Lost & found miscellaneous jewellery in South Florida

Found pins on the South Beach boardwalk.

I was strolling along the South Beach boardwalk near Ocean Drive around 11:20 a.m. today when I spotted a small cluster of pins lying in the sand. There are four pins in total: a shiny dolphin, a bright enamel 'Miami' pin, a tiny palm-tree pin, and a silver pin with a sun motif. They're not mine, and they looked well-loved, like someone uses them for jackets or bags. I took care of them and posted here, hoping the owner sees this and can reclaim them through the site.
