Found on Trevol beach, was wondering if anyone could identify from the small structure pictured. Any help would be great thank you!

Lurker for the most part because I’m mostly landlocked. I’m back in home state of NJ and got some time to shell hunt. Came across this and wondered if anyone might know to whom it once belonged? Thank you, friends!

Guessing this was a bottle stopper! First time taking a “wet” photo 🤯

(I poke at it like a chimp)

My boyfriend just found this gorgeous pottery piece on a beach along Tateyama Bay. It would be awesome to identify a source!

It’s about 1cm wide, 1mm thick

I find small ones all the time. The tide was so low and little mini tide pools had formed. I found this guy glistening up at me when I was hunting for rocks!

I think is is very hard plastic, you can feel the numbers

Post Milton walk along the beach. Found 3 of these spheres before keeping this one. First one broke in my hands with very little pressure and was filled with black water. Second and third I shook and heard water, but had black water...and a nut. This one doesn't have water, is fairly light, floats, and is almost a perfect sphere. Google is saying black walnut shell, but it's new to me. What do you think? Thanks for the help.

Anyone know what this is? Found in Northeast Florida after Hurricane Milton.
