Look at this adorable vintage valentine red metallic flower pin by Coro. It is a real beauty. I think it resembles a carnation although one could make a case for a porcupine! There is a black tip on most of the layered red petals. The apparent lack of color in the center petals is a fading of the color and not dirt. I know because I tried to clean it thinking it was dust.
This round valentine red vintage Coro metallic flower pin measures approximately two inches in diameter. It has a rolling C clasp which works well. It is in excellent vintage condition and is hallmarked Coro on the back.
