More importantly, the existing £1 coin appears to cease being legal tender in mid October!
From bbc news website (link at end of post)
"The new 12-sided £1 coin will enter circulation on 28 March, the government has said.
The round £1 will be legal tender alongside the new, more-secure coin until 15 October.
The public are being urged to use their current £1 coins or bank them before they lose their legal tender status."
Please, if you come over to the uk this year before October, spend the £1 coins (unless they are the new 12 sided ones) or quickly change them back into your home currency, otherwise later in the year you may not be able to use them

I am surprised how soon the existing coin ceases to be legal tender!
