i think that you have missed a page...you say that proofs start on page 65 but it is page 64 on the pdf... ...also, spink is selling 1860 and 1861 'non-intended' proof farthing for £350 (each) ...also, colin cooke lists 3 specimins of 1860 copper proof, so its not unique ...also, on page 40 you have the 23mm (at top of page) going into the box with 1st rev and 2nd rev type shillings
