Merlen, a Flemish engraver who had worked at the Paris mint under the First Empire, was engaged at the Royal Mint on the recommendation of Pistrucci. He was much admired as an engraver of detailed armorial bearings, and Hawkins describes this reverse as 'eminent for the neatness, elegance, and minuteness of detail'. The signature is not noted in ESC, but see Davies p.36 note.
Merlen made a very similar reverse for the Shilling, and there is an unrecorded example of a signed proof, dated 1820, in this sale, lot 553.
