I have 9 cars of star wars the empire strikes back collection and was wondering if you could help me price them

At most cards shows you see these for 50 cents, maybe a $1 if in mint condition.

Depends which cards they are and their conditions.  Boba Fett #11 tends to go for more than the others (ungraded I've seen it go over $20 and graded 8 or higher I've seen it sell over $300), as does Yoda #9.  Those are the highest valued that I'm aware of off the top of my head.  Series 3, the yellow and green border cards are also higher in value since they are the hardest to find (I'm willing to trade if anyone has any... see my want list if you do!).
And the stickers, since most kids stuck them to things, tend to also go for a little more.

For the majority, I think Bruno is fairly accurate at 50 cents to $1.

also if you have the error C3PO "x-rated" card  ( https://www.tcdb.com/ViewCard.cfm/sid/72964/cid/6495236/1977-Topps-Star-Wars-207-C-3PO-(Anthony-Daniels)?PageIndex=1 ) it can be a $100+ card ungraded 

As of 2022, that card came in #8 as far as the most valuable star wars cards.  A PSA 10 version sold for $4,999 in May of 2020.
Star Wars card #1 with Luke, graded a PSA 10 sold for $55,260 Nov 2021.  A PSA 9 version sold for $7,699.

But now we're talking the original Star Wars, not Empire.

I go to the wrong shows
