It would be good if we could all agree how to count date widths. This is something I raised with MG shortly after his book was published back in 2009 because to me he seemed to be consistently adding 1 to the date widths which I was counting. Apparently I was not the first person to have raised this with him. His response indicated that his method of counting teeth is to include both teeth which the first and last numerals are over as a full tooth each rather than half a tooth each. Referencing Page 76 of his book, for example, where 1880 date widths are described, if you look at the narrow date type BP 1880 Aa (M +k) he catalogues this date as having 12 teeth, which is 10 full teeth plus the 2 half teeth which the first and last numeral 1’s are over, both of which he counts as full teeth. So instead of being 10 + (2 x 0.5) = 11 he has decided to describe as 10 + (2 x 1.0) = 12. He has used this method consistently throughout his book, the only anomaly being the 1881 date where the first 1 is over a gap rather than a tooth, so if you look at the adjacent page 77 at type 1881Ca he describes as having 11.5 teeth whereas strictly speaking there are only 10.5 (i.e. he still adds 1). All date variety collectors will now find it difficult if we adopt different methods to describe our coins to one another, so I would suggest that as Gouby’s book is the main reference point for describing date widths that we all try to use his method? I also attach a picture of a coin I have kept because it seemed to me to be the missing 1880 Ac date width. On Page 76 MG lists Aa, Ab and Ad, but no Ac. His Ab and Ad have the centre of the numeral 0 (zero) directly over a gap, whereas my coin has it more towards the centre of a tooth. So if we use MG’s method of counting then this would be a date width of 13 teeth, 11 full teeth plus 2 bits (almost halves) = 13 (not 12). Hope I am helping rather than serving to confuse. P.S. If Terry’s got lots of 1877 narrow dates I wouldn’t mind one, doesn’t have to be UNC!
