There have been some discussions about the new Cherrypicker's Guide due out later this year.
I asked the publisher (Dennis Tucker of Whitman Publishing) and this is his reply:
Hi Frank,
Yes, the 5th edition, Volume I, will be out by the end of the year. It covers
Half Cents through nickel five-cent pieces, so there won't be any updates in the
Barber halves... that will come with the 5th edition, volume II, probably next year.

P.S. For those who don't know me, I am a Barber nut, hence the notation.
