One of the 1997 £1 coins is fake. It should be three lions for 1997. If you look you'll notice that there should be no coins dated 1972 in circulation. What you can expect to find; 1p = 1971, 1973-2004 (all dates) 2p = 1971, 75, 76, 77, 78, 79, 80, 81, 1985-1998 (two versions of 1998 [or was it 99?], one's magnetic, one is not), 1999-2004 (all dates) 5p = 1990-1992, 1994-2004 10p = 1992, 1994-2004 20p = 1982-1985, 1987-2003 (i haven't seen an 04s). 50p = 1997-2004 £1 = 1983-1997, 2000-2003 (i haven't seen any 04s) £2 = 1997-2003 (i haven't seen any 04s) Other denominations exist, pre-97 £2 coins, £5 coins and 25p (Crowns, 1972, 77, 80 and 81) but they don't tend to circulate.
