The design itself was first tried out in 1994 when the Royal Mint produced a short run of demonstration pieces to the new bi-metal standard. These pieces were not for circulation and were simply intended to test the manufacturing process. The coin was technically similar to the version which eventually entered circulation with the Maklouf effigy of Queen Elizabeth II on the obverse and the image of a sailing ship similar to that previously used on the reverse of the pre-decimal halfpenny piece. The inscription on the reverse read ROYAL MINT TRIAL 1994 with an edge inscription based on the one pound coin which read DECUS ET TUTAMEN ANNO REGNI XLVI, meaning "An ornament and a safeguard – the 46th year of reign". The 1994 pieces were never legal tender but were eventually released for sale as part of a presentation set in 1998. At the same time in 1994 the Royal Mint produced a mono-metallic trial two-pound coin, with the same ship reverse and inscription, but otherwise similar to the earlier commemorative coins. These were never issued in presentation sets, and so are much scarcer than the bi-metallic version.
