This reverse type with the plain angles, is attributed by both Burns and Stewart to Prince Henry, Earl of Northumberland and Huntingdon. This coin appears to pair a reverse die type used for the ENCI COM coins of Prince Henry with an obverse die naming David I. Both are known to have struck coins at Carlisle. Carlisle was under Scottish rule from 1139, when Stephen ceded Northumberland and Cumberland to David I, until 1157 when Malcolm IV surrendered them back to Henry II.
