I only got first set in a sealed box (before knowing there are two), and there are 160 cards in total there. Last two cards are checklists. 80 cards are from ST:TOS (odd numbered cards), 80 from ST:TNG (even numbered cards).

I didn't get any inserted hologram cards in the sealed box, which is a bit strange... unless they are all part of second set only. Or are simply more rare.

Two series... were they each 155 cards?

I have this set and in great condition... Is it worth anything?
