I have all of the NBA teams in basketball cards from NBA Hoops 1990, Is this collection worth anything?

Cards from that time the late 80's to early 90's have no value. Sure a Michael Jordan base card might be worth $1 or $2, but for the most part all the other cards are worthless from 89-94.

Card companies made hundred of thousands of copies and they are not in demand as they were back then.

Now cards are serial numbered and have autos, jersey, or even patches on them to make them more valuable and in demand.

The Jordans are maybe worth a dollar or two, the rest aren't worth the paper they're printed on.

I'd guess the entire collection is worth about $10.

they do have some value but not a very high one. They might be worth a dollar or two a piece but they aren't anything special. Maybe if you sold them to a card collector they would take them for a reasonable price if you don't want them.
