Vintage stick pin, a type of jewelry typically used to secure neckties, cravats, or lapels.

Because the piece lacks a precious metal stamp (such as "925" for sterling silver) or a designer signature (such as Sarah Coventry or Weiss), its value is driven purely by its aesthetic appeal to collectors of mid-century fashion rather than the raw material or brand heritage. 

Similar unbranded base-metal stick pins from the 1960s and 1970s featuring faux stones, rhinestones, or hematite cabochons consistently sell in this modest price bracket on online marketplaces like eBay and Etsy.

Unmarked vintage costume jewelry pieces in polished silver-tone settings generally value between $5 and $20.
