Does any one know what the Approx odds of getting a full set of chrome chase cards from a box of A new Hope or Rotj Widevision boxes?

No chance at all.Ten chromes in the set.One in eleven packs were the odds.Box has twenty--four packs,so if everything goes well will get two in a box.Brett

It is 1 in 12 packs for ROTJ Wide and 1 in 11 for ANH Wide

You would need to open a minimum of five boxes for each set but that is to presume you got all 10 different cards without duplicates at the odds stated which is unlikely. I know of some boxes that had 1 chrome card and some that had 3.

Just to finish it off ESB odds are 1 in 12.
