Polished cast-aluminum style decorative charger with swirl motif

This item is a circular decorative charger or serving plate featuring a wide rim embellished with a recurring relief-molded spiral or snail-shell motif. The material appears consistent with sand-cast polished aluminum, a common choice for artisanal serveware due to its luster and weight. The surface displays a reflective, silvery sheen with visible circular brushing marks and micro-scratches consistent with use and age. There are no maker's marks or signatures visible on the face of the item in the provided image. The owner has attributed this piece to Mariposa from 1992, which is stylistically consistent with the brand's 'Brilliance' or 'Spiral' collections; however, this claim remains unverified without a physical inspection of any underside hallmarks. The craftsmanship shows a hand-finished quality with slight irregularities in the spiral patterns, suggesting a cast production method rather than stamped industrial manufacturing. Some surface dulling or oxidation is visible in the recessed areas of the swirls, which is common for aluminum alloy pieces over time.

Based on the provided image, I have examined this sand-cast aluminum decorative charger. The item features a spiral motif consistent with the aesthetic of high-end giftware from the late 20th century. Per user submission, the piece is attributed to Mariposa, circa 1992. Based on what I can see, the luster and hand-finished irregularities are characteristic of the 'Brilliance' or 'Spiral' collections attributed to that maker, though I cannot verify this identity without a physical inspection of the underside for hallmarks or signatures. My estimate assumes the attribution provided is correct. Sand-cast aluminum pieces attributed to recognized artisanal brands typically maintain a stable secondary market value between $45 and $75, depending on the diameter and specific pattern rarity. However, I can't verify the material composition or age from a photo alone; surface micro-scratches and oxidation suggest use, which is common. If this item were determined to be an unbranded 'in the style of' piece or a generic mass-produced reproduction, the value would likely decrease to a range of $15–$25. Market demand for such serveware remains steady for collectors of mid-to-late 20th-century table settings, though it is not presently a high-growth category. To confirm the identity and potentially reach the higher end of the estimate, an in-person examination by an expert to locate known maker marks and a review of any original provenance or purchase documentation would be required. The current valuation is a working hypothesis based on the assumption that the owner's attribution is accurate.
