A metal detecting find of a Henry II short cross penny appears to be from previously unpublished dies of Turkil of York. The article describes and discusses the coin, and concludes it is a class 1a2 penny, or a 1a2/1a1 mule, both of which have not previously been published for Turkil. The condition of the coin does not allow a firm identification at this time, and we hope that further examples from these dies will emerge in due course and allow a firm identification.
