Silver an PM nutts like us lot on this forum buy em lol Just received a few more today in the post too.. -E2A: Wouldn't part with my Lunar Dragon, tis my Birth sign sort of thing and pretty besides.
I know this might sound a bit silly, but I have an Australian 1966 round 50c which I received in my grandma's will about 10 years ago. It was out of a large bag that she'd stockpiled and left to me. I sold the rest of them when I was in need of some cash a few years ago - which i regret at little now - but held on to one as a keep sake. It sits on my computer desk and brings vivid, happy memories to mind, whenever I see it.
I think that this gold Britannia would be the last individual coin that i would sell though I would really mourn if my last Lunar series 1 were gone.
