I have recently stumbled across some rather old items in my attac. How much are they worth today?

I would guess the Shakespeare and the Decca Gramophone have little or no value. Many, many complete Shakespeares have been published over the centuries and just because on is old won't make it valuable. You don't say what sort of gramophone it is - wind up for 78s only? Or electric and for long players? If the former there might be a little value in it from somebody who wants it as a decorative item.
