There are 3 different varieties of cards from both of the Connecticut casinos.
The differences are subtle as described below:

FOXWOODS:
Each card has the same front with green marble design.
Back A: Original design. First paragraph ends with word "floor".
Back B: First paragraph ends with word "floor".

"Gaming Problem...." added at bottom of card.
Back C: First paragraph ends with word "department".

"Gaming Problem...." at bottom of card.

MOHEGAN SUN:
Yellowish sunset background is first design. There are 2 variations:
Back A: Original design. No website at lower right.
Back B: Website at lower right.
Purple sky background is new design - October 2001

I have traders for all 6 varieties. However, I only have a few the original
Foxwoods (Back "A") cards and they are in poor condition.
