Old glass fishing net float hanging in a local restaurant, there is a price tag on it that says 300 dollars. Some floats can be over a hundred years old, but some can also be newly made. They come in many colors from blue, green, red and even a rare yellow. Tho most are blues and greens I see around different places for sale. This one is about twelve inches across.
I see a lot of small ones for sale that are about seven to ten dollars for ones that are four inches across.
Some have old original net rope on them with barnacles, this one looks like it has new net rope on it.
I've never found one on the beaches here but I have heard people do find them up along the far end of Kachemak bay down by Homer Alaska.
Check out this guys youtube videos, he fly's to remote beaches in his bush plane and finds loads of them! Its amazing how many are out there waiting to be found!
