Caesars Palace is again offering "money books" for sale.

Caesars Palace is famous for offering for sale money that is glued on the edge to form "books." You can buy these "books" of new currency at face value -- there is no premium -- and the money can be peeled out. These have always been popular gift items.

For a while, Caesars discontinued making and selling its "money books" and it was because the casino cashiers were short-handed and they didn't have the time to glue the currency to create the "books."

Well, they're back in business. However, currently there are no $2 money books available.
