Yes, this is one of the most magnificent pieces in the world, & I feel honoured to own the full three-piece set in its original mint case.

Thanks, Chute. I do carry on a bit... but then They don't let me out much so I take what I can get!

Publius, thanks. My coin has its original little midnight blue, satin-lined sheath. I'd love to see a pic of your set if you don't mind.

Ultra, thank you! You remind me that I did google a translation a few years ago when I first found this little treasure. 'Til your comment, I'd forgotten all about it. My brain leaks, lately.

And Bart, you are a doll! Iceland makes so much more sense... I'm Scandanglo and the Greek thing triggered my brain's ABS system and that's never a good thing.

Thank you all so much for sharing your brainy bits... Cool group!
