The bi-metallic £2 coin is the largest circulating coin denomination of the Pound Sterling. It was introduced in 1998 (earlier two pound coins were made of Nickel brass, were intended as commemorative, and did not circulate much). Being bi-metallic means that the coin comprises two separate components of differing alloys - a Nickel-Brass outer ring with inner circle of CuproNickel.
The Royal Mint maintains a "definitive" style of the £2 issued annually, as well as a large variety of one-year circulating commemorative types and some Non-Circulating Legal Tender (NCLT) £2 coins for collectors. Between 1997 and 2015, the definitive type was the Technology type £2, which was then changed to the Britannia type £2.
The one-year type coins celebrate important anniversaries or people, as well as iconic aspects of British culture and history.
This circulating commemorative £2 coin marks the 500th Anniversary of Trinity House.
Trinity House was formed by Royal Charter under King Henry VIII in 1514. The organisation was tasked with improving the safety of Britain’s waterways and for 500 years Trinity House has tirelessly served the mariner. To honour the 500th Anniversary of this respected organisation, this £2 coin entered circulation.
The reverse features a design by Joe Whitlock Blundell, Production Director of The Folio Society, created with the help of David Eccles, a retired illustrator and printer. It captures the spirit of Trinity House with an enduring symbol of the seas - the lighthouse.
£2 coins issued in 2014 have now been in circulation for ten years. |
