Thank you all for the comments, much appreciated.
I am a complete novice as regards Tolkien.
However these three books are the "Deluxe Edition" of the 1st printings produced in 1954 and 1955.
The deluxe editions were produced in 1963 and were distributed, due to slipcase problems, in 1964. (Mine was eaten!).
As is usual with Tolkien, very few ended up signed.
I hope this helps.
