Rob I would like to see the addendum to Pecks work (from the 1967 Journal) ! Varieties were very popular in the monthly (and some fortnightly) coin magazines from the late 60's.....there was a lot of study. This information is out there and just needs processing. There is always room for specialist publications ie..George 11 currency farthing varieties... but for Spink or any other publisher to try and encompass everything into a yearly catalogue would be a folly. I think Chris is going the right way about it in CCGB with notification of a variety so the collector can carry out his own research. Of course I would love to see CCGB go back to the 1st milled coinage...but this would be a more specialist market for which I would imagine "slightly" more than £5 a chuck will be required. Going back to Colin Cookes website ,I agree its not complete...but his farthing catalogues contain far more information.eg catalogue 37 (about 6 years old) has 8 listed varities for the 1721 1/4d. They say there is a book in everyone....no excuse's we all have access to the computer,net and forums such as this.
