Nice find.
The big question among serious collectors is:
What version of the Cardinal 4 are we talking about?If it is the super rare Version 1, you hit the jackpot.
If not, then it all depends on the state of the reels.
Here's a set of guidelines and pictures for you to identify the version:
http://www.realsreels.com/IntroductionZebcocardinal4.htmZebco is Abu's USA offspring and the Cardinal 4 is one of its most popular spinning reels ever.
They are great Swedish made reels - I'd keep one around if I were you.
If you prefer to unload them, assuming they are in fairly decent condition, showing use, but not abuse, you should be able to get 75-100 bucks for each. Even if they are total beaters, you are likely to get 50 bucks for each.
I will only collect spinning reels if they bear the ABU Ambassadeur name, such as this one:

fleaBay.
Hope this helps,
