Thanks for your comments about my Victorian Copper Penny pictures Jerry; also Mike and others.............. glad to be able to help.
Whilst authoring a book has a certain 'prestigious'' appeal, in this day and age I don't actually think it is the best way of sharing / improving knowledge about coin varieties, particularly as new discoveries are made and regularly need adding to the knowledge base.
I much prefer to have available to me websites such as Richard's englishpennies and rarestpennies sites, this Predecimal site, MG's website (which he has kindly kept going), or even past auction results (e.g. London Coins). A potential problem in coming to rely on these sites is, however, that they may of course disappear one day when site owners can no longer maintain.
I definitely think that reference material for the 1839-1860 Victorian Penny varieties would benefit from being pulled together from these various websites, and other sources (e.g. Bramah and Peck), and probably introduce a completely new indexing method at the same time. Prior to that I think there would need to be discussion, for example from members of this forum, about how to do that, what to include and not include, and by providing examples from their own collections.
I think I may try to do my next post on 1843 Pennies, giving a couple of examples to demonstrate how difficult such a task might be.
