Jerry's Nugget playing cards

In 1970, the North Las Vegas casino printed a special deck of cards, and sold them in their gift shop for fifty cents. Almost forty years later, Jerry's Nugget playing cards fetch upwards of $1500 per brick (dozen) on ebay.

What makes these 54 pieces of cardboard so popular? ...the color? ...the design? ...the feel?


Or the fact that they just got Grippoed!?
