2000 Bowman Chrome was a full parallel set to 2000 Bowman, all 440 cards. I own exactly 4 cards from the set - the Astros. The cards have the same design as 2000 Bowman with the addition of the Topps Chrome technology.
The set had some different parallels and inserts from the base set.
As with all Chrome sets there are Refractor parallels but I don't have any. This is before the days when there were multiple kinds of Refractors (like X-Fractors) or colored bordered Refractors.
As with the base set there were the Future/Retro parallels. I only have a Future.
There were a couple of other insert sets which I don't have yet: the 10-card set called "Meteoric Rise" and the 15-card set called "Teen Idols". Both of these had Refractor versions.
There was also a 110-card Chrome parallel for Bowman Draft Picks, available only as a factory set. I only have one of them and I don't know how I got it. The only reason I even know it's from the Chrome Draft Pick set is by comparing checklists.
That almost does it for 2000 Bowman products. All that's left is Bowman's Best.
