Finally got around to going through a big envelope of GB on paper and trimming off all the excess paper to reduce weight. While doing this I see there are quite a few high value multiples. Is there any market for this stuff?
Here are some examples of what is in the mix.

Including a gutter pair and the top left looks like a booklet or sheetlet trio?


Some high value Machins

The 1992 - 1995 Castles with the syncopated perfs. The 1993 Britannia 10£ cats at $12.50 in my 2009 Scott for used alone, let alone on piece.


And some postage due multiples.

This is only a portion of what I found. Would this be considered better kiloware? Or pretty common for the time frame?
