I guess I should've been more specific in my original post. When I'm talking about determining whether or not a card is a Green Tint, I am specifically talking about looking at just a single card. If you have both the GT and the regular card side by side, it is incredibly easy to see the differences in the two. But if you're looking at a single card and are trying to determine if it's a GT, it can be very tough at times. Some tips are definitely useful.
With Mack Jones, for instance, the giveaway is the appearance of that blue line in the background at left. If it's there, you have a GT.
