1994 Two Pounds Coin Trial Piece
The new type of £2 coin introduced in 1997 featured an innovative bi-metallic design.
It was the first base metal two pound coin to be intended for circulation in the United Kingdom. It was also the first time that a bi-metallic coin had been used for British coins.
The inner disc is made of cupro-nickel, while the outer ring is made of nickel-brass.
In 1998, the Royal Mint released a number of "trial packs" containing a 1994 dated trial "£2 Coin", but also containing three blanks showing stages in production.

Production Method

First Stage - Alloying
The first stage in the manufacture of a two-pound coin is the melting and alloying of its constituent metals in electric induction furnaces at temperatures of between 1300° and 1400° Celsius. The bi-colour nature of the new coin means that two different alloys must be processed separately.

Continuous Casting
In either case, once examination by x-ray fluorescence spectrometry has confirmed that the alloy is correct, the molten metal is continuously cast, from a holding furnace, through water-cooled graphite dies. The emerging strip, 210mm wide by 15mm thick, is cut into manageable 10m lengths and its upper and lower surfaces are scalped by up to 0.50mm to remove oxide discolouration.

Rolling
Two passes through a tandem rolling mill reduce its thickness to 3mm and in so doing, double its length. Because the nickel-brass will now have become work-hardened, the strip must be softened by an annealing process of seven hours duration in a furnace at 600° Celsius. The strip is reduced to the desired thickness for coining by being accurately rolled on a reverse finishing mill. At this point the now extended strip has been accurately reduced to coin thickness.

Punching Out the Blanks
Cupro-nickel and, at this stage, whole nickel-brass coin blanks are punched out of the strip at a rate if up to 5,000 per minute with a force of 100 tonnes. The metal residue from the blanking process, known as scissel, is returned to the furnace.
The blanks are softened in annealing furnaces operating at temperatures of up to 950° Celsius. After cooling they are fed into automatic blank finishing machines, where stains are removed by a solution of sulphuric acid. They are then burnished and finally rinsed in water and dried off.

Edge Rolling & Lettering
The outer blanks of nickel-brass are given raised edges by being rolled under great pressure between the fixed segment and rotating wheel of a rimming machine. It is also at this stage that the coin's edge lettering is applied. Central holes, which take the smaller cupro-nickel blanks, are punched out on a piercing press. The rimmed inner blanks meanwhile receive an edge groove as a key to bonding.

Striking the Coins
A coining press is served by two separate hopper and feed systems for the different blanks. The first system feeds the pierced outer blank into a dial plate segment, which then moves on to the second operation. there the inner blank is dropped into position, loosely located inside its outer. Held by the segment, the coin parts pass on to be brought to rest on top of the lower die, whose upward movement pushes the blanks into a restraining collar. Continued upwards movement of the lower die squeezes the blanks against the upper one with a 100 ton force, so that both impressions are received in a single operation. By the same action the metal, being forced outwards, takes up the pattern of the milled collar, and the union of the two coin parts is made.
The completed bi-colour two-pound coin is ejected from its collar by a downward movement of the upper die.

Obverse
The Third Portrait
The obverse (head side) bears the third major portrait of Queen Elizabeth II, designed by Ralph David Maklouf, FRSA.
It came into use in 1985 and continued until 1997 inclusive, a total of thirteen years.
The queen is shown wearing a pearl necklet. In the second year of issue 1998, the portrait changes to the fourth portrait, showing more mature features, and without the necklet. Please see "The Two Pounds Story" for details of the quite unfounded rumour.

Reverse
In the centre, a three-masted sailing ship, similar to that previously used on halfpennies of George VI and Elizabeth II, the outer ring bears the inscription:-
ROYAL MINT TRIAL
1994

Edge
DECUS ET TUTAMEN ANNO REGNI XLXVI
The edge is milled and also carries an incuse inscription.
The edge inscription translates as "An ornament and a safeguard" - "The 46th year of (her) reign (=1998).
