Remember when credit cards were paper? Or when Carl Malden was the spokesman for American Express? Then you might enjoy “Plastic Flashback: A visual history of the credit card” on Slate’s Big Money blog.
Do you have any old credit cards? It turns out they are highly collectible. A first-generation, paper American Express card can fetch upwards of $1,200. Not bad for a piece of paper. And maybe enough to help you put a dent in your current credit card debt!
