AI Appraisal Estimate

This is a large, circular tempered glass serving platter or dinner plate manufactured by Arcoroc in France. The piece is part of the popular 'Vigne' (Grape) collection, characterized by its textured, embossed underside that features a repeating motif of grape clusters alternating with vine leaves around the rim. The center of the plate displays a sunburst or starburst radial pattern consisting of vertical ribs and bead-like accents, surrounded by a circular dotted border. Physically, the glass has a clear to slightly greenish-tinted cast, typical of mid-century mass-produced soda-lime or tempered glass. The edges are slightly scalloped or wavy rather than perfectly smooth, adding to the organic feel of the grape motif. The construction is pressed glass, where the pattern is molded into the base, leaving the top surface smooth for food service. Based on the manufacturer and style, this piece likely dates from the 1970s to the 1990s. The condition appears to be good with no visible chips or cracks, though typical light surface scratches from utensil use may be present upon closer inspection. The Arcoroc brand is noted for its durability and 'France' is often embossed on the bottom to denote origin.

Based on my examination of the Arcoroc France 'Vigne' Grape Pattern plate, I identify this as a genuine piece of vintage pressed tempered glass from the late 20th century. The piece exhibits the characteristic embossed grape cluster and vine leaf motif synonymous with the Vigne line. The clarity and slight greenish tint of the glass are consistent with Arcoroc's proprietary production methods in France during this era. The condition appears 'Excellent-Vintage,' with the scalloped edges showing no significant chipping or 'flea bites' common in glassware of this age. Market-wise, Arcoroc was a high-volume manufacturer; consequently, this pattern is neither rare nor scarce. Comparables found on secondary markets like Etsy and eBay frequently sell in the $12 to $30 range depending on the specific diameter and regional demand. While highly durable due to the tempering process, the value is restricted by the item's mass-produced nature and high survival rate. This valuation assumes the plate is free of deep utensil scarring and clouding (etching) caused by dishwasher chemicals, which can only be definitively confirmed through a 'light-catch' physical inspection. For full authentication, I would need to verify the 'FRANCE' embossing on the base and inspect for microscopic stress fractures. Without a physical tactile inspection, I cannot rule out minor surface abrasions or determine the exact glass density. However, based on the visual evidence, it serves as a functional and aesthetically pleasing example of mid-to-late century French kitchenware.
