This is a large, oval-shaped serving platter crafted from hand-polished cast aluminum, a signature material of the Arthur Court brand. The centerpiece of the tray features a highly detailed, relief-modeled longhorn steer head, with the long, curved horns extending across the width of the basin to create a functional partition within the dish. The rim of the platter exhibits a decorative scalloped or 'pie crust' edge. Physically, the platter displays a bright, silvery luster characteristic of sand-cast aluminum. The craftsmanship is evident in the intricate textures of the steer's hair and the segmented detail on the horns. In terms of condition, the piece shows moderate surface wear consistent with previous use and age, including fine scratches, some pitting in the metal, and minor oxidation spots particularly visible along the right edge. There are also adhesive remnants from a pricing label on the interior surface. This style of western-themed serveware gained significant popularity in the late 20th century, likely dating from the 1980s or 1990s. The heavy-weight construction and detailed casting suggest higher-end decorative quality commonly associated with the Arthur Court aluminum line.

I have examined the images of this Arthur Court Designs Longhorn Steer Steak Platter. Based on the casting quality and the specific relief work of the longhorn steer—a staple of the brand's Western collection—the piece appears to be an authentic example of Arthur Court sand-cast aluminum, likely manufactured between the late 1980s and mid-1990s. The luster is consistent with the hand-polished finishes typical of this era. Regarding condition, I observed surface scratches, pitting, and oxidation spots on the rim, which are common for used aluminum serveware but do negatively impact the value compared to mint-condition pieces. The adhesive residue is a minor cosmetic issue that can likely be remedied without damaging the metal. Market demand for Arthur Court remains stable, particularly for Western-themed motifs which have a dedicated collector base; however, supply for this specific platter is moderate. Comparable sales for similar vintage Arthur Court platters in this condition typically fall within the $60 to $100 range. A major limitation of this appraisal is the inability to verify the maker's mark (usually found on the underside) or to tactilely assess the weight and density to rule out contemporary reproductions. For a definitive authentication, I would need to inspect the 'Arthur Court' copyright stamp, verify the absence of structural cracks under magnification, and confirm the item's provenance. No scientific testing is required, as the identity of the alloy is characteristic of the brand's production.
