gerry,
Go to the 'London' thread and practice posting the pics. Much easier for us all if we see the pics.
As for the stamps, the top left and bottom stamps are High Value definitives, quite common.
The others are QEII and KGVI Coronation Commemorative stamps, sometimes called Special stamps by Royal Mail. These are also common.
I won't post the pics on this thread, I'll let you have a go !

Good luck [again]
