“There are seven others from the same obverse die as this one, with an inverted design. Four have a right-facing horse on the reverse and three a left-facing horse, as here; this one’s from a new reverse die and important as such. There’s a fourth left-facing specimen from a different pair of dies, 63.0009, which has a rosette as well as a pellet below the horse. The group as a whole stands at the transition between the pellet type and the rosette type at my Mint B, which may help to explain its unusual features. There’s another inverted obverse variant later in the series, which is commoner, but it’s in a different ‘crude’ style and not closely related to this one. This type of error seems to have been caused by an engraver copying a coin rather than a die, resulting in a ‘mirror image’ design.”

Thank you for your email. Most interesting. It’s not the case that the coin is so rare that it isn’t recorded in ABC as we obviously have lots of rare and unique types in there, it is simply that the North East Coast is a huge series with many variants and when we published in 2010 we had to make a decision as to which we included.
