I haven't started a sideline £2 collection yet. However, what with this recession and all that, I'm making the most of it by getting my decimal collection knocked into shape (of course, looking out for great pre-decimal coins all the while). Doing pretty good for pre 1992 2p, 5p, 10p and 50p - have almost all of them in Unc ... and it's quite interesting how the Unc/BU coin values have been creeping up. A couple of years ago on eBay I picked up the 10 £1 coins 1983-92 on eBay for about £12 and postage (sent to the US). Also a complete set (Unc or FDC, where needed) of 5p coins 68-98. It makes for a good challenge anyway, I think!
