If you've seen the "Card Game" on "The Price Is Right," you notice that there used to be 12 Jumbo Bicycle (Blue Back, Blank Face) playing cards. Each of them has different dollar amounts on them. That's why I recently purchased 13 Jumbo Bicycle (Blue Back, Blank Face) playing. I'm building my own Card Game. If you're a huge fan of "The Price Is Right," & if you really like the "Card Game," I definitely recommend this. It's absolutely worth it.
