Nerd indeed! You are paying for the beer Rob. I must admit talking about the die varieties of the 1887 sixpence has often put grandchildren to sleep. There are many unique pieces in the collection including varieties of the 14 pearl sovereign, some patterns by Lauer, and J R Thomas. Plenty of proof varieties that just are not listed anywhere and so many crowns with different rim sizes. OK I will accept slightly off the spectrum but that is what research is all about. This one is unlisted
