Insular Cf is the earliest identifiable British gold coinage. It was derived from, and contemporary with, the later GB-Ca classes. It is split into two classes, with the first starting as a close copy of GB-Ca1, and the second being a much cruder copy. It is likely that the dies for the first class were cut by an experienced continental engraver who had worked on GB-Ca1, and the dies for the cruder second class were cut by a newly trained British engraver.
This coin is one of the class 1 coins.
