Collection of Antique Victorian Aesthetic Movement Doorknobs and Backplates

This is a diverse collection of antique architectural hardware, primarily consisting of ornate brass and bronze doorknobs alongside matching circular escutcheon backplates. The set features prominent designs from the late Victorian 'Aesthetic Movement' era, characterized by intricate, cast geometric and floral patterns. Visible are several distinct motifs, including a high-relief 'sunburst' or radiant flower pattern and a more structured 'cross-and-shield' circular design. The materials appear to be cast solid brass and possibly bronze, showing a varying range of patinas from bright gold-toned brass to deep, oxidized chocolate brown. Many of the knobs are still attached to their square iron or steel connecting spindles. The craftsmanship of the casting is high, showing fine detail in the filigree and recessed areas. Regarding condition, the pieces show evidence of age and use, including surface scratches, tarnishing, and some verdigris buildup in the deeper grooves of the patterns. Some knobs exhibit minor denting on the edges. There are approximately 20-25 doorknob halves and about a dozen matching backplates. These pieces likely date from between 1880 and 1905 and were common in upper-middle-class residential architecture of the period. No specific manufacturer marks are visible from the top view, though such pieces were frequently produced by notable firms like Yale & Towne, Reading Hardware, or Sargent.
