Both of these cards are from "Trump Plaza" in "Atlantic City". The background lettering on the bottom card is very light compared to the top card. Also the color on the inside of the crown above "Trump Plaza" in the bottom card is black while the color on the top card is gray. And on the back of the bottom card in the upper left corner it's marked "SC1" and there's no mark at all on the top card. The bottom card is in excellent shape so I don't think it has anything to do with wear. Is this a variation? Any help would be appreciated.

Thanks,
Victor
