory markings. The condition appears to be 'Excellent' with no evidence of crazing, chips, or professional restoration. The matte lilac/blue finish is a characteristic Mid-Century Modern aesthetic that remains popular among Scandinavian design enthusiasts. However, this specific shape and monochrome palette are relatively common compared to the hand-painted 'Flora Danica' or complex crystalline glaze series. Market demand for small Royal Copenhagen giftware is steady but high-volume, with many similar examples appearing on the secondary market via online auctions and estate sales. The presence of a thrift store sticker suggests a lack of documented provenance, which is common for such items. My valuation is based on recent realized prices for late 20th-century Danish porcelain of similar size and complexity. Limitations: This appraisal is based strictly on digital images. A physical inspection is necessary to check for 'seconds' markings (scratches through the blue waves), internal hairline cracks not visible to the eye, or tactile inconsistencies in the glaze. To fully certify authenticity and value, I would require a high-resolution microscopic view of the backstamp to ensure it is not a later overglaze forgery and a blacklight test to rule out modern resin repairs.
