Year sets, first day covers, unc coins in presentation cases and packs including £5 coins and Olympic 50p... to swap

Hi. I'm having a sort out of my duplicates and have a number of first day covers and year sets available to swap. Ideally I'd like to swap for other year sets, unc coins or commemorative coins but open to swap offers. Several of the coins are very low mintage and that's reflected in what I paid for them but will strive to do fair swaps.

I have several different UK Olympic 50p coins in sealed retail packs (more types than shown in the photo but not the full set of 29 - I also have vf circulated coins of most)

1994 and 1995 UK year sets including £2 coin
