I thought that these cards were the CUTEST IDEA! Each one comes with a scratch off sticker that you apply over the top of part of the sentiment, and then you add a coin and the person you give the card to gets to scratch off the card to see the sentiment . . . which is usually a punch line to a riddle or joke.
I even got to make one in a Make and Take

I love it! what a great idea
