In 1926 a competition was held in Britain amongst engravers and designers to come up with designs for the new upcoming coinages of 1927, Threepence through Crown. To the best of my knowledge, only three designer renditions made it to the actual production of patterns in metal. These were those of Kruger-Gray, McMillan (sp?), and (Derwent) Wood. All six of KG’s ended up being accepted; those of McMillan (I may have this name a bit sideways) were quite plain using monograms reminiscent of Alfred the Great, and finally those of Wood which had to my understanding been engraved by Humphrey Paget. This Threepence is the design rendered by Wood. Since the only design being contested was the reverse, the obverse side bears only the designation “MODEL”. The florin and crown by Wood IMHO were far superior to Kruger-Gray’s accepted versions - these depicted the Tudor rose and on the crown a reclining Britannia, beautifully done with “PEACE” on the inscription. this simple design of the Scottish thistle on the 3d is quite pleasant:
