Watch List notes:

Commemorative Medals, Admiral Augustus Keppel (1725-1786), the Battle of Ushant, copper medals (2), 1778, signed IH, uniformed bust three-quarters r., rev. JUDICIOUS / BRAVE / AND / GALLANT within wreath, one without reverse, 40mm and 39mm (BHM 214; Eimer 774; MH 437), very fine and fine (2)
It would appear that the first was indeed struck without a reverse, rather than having it removed.
