Hey
You have some Power of the Force 2 green cards (1997-1998ish)
All three of the 25th anniversary 2 pack scene & the 300th figure Boba Fett which were maybe late 90's very early 00's (can't remember exactly when they came out)
I think the value of POF2 and a lot of that line is still low - so individual figures tend to be between £5-£10, some less some more, just depends who is after what, ebay recent sales is a good guide (Don't look at the BIN stuff, lots of ridiculously priced stuff that never shifts there)
i think the anniversary sets are a bit better, may £20ish each. I have seen the Boba go for £30+ if he is in good nick and depending on which version, there was one with a white side on the packaging and one without if memory serves, but i can't remember which was the rarer one
Personally i like these figures, but they are mostly low value and a lot out there.
