There are six of these in box as per photos, at the rounded end it appears to have

a place to place a cord of some sort. I would like to know what these are and their use, and what they maybe worth.

When I was about  4 years old my grandfather used to take me the dump and on one side of the dump was an old house that the sea was about to reclaim, managed to get in whilst it was just hanging in there,  I saw the cup way up on a shelf and wanted it so granddad  got it down for me and I have always had it, not long after that the house went into the sea.
