I can't speak for the other papers, but the Daily Mirror ones were issued in about 1997 as a set of, I think, six. I have five of them and the ones in your photos are exactly the same. The reproductions are eight pages long. As I recall, there is some subtle difference between the original front pages and the reproductions. I'll have a poke about.
I'm afraid I don't know whether they're worth selling. The ones I had came with a double vhs set, one video was a documentary and one I think a dramatization but I can't remember the titles. This was 15+ years ago.
