Coach Daisy Keychain Description: It is a vintage or rare Coach keychain featuring a daisy flower design. The daisy is typically made of enamel in colors such as hot pink, as seen in the image, or other colors like light blue. It functions as a key fob or a purse charm. No, not all Coach Daisy charms are stamped on the back. While some genuine Coach Daisy charms do have the "Coach" logo or other markings on the back of each daisy or on a small metal hangtag, it's not a universal rule.
