Coro Leaf Brooch Value Guide

The Coro Leaf Brooch is a quintessential example of mid-century American costume jewelry, produced by the prolific partnership of Carl Rosenberger and Emanuel Cohn. This silver-tone piece represents the nature-inspired design trends that dominated the 1940s through the 1960s, making it a staple for vintage fashion collectors.

What affects the value of Coro Leaf Brooch?

• Condition of the silver-tone finish, as pitting or heavy oxidation can decrease the $25 market value.
• Clarity and depth of the textured metalwork details on the leaf's veins and edges.
• Functionality and original state of the pin back and rolling lock mechanism.
• Presence of specific era-appropriate hallmarks that confirm its origin between 1940 and 1960.

How to Identify Coro Leaf Brooch?

• Look for the 'Coro' script or block signature stamped on the reverse side of the silver-tone base metal.
• Examine the textured detailing on the leaf surface, a hallmark of Coro's mid-century botanical designs.
• Verify the pin mechanism, which typically features a classic safety catch consistent with 1940-1960 manufacturing.
• Check for the specific silver-tone finish which should show consistent wear rather than modern plating.
