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.
