Shown below are some slot card variations. The Caesars AC card now has the Innovative mfg. mark, The Tropicana AC now has the Innovative mfg. mark, Bally's AC now says Bally's Atlantic City on the back instead of Bally's Park Place. Mohegan Sun has 3 slightly different backs. One has a small T in a circle on the lower left of the back of the card, the other two (without the T) have two differnt widths for the magnetic stripes, 1/2" and 7/16".
