A couple months ago, I read about a special 50th anniversary Mini coin made available free by UK’s Royal Mint; it had to be shipped to an English address, but that’s no problem for me (thanks, Dad!) … my Dad sent on the coin and it arrived recently, a nice addition to my ever growing MINI collection:
While visiting the Royal Mint website, I found (surprise!) that they also offered a £5 coin, in a nice presentation, at not too expensive a mark-up, so I ordered one of them as well (this can be shipped straight to USA, happily, so I’ve had it a while):

So I went to the website and found a few selections, all pretty kool. Might need to buy a few.
