These were pins 0480 - 0482. The combination of green shard and pink logo which should have been pin 0479 was never released.
There are 3 pins in the range - the standard shard pin and one pin each showing Wenlock and Mandeville. Mandeville's pin has the date 11/02/2012 as this is 200 days until the Paralympics.
This seems a good time for a round-up of all the sold-out pins. If you need any of these for your collection, act quickly!
