The pound in your pocket...

A recent report has suggested that around 1 in 20 of all pound coins are forgeries. When you hear this, it's human nature to get the coins out of your pocket or purse and examine them. And yet, that's the last thing you should do. Once you know, or suspect, that a coin or note you have is counterfeit, it immediately becomes worthless - and worse, if you pass it on, that's a serious criminal offence. On the other hand, if you don't know... so this is one area where ignorance really is bliss!
