From what I've read so far, the Mint has been promoting the commemorative $2 baby wolves specimen set and holdiay sets as the last ones to contain the 1 cent coins.
Dealer ads suggest this lowly denomination will no longer be included in collector sets. Already some of the lower priced uncirculated sets have seen the omission of the 50 cent piece, yet they remain in the more expensive ones.
Guess we will have to wait and see if the Mint follows through.
