[caramelcard]

There's not an abundance of tobacco cards that are "faded by the sun." Makes no sense. And red cards don't fade to orange.

Cards that have had the color changed by a chemical are usually pretty obvious. Just use common sense if you're buying them. If they look fishy, severely stained, etc, then I'd stay away.

Certain cards (like Abstein for example) just have a wide amount of red/orange tones and are completely legit.
