The older one is rose gold color and has more patina (bottom in photo.) It probably dates from 1930-1950.
The newer pin is yellow gold (top in photo). It probably dates from 1940-1960.
Please call us to specify which pin you select.
Both pins are 2 1/2” long and close with a simple, pressure clasp. The horseshoe is intentionally hanging with the bars pointing downwards, in keeping with pre 1950 superstitions that the wearer should be bathed in Luck at all times.
