2013 coins circulating?

When are the 2013 coins arriving in circulation? I know some £2 tube commemarative coins have been circulating 'down south'. But where are the rest and why are there none up here? This time last year we had seen a few of the new steel clad 5 and 10p's already - this year: none!

It's quite a serious issue because for the low budget amateur, the quick plucking of new coins from circulation is one of the greatest thrills! Hopefully there will be some soon!
