I have not attempted to rank the Wreath proofs by date in terms of scarcity-
I did offer a ranking for the George II Crowns by year on another forum about 4-5 years ago- excluding the 1732 and 1746 proofs.
Sent it you Jon via mail.
They were sent out this morning PDF and the hard copies in the next couple of days.
Large collection of Halfcrowns/Crowns although i dont buy them most dates are included.
Pete.
