The Mutombo and D Smith might be worth a dollar or two each mate, lots of the 'rare' stuff back in the early 90s is pretty easy to chase down these days.
The other pics are just base cards and are basically worth nothing. Might have bulk worth to a team collector or if you have a MJ might be worth a buck as well.
Nice cards though, remember busting a few front row packs back in the day!
