In the second half of the 1990s and right up until they went bankrupt, Fleer issued so many different card sets it was near impossible to keep up. And sets would come and go. If you found a set one year that you liked, good luck finding it the next year. Fleer/Skybox will issue 12 different card sets in 2000. Of course the other companies were issuing lots of cards as well, but there was less stability from year to year with Fleer.
2000 was the inaugural year for Fleer Focus. It's first year of two. I bought a hobby box on May 2000 for about $0.24/card.

Fleer Club 3000
There are 14 base cards and 71 memorabilia cards in this set. The cards celebrate players who have either 3000 hits or pitchers who have 3000 strikeouts in their career. They were inserted in five of the Fleer branded card packs, Fleer Tradition, Fleer Focus, Fleer Mystique, Fleer Showcase and Ultra. The cards are not numbered.
