They first showed up back in 2007 but the only thing I have ever seen them used for are bulk submission promotional items being sold by the TV coin show people. Usually HSN. Usually they have some kind of specialty label Presidential dollar first day of issue, Bicentennial of Lincolns Birth cents first day of issue etc. This is the first one I've seen something that looks like a standard type label and the reverse label is also different that the other slabs of this style.
