There appears to be two packages for this one.
The one that I have was only sold on the Royal Mint web site for short period of time.
It was first released in a different package at the Royal Mint Visitors Centre in Wales and appears to be still on sale there.
So the Royal Mint calls the one that I have is the third 20 for 20 release for 2016 just because of the package the coin comes in.
