I will try and get it weighed. I don't think it is fake though. How much should it weigh? I know there are fake £2 coins I've had a few of them at work. This one sounds the same as other 50p's when you drop them. Have you seen my 2014 10p? The royal mint want me to send it to verify it's authenticity, but I've had coins go missing in the post before so don't want to send it.
