The 2p and 1p coins struck before 1992 have a copper content which, due to the high price of copper, makes them worth just slightly more. The famous undated 2008 20p coin is worth from £60 - £100 (100,000 were struck in error with no date on the Queen's head side). 1983 2p coins (still legal tender) which were issued in sets with 'NEW PENCE' instead of 'TWO PENCE' can sell for £400 - £600. They are very rare. Many early decimal coins in UNC condition can sell for more than their face value. Consult SPINK's 'Coins of England and the United Kingdom' for more information.
