Gold-tone botanical leaf-motif brooch

This item is a costume jewelry brooch designed in the shape of a botanical leaf, possibly representing a maple or grapevine leaf. The object measures approximately 1.5 to 2 inches in length when compared to the 2019 US penny provided for scale. It features a bright yellow gold-tone finish with a textured, slightly concave reverse side that exhibits molded vein details consistent with mid-20th-century nature-inspired costume jewelry. The construction includes a standard pin-back assembly with a straight pinstem and a rotating safety clasp. On the reverse, there is a small, rectangular raised cartouche located on the pinstem assembly; however, the mark is not clearly legible in the image, appearing blurred or worn. This makes a definitive maker identification impossible without further magnification or physical inspection. The surface shows minor signs of wear and age-related patina, particularly near the clasp and edges. The piece is stylistically consistent with mass-produced costume jewelry from the 1950s or 1960s, a period when botanical motifs were highly popular. A hedged name is used here because the maker's mark cannot be read from the photograph, and physical testing is required to determine the base metal or plating quality.

Based on the photograph provided, I have examined this gold-tone botanical leaf-motif brooch. This piece appears to be a mass-produced item of vintage costume jewelry, likely dating from the mid-20th century. While I can observe a rectangular cartouche on the reverse, the mark is blurred and illegible in the image. For the purposes of this estimate, I am treating the item as an unattributed piece of mid-market costume jewelry, as I cannot verify the maker without physical inspection and magnification. The construction, featuring a standard pin-back and rotating safety clasp, is consistent with styles from the 1950s or 1960s. The value estimate of $15.00 to $35.00 reflects the general market demand for nature-inspired vintage accessories in fair to good condition with minor surface wear. Because I cannot confirm the base metal or the thickness of the gold plating from a photo, this value assumes a standard non-precious base metal. If a physical examination were to identify the mark as belonging to a highly collectible maker of that era—such as Trifari or Boucher—the value could potentially increase to the $45.00 to $75.00 range. Conversely, if the piece is a modern reproduction in the style of mid-century motifs, the value would likely sit below $10.00. To reach a more certain conclusion, I would need to perform an in-person inspection to test the metal content, examine the hallmark under 10x magnification, and check the tension and security of the pinstem assembly. At present, this estimate is based on its aesthetic appeal and the typical market behavior for similar unauthenticated botanical pins.
