My collection at work is getting pretty interesting ill post a pic for you, I have about 25 £1 coins, various dates and faces, and metals too, and around 4 or 5 £2 coins, my favourite is a pound coin made from a silver coloured alloy, the colour is 100% wrong! lol   There is a coin made from bi-coloured metal with arabic script that gets used as a £2 coin quite often as well.
