Aren't all the 2015 coins bearing the new effigy, I'm definitely missing out if both effigies are on the 2015 coins? I haven't actually checked the busts, but have been salting away any and all new 2015 coins in collectable condition, as I did for 2014 and 2013! A fractionally more sensible loose change "pot" akin to the one everybody else has stored in a bells whiskey bottles!
