Mid-century modern style cast metal oversized jacks

This pair of decorative objects appears to be mid-century modern style oversized game jacks. Each item is constructed from what appears to be cast metal, possibly iron or bronze, showing a heavy, textured finish. They feature a central junction with six radiating arms: two arms taper to points, while the other four terminate in rounded spheres. The surfaces exhibit an uneven, aged patina with a mix of dark metallic or blackened areas and burnished brass-colored highlights, particularly on the spherical ends. The construction suggests a casting process, as evidenced by small surface pits and irregularities. No visible maker's marks or signatures are apparent in the image, making this attribution based solely on stylistic features consistent with Brutalist or mid-20th-century decorative motifs. The condition shows visible wear and surface oxidation consistent with age and handling. A handwritten note partially visible in the lower left says 'Jacks,' which mirrors the visual form. Their large scale suggests they are intended for use as bookends, paperweights, or tabletop sculptures rather than play pieces.

Based on my examination of the image provided, these objects appear to be a pair of oversized decorative jacks in the Mid-century Modern or Brutalist style. The value range of $150–$350 is based on the hypothesis that these are vintage mid-20th-century cast metal pieces. Based on what I can see, the items exhibit a textured, aged patina and casting irregularities consistent with period production. However, I cannot verify the specific metal composition or the age of the casting from a photo alone; these could be contemporary reproductions made to mimic an aged aesthetic. The estimate assumes the pair is of significant scale and weight, as larger sculptural 'jacks' are currently in demand for interior design. I can't determine the presence of maker's marks, such as those that might be found on pieces attributed to designers like Curtis Jere, which would significantly increase the value. If these are modern mass-market replicas or 'in the style of' pieces without verifiable vintage provenance, the value would likely decrease to the $40–$80 range. To arrive at a more precise valuation, an in-person inspection would be required to assess the weight, cold-feel of the metal, and any hidden marks. Confirmation of authenticity would necessitate provenance documentation or a physical comparison of the casting patterns against known period examples. The market for Brutalist tabletop sculpture remains stable, particularly for items that function as both art and utility, such as bookends or paperweights. This estimate reflects the current market interest in the Mid-century aesthetic for home decor.
