1999 SkyBox Dominion Football Forum

OK, several of the insert sets for the 99 Skybox Dominion Set come in 3 different variations: a base card, a "Plus" version, and a "WarpTek" variation.  I have several of these cards, but, quite frankly, am not sure which belongs to which sub-set.  I assumed that I don't have the WarpTek variations since the DB says they are serial numbered, but when I looked at COMC and other sites for images, I don't see any serial numbers on the cards listed as "WarpTek".  Does anyone know how to tell the variations apart?

The base are plain foil, you can probably see your reflection in them.

The Plus have less shiny foil, not sure I'd describe it as a hint of refractiveness, with a vertical textured design.

The Warp Tek have a honeycomb like-almost lenticular design. Only the Atlantatitude version is serial numbered.
